Regulatory History:
In connection with the recognition of IIROC and its adoption of UMIR, the applicable securities commissions approved amendments to Rule 7.2 that came into force on June 1, 2008 to make editorial changes. See Footnote 1 of Status of Amendments.
Effective December 14, 2022, the applicable securities commissions approved amendments to UMIR 7.2 to expand proficiency obligations to the trading of derivatives on a marketplace. See IIROC Notice 22-0140 – “Amendments Respecting the Trading of Derivatives on a Marketplace” (September 15, 2022).
For the purposes of Rule 7.1, a Participant shall supervise its employees, directors and officers and, if applicable, partners to ensure that trading in securities or derivatives on a marketplace (an Exchange, QTRS or ATS) is carried out in compliance with the applicable Requirements (which includes provisions of securities legislation, UMIR, the Trading Rules and the Marketplace Rules of any applicable Exchange or QTRS). An effective supervision system requires a strong overall commitment on the part of the Participant, through its board of directors, to develop and implement a clearly defined set of policies and procedures that are reasonably designed to prevent and detect violations of Requirements. The board of directors of a Participant is responsible for the overall stewardship of the firm with a specific responsibility to supervise the management of the firm. On an ongoing basis, the board of directors must ensure that the principal risks for non‑compliance with Requirements have been identified and that appropriate supervision and compliance procedures to manage those risks have been implemented.
Management of the Participant is responsible for ensuring that the supervision system adopted by the Participant is effectively carried out. The head of trading and any other person to whom supervisory responsibility has been delegated must fully and properly supervise all employees under their supervision to ensure their compliance with Requirements. If a supervisor has not followed the supervision procedures adopted by the Participant, the supervisor will have failed to comply with their supervisory obligations under Rule 7.1(4).
When the Market Regulator reviews the supervision system of a Participant (for example, when a violation occurs of Requirements), the Market Regulator will consider whether the supervisory system is reasonably well designed to prevent and detect violations of Requirements and whether the system was followed.
The compliance department is responsible for monitoring and reporting adherence to rules, regulations, requirements, policies and procedures. In doing so, the compliance department must have a compliance monitoring system in place that is reasonably designed to prevent and detect violations. The compliance department must report the results from its monitoring to the Participant’s management and, where appropriate, the board of directors, or its equivalent. Management and the board of directors must ensure that the compliance department is adequately funded, staffed and empowered to fulfill these responsibilities.
The obligation to supervise applies whether the order is entered on a marketplace:
In performing the trading supervision obligations, the Participant will act as a “gatekeeper” to help prevent and detect violations of applicable Requirements.
When an order is entered on a marketplace by direct electronic access, under a routing arrangement or through an order execution service, the Participant retains responsibility for that order and the supervision policies and procedures should adequately address the additional risk exposure which the Participant may have for orders that are not directly handled by staff of the Participant. For example, it may be appropriate for the Participant to sample for compliance testing a higher percentage of orders that have been entered by a client under direct electronic access, an investment dealer or foreign dealer equivalent under a routing arrangement or a client through an order execution service than the percentage of orders sampled in other circumstances.
In addition, the “post order entry” compliance testing should recognize that the limited involvement of staff of the Participant in the entry of orders by a client under direct electronic access, an investment dealer or foreign dealer equivalent under a routing arrangement or a client through an order execution service may restrict the ability of the Participant to detect orders that are not in compliance with specific rules. For example, “post order entry” compliance testing may be focused on whether an order entered by a client under direct electronic access, an investment dealer or foreign dealer equivalent under a routing arrangement or a client through an order execution service:
For the purposes of Rule 7.1, a supervision system consists of both policies and procedures aimed at preventing violations from occurring and compliance procedures aimed at detecting whether violations have occurred.
