Order Book Imbalance Ratio

Calculation

The Order Book Imbalance Ratio quantifies the disparity between bid and ask side order volume within a defined price level, serving as a real-time indicator of potential short-term price movement. It’s derived by subtracting the total ask volume from the total bid volume, then normalizing this difference by the sum of both volumes, providing a value typically ranging from -1 to 1. A positive ratio suggests buying pressure dominates, while a negative ratio indicates selling pressure, influencing tactical trading decisions and algorithmic execution strategies. This metric is particularly relevant in cryptocurrency markets due to their fragmented liquidity and susceptibility to rapid shifts in order flow.
