Iceberg
What is an Iceberg Order?
Iceberg orders are large single orders that have been divided into smaller limit orders, for the purpose of hiding the actual order amount. The term "iceberg" comes from the fact that the visible lots are just the [tip of the iceberg] given the greater number of limit orders ready to be placed. Iceberg orders are usually placed to avoid disrupting trading markets with a single, large order and increasing costs.
Iceberg Order User Guide
If you want to buy 100 BTC when its price falls to 100,000 USDT and you don't want to disrupt the trading market and increase costs with such a single and large order, you can check the [Iceberg] box in placing a limit order and you can customize the visible amount, that is the displayed amount of buy orders on the order book. Then you can click [Buy BTC] to place the orders. All orders will be gradually executed after the first order is filled.

IOC (Immediate Or Cancel)
What is IOC?
Enabling IOC when placing an order means that any portion that is not immediately filled will be cancelled.
For example, you want to sell half of your BTC at the price of 20,000 USDT, but only 1/4 of the orders are immediately filled. In this case, if you have enabled IOC when placing the order, the portion that is not immediately filled will be cancelled.
When an investor place a large order and do not want to encounter large price differences, he or she can enable IOC when placing the order. Moreover, when an investor have placed orders of multiple trading pairs, enabling IOC can also avoid forgetting to cancel orders. Enabling IOC when placing a limit order can avoid orders being filled at an unsatisfying price when the market is volatile.
IOC User Guide
Suppose you want to buy 50 BTC when the BTC price reaches 111,000 USDT. Simply select [Advanced Limit] in the order placement area, choose [Immediate Or Cancel (IOC)] under Order Type, and confirm to use the IOC function.
How to View the Details of an IOC Order