The Market Regulator recognizes that there is no one supervision system that will be appropriate for all Participants. Given the differences among firms in terms of their size, the nature of their business, whether they are engaged in business in more than one location or jurisdiction, the experience and training of their employees and the fact that effective compliance can be achieved in a variety of ways, this Policy does not mandate any particular type or method of supervision of trading activity. Furthermore, compliance with this Policy does not relieve Participants from complying with specific Requirements that may apply in certain circumstances. In particular, in accordance with subsection (2) of Rule 10.1, orders entered (including orders entered by a client under direct electronic access, an investment dealer or foreign dealer equivalent under a routing arrangement or by a client through an order execution service) must comply with the Marketplace Rules on which the order is entered and the Marketplace Rules on which the order is executed.
Participants must develop, implement and maintain supervision and compliance procedures that exceed the elements identified in this Policy where the circumstances warrant. For example, previous disciplinary proceedings, warning and caution letters from the Market Regulator or the identification of problems with the supervision system or procedures by the Participant or the Market Regulator may warrant the implementation of more frequent supervision or compliance testing and more detailed supervision or compliance procedures.
Regardless of the circumstances of the Participant, however, every Participant must:
Each Participant must develop, implement and maintain supervision and compliance procedures for trading in securities or derivatives on a marketplace that are appropriate for its size, the nature of its business and whether it carries on business in more than one location or jurisdiction. Such procedures should be developed having regard to the training and experience of its employees and whether the firm or its employees have been previously disciplined or warned by the Market Regulator concerning the violations of the Requirements. Participants must identify any high-risk areas and ensure that their policies and procedures are adequately designed to address these heightened risks.
In developing supervision systems, Participants must identify any exception reports, trading data and any other relevant documents to be reviewed. In appropriate cases, relevant information that cannot be obtained or generated by the Participant should be sought from sources outside the firm including from the Market Regulator.
Each Participant must develop written policies and procedures in relation to all Requirements that apply to their business activities. A Participant’s supervision system must at a minimum include the regular review of compliance with respect to the following provisions for trading on a marketplace where applicable to their lines of business:
Each Participant must develop, implement and maintain a risk-based supervision system that identifies and prioritizes those areas that pose the greatest risk of violations of Requirements. This enables the Participant to focus its review on the areas that pose a higher risk of non-compliance with Requirements. The frequency of review and sample size used in reviews must be commensurate with, among other things:
Each Participant must develop, implement and maintain a supervision system to ensure its trading does not violate Rule 5.3 -
The purpose of the Participant’s compliance review is to ensure that inventory or non-client orders are not knowingly traded ahead of client orders. This would occur if a client order is withheld from entry into the market and a person with knowledge of that client order enters another order that will trade ahead of it. Doing so could take a trading opportunity away from the client. Withholding an order for normal review and order handling is allowed under Rule5.3 and Part C of Corporation Rule 3100 – Best Execution of Client Orders, as this is done to ensure that the client gets a good execution. To ensure that a supervision system is effective it must address potential problem situations where trading opportunities may be taken away from clients.
Each Participant must develop, implement and maintain a supervision system to ensure that orders entered on a marketplace by or through a Participant are not part of a manipulative or deceptive method, act or practice nor an attempt to create an artificial price or a false or misleading appearance of trading activity or interest in the purchase or sale of a security or a derivative.
In particular, the policies and procedures must address:
A Participant will be able to rely on information contained on a “New Client Application Form” or similar know-your-client record maintained in accordance with requirements of securities legislation or a self-regulatory entity provided such information has been reviewed periodically in accordance with such requirements and any additional practices of the Participant.
While a Participant cannot be expected to know the details of trading activity conducted by a client through another dealer, nonetheless, a Participant that provides advice to a client on the suitability of investments should have an understanding of the financial position and assets of the client and this understanding would include general knowledge of the holdings by the client at other dealers or directly in the name of the client. The supervision system of the Participant should allow the Participant to take into consideration, information which the Participant has collected respecting accounts at other dealers as part of the completion and periodic updating of the “New Client Application Form”.
Each Participant must review a sample of its trading for manipulative and deceptive activities at least on a quarterly basis.
