Order Book Elasticity

Order book elasticity measures how sensitive the order book is to changes in price. A highly elastic order book sees a significant influx of new orders when the price moves, which acts as a stabilizer and prevents extreme volatility.

Conversely, an inelastic order book lacks this responsive liquidity, leading to large price jumps even on small trade sizes. Market makers play a key role in providing this elasticity by adjusting their quotes in response to market activity.

Understanding this concept helps traders anticipate how the market will react to large orders or news events. It is a core component of market microstructure analysis, helping to quantify the stability and depth of a trading venue.
