Fill or kill
Fill or kill means the whole order must be filled immediately, or none of it is.
Explanation
MetaTrader 5's fill policy says a fill-or-kill order can be filled only in the specified volume. If that volume is not available, the order is not executed. The volume may be made up of several offers. CME's definition adds a price condition: the order is cancelled if it is not immediately filled for the total quantity at the specified price or better. The two specifications match on the all-or-nothing point and differ in the words they use about price. A retail platform offers the policy only in the execution modes its help table allows. Instant and request execution on MetaTrader 5 list fill or kill, not immediate or cancel.
