Difficulty: HardTypes of Orders and Order Execution Strategies

Match each specialized order type or time-in-force instruction on the left with its precise execution rule and trigger condition on the right.

  • Fill-or-Kill (FOK)Must be executed immediately in its entirety at the specified price or better; if the entire quantity cannot be filled, the order is canceled completely.
  • Immediate-or-Cancel (IOC)Must be executed immediately at the specified price or better; partial fills are permitted, and any remaining unexecuted portion is canceled.
  • Market-on-Close (MOC)Executed as close to the official market closing price as possible; must be submitted prior to designated exchange cutoff times to ensure entry.
  • Buy Stop-Limit OrderEntered above the current market price; becomes a conditional order to buy at the limit price or better once activated by a trade or bid at or above the trigger price.

Answer

Fill-or-Kill (FOK) pairs with the requirement for immediate complete execution without partial fills. Immediate-or-Cancel (IOC) pairs with the requirement for immediate execution that permits partial fills and cancels any residual quantity. Market-on-Close (MOC) pairs with execution targeted at the closing price subject to entry deadline cutoffs. Buy Stop-Limit Order pairs with being entered above the market price and converting to a limit order upon trigger activation.
Each order instruction fulfills a distinct function: Fill-or-Kill requires immediate 100% execution or total cancellation; Immediate-or-Cancel requires immediate execution but accepts partial fills; Market-on-Close targets the session closing price subject to deadline rules; and a Buy Stop-Limit is placed above current market price, converting to a limit order once activated by a trade or bid at or above the stop price.

Step-by-Step Solution

1
Analyze Fill-or-Kill (FOK) vs Immediate-or-Cancel (IOC) execution rules.
FOK requires complete immediate execution (no partial fill), whereas IOC permits partial execution immediately and cancels the unfilled balance.
Differentiating between time-in-force qualifiers that allow partial fills versus those requiring all-or-none completion.
2
Analyze Market-on-Close (MOC) mechanics.
MOC orders target execution near the market close and are bound by exchange cutoff rules.
Assessing market execution instructions tied to specific trading session intervals.
3
Analyze Buy Stop-Limit placement and activation criteria.
Buy stop orders are entered above the current market price and convert into limit orders upon reaching or exceeding the stop price.
Understanding order entry placement relative to current market price and subsequent order conversion post-trigger.
