Execution Probability Modeling

Execution Probability Modeling is the statistical estimation of the likelihood that a limit order will be filled at a specific price within a given timeframe. Market makers use these models to optimize their order placement and maximize their chances of capturing the spread.

By analyzing historical trade data and current order book dynamics, they can predict how price action will interact with their standing orders. This modeling is crucial for automated trading systems that need to place orders efficiently without overexposing themselves to unwanted risk.

It helps in determining the optimal distance from the mid-price to place orders to ensure high fill rates. High execution probability is a key factor in maintaining consistent liquidity and revenue for market makers.
