Overview
Day-over-day percentage change in total aggregate futures open interest. This normalizes the absolute USD change for comparability across different market conditions and OI levels.
Interpretation
Values above +5% indicate aggressive position building — often seen before major breakouts or before liquidation-driven reversals. Values below -5% signal mass unwinding or forced liquidations. During range-bound markets, daily changes typically stay within plus or minus 2%. Extended periods of positive percentage changes suggest sustained leverage buildup, which increases fragility and the risk of cascading liquidations.
Use Cases
- Comparing leverage changes across different market regimes regardless of absolute OI level
- Building OI momentum indicators and divergence signals
- Identifying periods of abnormal position activity
- Creating alerts for potential liquidation risk when sustained high positive values are observed
