Open interest measures the total value of outstanding futures positions. Rising open interest with rising price can indicate trend participation, but it can also mean leverage is building. When open interest spikes into euphoric moves, markets become fragile—small reversals can trigger forced unwinds and liquidations.
What this indicator is
The total outstanding futures/perpetual contracts (usually denominated in USD), used as a proxy for market leverage and positioning.
Why it matters
Open interest often leads volatility. High open interest increases the probability of liquidation cascades during sharp moves.
How to read it
- Green: Stable/open interest aligned with healthy spot demand.
- Yellow: Open interest rising quickly (leverage building).
- Red: Extreme open interest relative to trend (fragile market structure).
