Order Book Elasticity Coefficient

Calculation

The Order Book Elasticity Coefficient quantifies the sensitivity of price impact to order size within a limit order book, providing insight into market liquidity conditions. It’s derived from the slope of the price-impact curve, representing the proportional change in price resulting from a unit change in order volume. This coefficient is particularly relevant in cryptocurrency markets due to their fragmented liquidity and susceptibility to rapid price swings, informing algorithmic trading strategies and risk assessments. Accurate calculation requires high-frequency data and careful consideration of order book depth and spread.
