Multiple empirical studies have shown that Order Flow Imbalance has predictive power over the trading range.
The PIN Theory (Easley et al. ) reveals the Microstructure mechanism by which:
– Market Makers adjust their trading range to avoid being adversely selected by Informed Traders.
– Informed Traders reveal their future trading intentions when they alter the Order Flow.
– Consequently, Market Makers’ trading range is a function of the Order Flow imbalance.
VPIN is a High Frequency estimate of PIN, which can be used to detect the presence of Informed Traders, monitor liquidity conditions and forecast microstructural volatility.
