What are the different types of limit orders?

GTC (Good-Till-Canceled): Suitable for placing orders for long-term position holding and waiting for execution at a specific price. For example, if you think a certain price is a suitable entry/exit point, you can place this type of order and wait for execution.

Maker Only: Suitable for scenarios where you want to earn the Maker fee (0.02%) and do not want to execute as a Taker, which can avoid slippage losses. Your order will be executed as a Maker. If the system detects that the order will be matched as a Taker, the order will be automatically canceled.

IOC (Immediate or Cancel): The order will be prioritized for execution as a Maker, and any unexecuted portion will be canceled immediately; if it cannot be executed as a Maker, the order will attempt to execute a portion as a Taker, with the unexecuted portion canceled automatically. Suitable for scenarios where you want to execute part of the order as soon as possible and do not want the order to be listed for a long time.

FOK (Fill or Kill): The order must be fully executed immediately, otherwise the entire order will be completely canceled, and partial execution is not supported. Suitable for scenarios where you need to execute the entire order at one time and do not accept partial execution.
