Order Imbalance Ratio

Calculation

The Order Imbalance Ratio quantifies the disparity between buy and sell order flow, representing a momentary excess of either buying or selling pressure within a specific market. It’s derived by subtracting the volume of sell orders from buy orders, then normalizing this difference by total order volume, providing a standardized metric for assessing directional imbalance. This ratio serves as a short-term indicator of potential price movement, particularly relevant in high-frequency trading and algorithmic strategies where rapid order flow analysis is critical. Accurate calculation requires access to level 2 market data, detailing the depth and composition of the order book.
