The correct answer is B . Under CIRO's best-execution framework, Investment Dealers must maintain policies and procedures designed to achieve the most advantageous execution terms reasonably available for clients. IDPC Rule 3121 expressly identifies “the certainty of execution of the client order” as one of the broad best-execution factors that must be addressed.
For listed securities and listed derivatives, the prescribed broad factors are the price of the security or derivative, speed of execution , certainty of execution , and overall transaction cost where those costs are passed on to clients. Best execution therefore involves more than automatically selecting the apparently best displayed price; execution probability, liquidity, order size, market conditions, routing and transaction costs may affect the optimal handling of an order. CIRO guidance reinforces these four central factors.
A is incorrectly phrased because the regulatory factor is the price of the security or derivative in achieving execution , not the security's resulting market price after an order is placed. C confuses speed of reporting with speed of execution . D refers to the Dealer's own execution cost, whereas the rule focuses on overall transaction costs when passed on to the client .
The CIRE syllabus specifically includes best execution within its market-integrity learning outcomes.
