Volume-Synchronized Probability of Informed Trading

Volume-Synchronized Probability of Informed Trading is a quantitative model used to estimate the presence of informed traders in a market based on trade volume and price changes. Unlike traditional models that use time-based intervals, this metric synchronizes data based on trading volume to better capture market activity spikes.

It provides a signal for the level of toxicity in the order flow, helping participants assess the risk of trading at current quotes. A high value indicates that a significant portion of the trading activity is driven by participants with private information, signaling potential price moves.

This model is widely used by quantitative researchers to calibrate liquidity provision strategies and manage execution risk. By focusing on volume rather than time, it provides a more accurate reflection of market microstructure dynamics during periods of high volatility.
