Overview
Day-over-day change in total aggregate futures open interest, measured in USD. Positive values indicate net new positions being opened across exchanges; negative values indicate positions being closed or liquidated.
Interpretation
Large positive spikes (>1B) indicate mass liquidation events or coordinated position unwinding, which typically occur during sharp price drops. Moderate daily changes (500M) reflect normal market activity. Sustained positive deltas over multiple days signal growing conviction and leverage buildup.
Use Cases
- Detecting leverage events and liquidation cascades in real-time
- Timing entries around position flushes (large negative deltas)
- Monitoring market participation changes day-over-day
- Building quantitative signals based on OI momentum
