An institutional-sized client order contains 100,000 shares, but the client wants only 5,000 shares displayed...

An iceberg order displays only a specified portion of a larger order while keeping the remaining quantity undisclosed. As the displayed portion is executed, additional shares from the reserve quantity may become visible according to marketplace rules. Option A is correct.

In this scenario, the order can contain 100,000 shares while displaying only 5,000 at a time. Limiting displayed size may reduce information leakage and the risk that other market participants react adversely to a visibly large buying or selling interest. However, the hidden quantity does not guarantee execution or prevent the market from inferring that a larger order exists.

A fill-or-kill order requires immediate execution of the full quantity or cancellation. A market-on-open order seeks execution during the opening process. A sell on-stop order activates after a specified trigger price is reached. None provides the requested partial-display feature.

Iceberg orders must be used for legitimate execution purposes. Using displayed or partially displayed orders to detect another participant’s hidden liquidity and then trade ahead can create market-integrity concerns. CIRO’s current guidance recognizes that abusive liquidity-detection strategies may be manipulative.

The Retail Securities syllabus specifically includes iceberg orders among the order types candidates must apply to client requirements.
