Can a Trade Execution Result in Zero Slippage, and What Are the Conditions?

Yes, zero slippage occurs when the executed price is exactly the same as the expected price at the moment the order was placed. This is most likely to happen in highly liquid markets with tight bid-ask spreads, low volatility, and when using a small order size relative to the available liquidity.

A limit order that is filled exactly at the limit price also results in zero slippage. In reality, zero slippage for market orders is rare, especially in volatile crypto or derivatives markets.
