The correct answer is D . Under UMIR 1.1, a market order is an order to buy a security or derivative that is executed upon entry to a marketplace at the best ask price , or an order to sell that executes at the best bid price . This is essentially the wording used in D.
Unlike a limit order, a market order does not establish a maximum purchase price or minimum sale price. Its priority is prompt execution against the best available displayed liquidity, although the ultimate execution price can vary if available volume at the best price is insufficient.
Each other option describes a different recognized order type. A is a bundled order , defined by UMIR as an order combining a client order with a non-client or principal order, or both. B describes a limit order , because the purchaser specifies the maximum acceptable execution price. C describes a Closing Price Order , which is entered subject to execution at the security's closing sale price.
The CIRE syllabus expressly requires candidates to understand different order types, including market orders, limit orders, immediate-or-cancel orders, fill-or-kill orders, on-stop orders and iceberg orders .