Each Participant must develop, implement and maintain a supervision system to ensure that an order:
Each Access Person must adopt written policies and procedures reasonably designed to detect and prevent an order marked as a “directed action order” in accordance with Rule 6.2 from resulting in a trade‑through other than a trade‑through permitted under Part 6 of the Trading Rules.
The policies and procedures must set out the steps or process to be followed by the Participant or Access Person to ensure that the execution of an order does not result in a trade-through. The policies and procedures must specifically address the circumstances when the bypass order marker will be used in conjunction with a “directed action order”. These policies and procedures must address the steps which the Participant or Access Person will undertake on a regular basis, which shall not be less than monthly, to test that the policies and procedures are adequate.
Trading supervision related to electronic access to marketplaces must be performed by a Participant or Access Person in accordance with a documented system of risk management and supervisory controls, policies and procedures reasonably designed to ensure the management of the financial, regulatory and other risks associated with electronic access to marketplaces.
The risk management and supervisory controls, policies and procedures employed by a Participant or Access Persons must include:
A Participant or Access Person is responsible and accountable for all functions that they outsource to a service provider as set out in Part 11 of Companion Policy 31-103CP Registration Requirements and Exemptions.
Supervisory and compliance monitoring procedures must be designed to detect and prevent account activity that is or may be a violation of Requirements which includes applicable securities legislation, requirements of any self-regulatory organization applicable to the account activity and the rules and policies of any marketplace on which the account activity takes place. These procedures must include “post-order entry” compliance testing enumerated under Part 1 of Policy 7.1 to detect orders that are not in compliance with specific rules, and by addressing steps to monitor trading activity, as provided under Part 5 of Policy 7.1, of any person who has multiple accounts, with the Participant and other accounts in which the person has an interest or over which the person has direction or control.
Trading supervision by a Participant or Access Person must be in accordance with a documented system of risk management and supervisory controls, policies and procedures reasonably designed to ensure the management of the financial, regulatory and other risks associated with the use of an automated order system by the Participant, the Access Person or any client of the Participant.
Each Participant or Access Person must have a level of knowledge and understanding of any automated order system used by the Participant, the Access Person or any client of the Participant that is sufficient to allow the Participant or Access Person to identify and manage the risks associated with the use of the automated order system.
The Participant or Access Person must ensure that every automated order system used by the Participant, the Access Person or any client of the Participant is tested in accordance with prudent business practices initially before use and at least annually thereafter. A written record must be maintained with sufficient details to demonstrate the testing of the automated order system undertaken by the Participant, Access Person and any third party employed to provide the automated order system or risk management or supervisory controls, policies and procedures.
The scope of appropriate order and trade parameters, policies and procedures should be tailored to the strategy or strategies being pursued by an automatic order system with due consideration to the potential market impact of defining such parameters too broadly and in any event must be set so as not to exceed the limits publicly disclosed by the Market Regulator for the exercise of the power of a Market Integrity Official under Rule 10.9 of UMIR.
The Market Regulator expects the risk management and supervisory controls, policies and procedures to comply with the Electronic Trading Rules and be reasonably designed to prevent the entry of any order that would interfere with fair and orderly markets. This includes adoption of compliance procedures for trading by clients, if applicable, containing detailed guidance on how testing of client orders and trades is to be conducted to ensure that prior to engagement and at least annually thereafter, each automated order system is satisfactorily tested assuming various market conditions. In addition to regular testing of the automated order systems, preventing interference with fair and orderly markets requires development of pre-programmed internal parameters to prevent or “flag” with alerts on a real-time basis, the entry of orders and execution of trades by an automated order system that exceed certain volume, order, price or other limits.
Each Participant or Access Person must have the ability to immediately override or disable automatically any automated order system and thereby prevent orders generated by the automated order system from being entered on any marketplace.
