Market Microstructure Slippage
Slippage occurs when the executed price of a trade differs from the expected price at the time the order was placed, typically due to insufficient liquidity or high volatility. In cryptocurrency and derivative markets, this is a critical component of strategy profitability because large orders can move the market against the trader, especially in order books with thin depth.
It represents the cost of immediacy, where a trader pays a premium to have their order filled instantly rather than waiting for a better price. Market microstructure analysis focuses on the mechanics of the order book, bid-ask spreads, and how limit orders interact with market orders to create these price deviations.
Minimizing slippage is essential for high-frequency and large-scale trading strategies, as it directly erodes the theoretical alpha generated by the strategy.
