Liquidity-Adjusted Spread

Calculation

The liquidity-adjusted spread represents a refinement of the conventional bid-ask spread, incorporating a quantification of market depth to provide a more accurate representation of trading costs, particularly relevant in cryptocurrency derivatives. Its derivation involves assessing the price impact of executing a trade of a specified size, factoring in the available liquidity at various price levels, and subsequently adjusting the observed spread. This adjustment is crucial for evaluating the true cost of trading, especially for larger orders where slippage can significantly impact profitability, and is often used in algorithmic trading strategies. Accurate calculation requires high-resolution order book data and a robust model for estimating price impact.