Notwithstanding any outsourcing or authorization over of risk management and supervision controls, a Participant or Access Person is responsible for any order entered or any trade executed on a marketplace, including any order or trade resulting from the improper operation or malfunction of the automated order system. This responsibility includes instances in which the malfunction which gave rise to a “runaway” algorithm is attributed to an aspect of the algorithm or automated order system that was not “accessible” to the Participant or Access Person for testing.
Standards for Clients, Investment Dealers and Foreign Dealer Equivalents
In addition to other trading supervision requirements, a Participant that provides direct electronic access or implements a routing arrangement must establish, maintain and apply reasonable standards for granting direct electronic access or a routing arrangement and assess and document whether each client, investment dealer or foreign dealer equivalent meets the standards established by the Participant for direct electronic access or a routing arrangement. The Market Regulator expects that as part of its initial “screening” process, non‑institutional investors will be precluded from qualifying for direct electronic access except in exceptional circumstances generally limited to sophisticated former traders and floor brokers or a person or company having assets under administration with a value approaching that of an institutional investor that has access to and knowledge regarding the necessary technology to use direct electronic access. The Participant offering direct electronic access or a routing arrangement must establish sufficiently stringent standards for each client granted direct electronic access or each investment dealer or foreign dealer equivalent under a routing arrangement to ensure that the Participant is not exposed to undue risk and in particular, in the case of a non-institutional client the standards must be set higher than for institutional investors.
The Participant is further required to confirm with the client granted direct electronic access or an investment dealer or foreign dealer equivalent in a routing arrangement, at least annually, that the client, investment dealer or foreign dealer equivalent continues to meet the standards established by the Participant including to ensure that any modification to a previously “approved” automated order system in use by a client, investment dealer or foreign dealer equivalent continues to maintain appropriate safeguards.
Breaches by Clients with Direct Electronic Access or by Investment Dealers or Foreign Dealer Equivalents in a Routing Arrangement
A Participant that has granted direct electronic access to a client or entered into a routing arrangement with an investment dealer or foreign dealer equivalent must further monitor orders entered by the client, investment dealer or foreign dealer equivalent to identify whether the client, investment dealer or foreign dealer equivalent may have:
Identifying Originating Investment Dealer or Foreign Dealer Equivalent
In relation to the assignment of a unique identifier to an investment dealer or foreign dealer equivalent in a routing arrangement, if orders are routed through multiple investment dealers or foreign dealer equivalents, the executing Participant is responsible for properly identifying the originating investment dealer or foreign dealer equivalent and must establish and maintain adequate policies and procedures to assure that orders routed by an investment dealer or foreign dealer equivalent to the executing Participant containing the Participant’s identifier are also marked with all identifiers and designations relevant to the order as required under Rule 6.2 of UMIR on the entry of the order to a marketplace.
Identifying Clients with Direct Electronic Access
In relation to the assignment of a unique identifier to a client that is granted direct electronic access, the Participant must establish and maintain adequate policies and procedures to assure that orders routed by the client to the executing Participant containing the Participant’s identifier are marked with all identifiers and designations relevant to the order as required under Rule 6.2 of UMIR on the entry of the order to a marketplace.
Each Participant must develop, implement and maintain a supervision system to ensure that an accurate and complete audit trail of orders and trades under Rule 10.11 and Rule 10.12 is recorded and maintained.
At a minimum, policies and procedures regarding audit trail requirements must ensure the accurate recording of the following information for each order and trade as applicable:
Sample sets must be randomly selected to proportionately cover orders and trades related to all lines of business of a Participant. Reviews for compliance with Audit Trail Requirements must be carried out at least on a quarterly basis and reviews for compliance with Record Retention Requirements must be carried out at least annually.
Each Participant must develop, implement and maintain a supervision system to ensure that its trading does not violate order exposure requirements under Rule 6.3 or client priority requirements under Rule 8.1. Reviews for compliance with these provisions must at a minimum include:
Each Participant must review the order entry and trading described above at least quarterly.
Each Participant must develop, implement and maintain a supervision system to review securities:
Policies and procedures designed to monitor trading around Grey and Restricted list securities must consider:
Each Participant must review the trading described above on a daily basis.
