## Hidden Order Types

Hidden order types are special order instructions that allow traders to keep their order size or price level invisible in the public order book. These orders only become visible when they are executed against an incoming trade.

They are a powerful tool for large participants who wish to avoid revealing their full trading interest to the market. By using hidden orders, traders can prevent others from adjusting their quotes in response to the hidden liquidity.

However, they may also result in slower execution as they are often prioritized behind visible orders. Understanding when to use these types is a key skill for managing execution strategy.

They are a common feature in both centralized exchanges and some advanced decentralized platforms.
