What Is a ‘Hidden Limit Order’ and Is It Compatible with Stop-Limit Functionality?

A hidden limit order, or 'iceberg order,' is a large limit order where only a small portion is displayed on the order book, while the rest remains concealed. This is used to prevent market front-running.

While exchanges may offer hidden limit orders, they are generally not compatible with the trigger mechanism of a stop-limit order, which requires the order to be inactive until the stop price is hit. However, the resulting limit order after the trigger may sometimes be placed as a hidden order, depending on the exchange's rules.