Each Participant must develop, implement and maintain a supervision system to verify that appropriate trade disclosures are made on client confirmations. To comply with Corporation rules, such disclosures must include:
Each Participant must review a sample of trade confirmations at least on a quarterly basis.
Each Participant must develop, implement and maintain a supervision system to review NCIB-related trading to ensure:
Each Participant must review trading related to NCIBs described above at least quarterly.
Supervisory policies and procedures must also be designed to review trading related to sales from control blocks. Such reviews must be carried out as when determined necessary by the Participant and must include:

Regulatory History:
On April 13, 2012, the applicable securities commissions approved an amendment, effective October 15, 2012, to add section 6.5.
In accordance with section 6.1 of the Trading Rules, each marketplace shall set requirements in respect of the hours of trading to be observed by marketplace participants. Occasions may arise when a Participant may wish to make an agreement to trade as principal with a Canadian account, or to arrange a trade between a Canadian account and a non-Canadian account, outside of the trading hours of any marketplace that trades the particular security.
Rule 6.4 states that all trades must be executed on a marketplace unless otherwise exempted from this requirement. Participants are reminded of the exemption in clause (2)(d) of Rule 6.4 that permits a trade on a foreign organized regulated market. Participants are also reminded of the exemption in clause (2)(e) of Rule 6.4 that permits them to trade as principal with non-Canadian accounts off of a marketplace provided that any unwinding trade with a Canadian account is made in accordance with Rule 6.4.
A Participant may make an agreement to trade in a listed security or a quoted security with a Canadian account as principal or as agent outside of the trading hours of marketplaces, however, such agreements must be made conditional on execution of the trade on a marketplace or on a foreign organized regulated market. There is no trade until such time as there is an execution on a marketplace or a foreign organized regulated market or the trade is otherwise completed in accordance with one of the exemptions set out in Rule 6.4. The trade on a marketplace is to be done at or immediately following the opening of the marketplace on which the order is entered. A Participant may cross the trade at the agreed-upon price provided that the normal Requirements on order displacement are followed. If the Participant determines that the condition of recording the agreement to trade on a marketplace or foreign organized regulated market cannot be met, the agreement to trade shall be cancelled. Use of an error account to preserve the transaction is prohibited.
The Market Regulator considers that any use by a Participant of another person that is not subject to Rule 6.4 in order to make a trade off of a marketplace (other than as permitted by one of the exemptions) to be a violation of clause (a) of subsection (2) of Rule 2.1 respecting specific unacceptable activities.
Although certain affiliated entities of a Participant, including their foreign affiliates, are not directly subject to Requirements, Rule 6.4 means that a Participant may not transfer an order to a foreign affiliate, or book a trade through a foreign affiliate, and execute the order in a manner that does not comply with Rule 6.4. In other words, an order directed to a foreign affiliate by the Participant or any other person subject to Rule 6.4 shall be executed on a marketplace unless one of the exemptions set out in Rule 6.4 applies. Foreign branch offices of a Participant are not separate from the Participant and as such are subject to Requirements.
Clause (2)(e) of Rule 6.4 permits a Participant to trade off of a marketplace either as principal with a non-Canadian account or as agent for the purchaser and seller both of whom are non-Canadian accounts. A "non-Canadian account" is defined as an account of a client of the Participant or a client of an affiliated entity of the Participant held by a Participant or an affiliated entity of a Participant and the client is considered to be a non-resident for the purposes of the Income Tax Act (Canada). There may be certain situations arising where a Participant is uncertain whether a particular account is a "non-Canadian account" for the purpose of this exemption. In these situations the account should be treated as a “Canadian account”. The fact that an individual may be located temporarily outside of Canada, that a foreign location is used to place the order or as the address for settlement or confirmation of the trade does not alter the account's status as a Canadian account. Trades made by or on behalf of bona fide foreign subsidiaries of Canadian institutions are considered to be non-Canadian accounts, if the order is placed by the foreign subsidiary.
