In addition to LMT orders, there are two types of orders for immediate execution on the TACT-Derivatives system:
Fill or Kill (FOK) orders – an order at a specific price, for full and immediate execution. An order not executed immediately and in full is cancelled and is not recorded in the order book.
Immediate or Cancel (IOC) orders – an order at a specific price, for immediate execution, even if partial. The order or part thereof not immediately executed is cancelled and is not recorded in the order book.
Orders are executed and prioritized based on the same principles as in the TACT Securities system.
Market (MKT) orders do not exist in TACT-Derivatives.
