Open Interest Analysis: How to Read OI Changes in Crypto
Open interest reveals what price alone can't tell you: whether moves are driven by new money entering or existing positions liquidating. Master OI analysis for smarter trades.
- Open interest (OI) measures total outstanding contracts—rising OI means new positions, falling OI means positions closing.
- Combine OI direction with price direction to understand if moves are conviction-driven or liquidation-driven.
- Thrive tracks OI changes and alerts you when they signal important market shifts.

Signal
bullish
New money entering the market on the long side. Fresh longs being opened as price rises. This is healthy trend confirmation—buyers have conviction and are adding positions. The uptrend is being fueled by new capital.
Bullish continuation signal. Look for pullback entries to join the trend. The rising OI supports the move—this isn't just short covering. Trail stops as trend continues.
What Is Open Interest?
Open interest is the total number of outstanding derivative contracts. In crypto perpetuals and futures, each position has both a long and a short side. When someone opens a new long, someone else opens a new short—OI increases by one contract. When positions are closed, OI decreases.
Key insight: OI measures how much capital is committed to the market. Rising OI = new money entering. Falling OI = money exiting. This is different from volume, which just measures contracts traded regardless of whether positions are opening or closing.
OI vs Volume: Key Differences
Volume and OI measure different things. High volume with flat OI means positions are changing hands—existing longs selling to new longs. High volume with rising OI means genuine new interest—new longs and shorts entering.
- High volume + rising OI: Strong conviction. New money entering on both sides.
- High volume + flat OI: Position rotation. Existing positions changing hands.
- High volume + falling OI: Position closing. Liquidations or voluntary exits.
- Low volume + any OI: Quiet market. Low interest in current price levels.
| Price | OI | Volume | Interpretation |
|---|---|---|---|
| ↑ Up | ↑ Rising | High | New longs entering—bullish conviction |
| ↑ Up | ↓ Falling | High | Short covering—weaker bullish signal |
| ↓ Down | ↑ Rising | High | New shorts entering—bearish conviction |
| ↓ Down | ↓ Falling | High | Long liquidations—capitulation signal |
| → Flat | ↑ Rising | High | Tension building—breakout imminent |
Reading OI + Price Combinations
Price Up + OI Up: New Money Long
The healthiest bullish signal. Fresh capital entering long side. Buyers have conviction—they're opening new positions, not just covering shorts. Trend likely to continue while this dynamic holds.
Price Up + OI Down: Short Covering
Price rising but positions closing—shorts are being squeezed out. This is liquidation-driven, not conviction-driven. Once short covering exhausts, the rally may stall. Less sustainable than new buying.
Price Down + OI Up: New Money Short
Fresh capital entering short side. Sellers have conviction—they're opening new positions. Trend likely to continue while this dynamic holds. Aggressive selling pressure.
Price Down + OI Down: Long Liquidations
Longs being liquidated or voluntarily exiting. This is capitulation/deleveraging. Once long liquidation exhausts, selling pressure may ease. Watch for OI to stabilize—potential bottom signal.
Trading OI Extremes
Elevated OI means heavy positioning—and liquidation risk. When lots of leverage is in the system, price moves get amplified by cascading liquidations.
- High OI at support: If support breaks, long liquidations will accelerate the drop.
- High OI at resistance: If resistance breaks, short liquidations will fuel the rally.
- OI ATH + extended price: Market is very leveraged. Be cautious—either direction could trigger cascades.

Combining OI with Funding
OI tells you how much is positioned; funding tells you which side. High OI + high positive funding = crowded long. High OI + negative funding = crowded short.
- High OI + extreme positive funding: Crowded and expensive longs. High squeeze risk for longs.
- High OI + extreme negative funding: Crowded shorts paying to stay short. High squeeze risk for shorts.
- High OI + neutral funding: Heavy positioning but balanced. Both sides have conviction.
Common OI Analysis Mistakes
- Looking at OI alone: OI needs price context. Rising OI is bullish with rising price, bearish with falling price.
- Ignoring exchange differences: OI varies by exchange. Aggregate across major venues for full picture.
- Conflating OI and volume: They measure different things. High volume doesn't mean high OI change.
- Short-term noise: Hourly OI changes can be noisy. Focus on 4H/daily trends for cleaner signals.
Frequently Asked Questions
What is open interest in crypto?
Open interest (OI) is the total number of outstanding futures or perpetual contracts that have not been settled. Each contract has both a long and short side. OI increases when new positions are opened and decreases when positions are closed.
How is open interest different from volume?
Volume measures total contracts traded in a period. OI measures contracts currently held. Volume can be high with flat OI (positions changing hands). Rising OI means new positions are being opened; falling OI means positions are being closed.
What does rising OI with rising price mean?
Rising OI + rising price indicates new money entering long positions—bullish. Fresh capital is being committed to the upside. This is healthier than price rising on short covering (falling OI), which suggests conviction.
What does falling OI with falling price mean?
Falling OI + falling price indicates longs are being liquidated or voluntarily closing. This is deleveraging/capitulation. Once long liquidation exhausts, selling pressure may ease—potential bottom signal when OI stabilizes.
What is an OI divergence?
OI divergence occurs when price and OI move in opposite directions. Price up + OI down = short covering (weaker signal). Price down + OI down = long liquidation. Price flat + OI up = tension building (breakout imminent).
How do I use OI for trade entries?
Use OI to confirm moves. Rising OI confirms trend strength. Falling OI suggests move is liquidation-driven and may exhaust. High OI at levels = liquidation risk. Combine OI analysis with funding rate and price action.
What does very high OI mean?
Elevated OI means the market is heavily positioned—there's a lot of leverage in the system. High OI creates liquidation risk: when price moves sharply, cascading liquidations amplify the move. Be cautious at OI extremes.
Where can I find open interest data?
Most exchanges show OI on their trading interfaces. Aggregated data is available on Coinglass, CoinGecko, and analytics platforms. Thrive tracks OI changes and alerts you to significant shifts automatically.