For the purpose of this Policy, the relevant client of the Participant is the person to whom the order is confirmed.
Clause (2)(e) of Rule 6.4 requires a Participant to report to a marketplace any trade in a listed security or a quoted security that is made as principal with a non-Canadian account or as agent if both the purchaser and seller are non-Canadian accounts, unless the trade is reported to a foreign organized regulated market. If such an “outside Canada” trade has not been reported to a foreign organized regulated market, a Participant shall report such trade to a marketplace no later than the close of business on the next trading day. The report shall identify the security, volume, price (in the currency of the trade and in Canadian dollars) and time of the trade.
Under Rule 6.4, a Participant, when acting as principal or agent, may not trade nor participate in a trade in a security by means other than the entry of an order on a marketplace except in accordance with an exemption specifically enumerated within Rule 6.4. For the purposes of UMIR, a “marketplace” is defined as an Exchange, QTRS or an ATS and a “Participant” is defined essentially as a dealer registered in accordance with securities legislation of any jurisdiction and who is a member of an Exchange, a user of a QTRS or a subscriber to an ATS. If a person is a Participant, certain provisions of UMIR will apply to every order handled by that Participant even if the order is entered or executed on a marketplace that has not adopted UMIR as its market integrity rules or if the order is executed over-the-counter. In particular, the following provisions of UMIR and the Corporation Rules will apply to an order handled by a Participant notwithstanding that the order is not entered on a marketplace that has adopted UMIR:
In accordance with Rule 11.9, UMIR will not apply to an order that is entered or executed on a marketplace in accordance with the Marketplace Rules of that marketplace as adopted in accordance with Part 7 of the Trading Rules or if the order is entered and executed on a marketplace or otherwise in accordance with the rules of an applicable regulation services provider or in accordance with the terms of an exemption from the application of the Trading Rules.
If a trade is to be executed on a foreign organized regulated market in a foreign currency, the foreign trade price shall be converted to Canadian dollars using the exchange rate the Participant would have applied in respect of a trade of similar size on a foreign organized regulated market in that foreign jurisdiction in order to determine whether the condition in subsection (3) of Rule 6.4 restricting avoidance of Part 6 of the Trading Rules has been met. The Market Regulator regards a difference of one trading increment or less as "marginal" because the difference would be attributable to currency conversion. A Participant shall maintain with the record of the order the exchange rate used for the purpose of determining whether a better priced order existed on a marketplace and such information shall be provided to the Market Regulator upon request in such form and manner as may be reasonably required by the Market Regulator in accordance with subsection (3) of Rule 10.11.

Rule 6.3 requires a Participant to immediately enter client orders for the purchase or sale of 50 standard trading units or less on a marketplace. This requirement is subject to certain exceptions. The Participant may withhold the order based on a determination that market conditions were such that immediate entry of the order would not be in the best interests of the client. If the order is withhold the Participant must guarantee that the client receives a price at least as good as the price the client would have received had the client order been executed on receipt by the Participant. If the order is executed against a principal order or non-client order the client must receive a better price.
Pursuant to Rule 6.3, a Participant may withhold entry of the order and return the order to its source for confirmation of its terms. For example, a Participant who receives an order to sell a security at $3 in a stock trading at $20 may return the order to the branch, as it is likely that either the price or the stock symbol is wrong.
A Participant does not have to immediately enter a client order on a marketplace if the client has requested that the order be withheld (for example, the client does not want the order executed in the open market but wishes to do a tax-related trade with their spouse). Any request must be specific to that order. A client cannot give a blanket request to withhold any future orders the client may give the Participant. Furthermore, the Participant may not solicit a request to withhold the order. A Participant must keep a record of the client’s request to withhold orders for seven years from the date of the instruction and, for the first two years, the request must be kept in a readily accessible location.

