What Is the Concept of “Hidden Liquidity” in an Order Book?

Hidden liquidity refers to order volume that is not immediately visible in the public order book. This is often achieved through "iceberg orders," which are large orders broken into smaller visible parts.

While the full depth is not seen, the presence of these large hidden orders suggests a higher true market depth than appears, which can reduce slippage risk for large incoming market orders.