Rule 5.3 restricts a Participant and its employees from trading in the same securities as a client of the Participant. The restriction is designed to minimize the conflict of interest that occurs when a Participant or its employee compete with the firm’s clients for execution of orders. The Rule governs:
The application of the rule can be quite complex given the diversity of professional trading operations in many firms, which can include such activities as block facilitation, market making, derivative and arbitrage trading. In addition, firms may withhold particular client orders in order to obtain for the client a better execution than the client would have received if the order had been entered directly on a marketplace. Each firm must analyze its own operations, identify risk areas and adopt compliance procedures tailored to its particular situation.
A Participant has overriding agency responsibilities to its clients and cannot use technical compliance with the rule to establish fulfillment of its obligations if the Participant has not otherwise acted reasonably and diligently to obtain best execution of its client orders.
A Participant can never intentionally trade ahead of a client order that is either a market order or tradeable limit order received prior to the entry of the principal order or non-client order except in accordance with an exemption from the requirements of Rule 5.3(1), which exemptions include obtaining the specific consent of the client. Examples of "intentional trades” include, but are not limited to:
The Participant must have reasonable procedures in place to ensure that information concerning client orders is not used improperly within the firm. These procedures will vary from firm to firm and no one procedure will work for all firms. If a firm does not have reasonable procedures in place, it cannot rely on the exceptions. Reference should be made to Policy 7.1 – Policy on Trading Supervision Obligations, and in particular Part 4 – Specific Procedures Respecting Client Priority.
If a client has instructed a Participant to withhold an order or has granted a Participant discretion with respect to the entry of an order, details of the instruction or grant of discretion must be retained for a period of seven years from the date of the instruction or grant of discretion and, for the first two years, the consent must be kept in a readily accessible location.
A Participant does not have to provide priority to a client order if the client specifically consents to the Participant trading alongside or ahead of the client. The consent of the client must be specific to a particular order and details of the agreement with the client must be noted on the order ticket. A client cannot give a blanket form of consent to permit the Participant to trade alongside or ahead of any future orders the client may give the Participant.
If the client order is part of a pre-arranged trade that is to be completed at a price below the best bid price or above the best ask price as indicated on a consolidated market display, the Participant will be under an obligation to ensure that “better-priced” orders on a protected marketplace are filled prior to the execution of the client order. Prior to executing the client order, the Participant must ensure that the client is aware of the better-priced orders and has consented to the Participant executing as against them in priority to the client order. The consent of the client must be noted on the order ticket.
If the client has given the Participant an order that is to be executed at various times during a trading day (e.g. an “over-the-day” order) or at various prices (e.g. at various prices in order to approximate a volume-weighted average price), the client is deemed to have consented to the entry of principal orders and non-client orders that may trade ahead of the balance of the client order. Unless the client has provided standing written instructions that all orders are to be executed at various times during the trading day or at various prices during the trading day, the client instructions should be treated as specific to a particular order and the details of the instructions by the client must be noted on the order ticket. However, if the un-entered portion of the client order would reasonably be expected to affect the market price of the security, the Participant may be precluded from entering principal orders or non-client orders as a result of the application of the frontrunning rule.
In certain circumstances, a client may provide a conditional consent for the Participant to trade alongside or ahead of the client order. For example, a client may consent to a principal order of Participant sharing fills with the client order provided the client order is fully executed by the end of the trading day. If the client's order is not fully executed, the client may expect that the Participant "give up" its fills to the extent necessary to complete the client order. In this situation, the Participant should mark its orders as "principal" throughout the day. Any part of the execution which is given up to the client should not be re-crossed on a marketplace but should simply be journalled to the client (since the condition of the consent has not been met, the fills in question could be viewed as properly belonging to the client rather than the principal order). To the extent that a Participant "gives up" part of a fill of a principal order to a client based on the conditional consent, the Participant shall report the particulars of the "give up" to the Market Regulator not later than the opening of trading on marketplaces on the next trading day. The conditional consent of the client must be specific to a particular order. The details of the agreement with the client must be noted on the order ticket.
