OI Delta

Track Open Interest changes per candle directly on the chart to see when new money enters and exits the market.

What is OI Delta?

OI Delta is a chart overlay that shows Open Interest changes for each individual candle, sourced from Hyperliquid on-chain data. Green bars indicate candles where Open Interest increased (new positions were opened), and red bars indicate candles where Open Interest decreased (positions were closed or liquidated).

While the OI Delta Heatmap gives you a market-wide view across many coins, this overlay focuses on a single asset and maps OI changes directly onto the price chart. This makes it easy to correlate Open Interest shifts with specific price action — you can see exactly which candles attracted new positioning and which ones saw exits.

Understanding OI Delta in context with price movement is one of the most powerful tools for reading market conviction. A move backed by rising OI has fundamentally different implications than the same move with declining OI.

Key Concepts

• OI Increasing (Green): New positions are being opened — fresh capital is entering the market during this candle
• OI Decreasing (Red): Positions are being closed — capital is leaving the market, either through voluntary exits or liquidations
• OI + Price Correlation: The relationship between OI direction and price direction reveals the nature and strength of a move
• Per-Candle Resolution: OI change is calculated for each individual candle, giving you precise timing on when positioning shifts occur

How to Use OI Delta

1. Open Chart from the sidebar and select the overlay settings
2. Enable the OI Delta overlay for the current symbol
3. Green bars appear on candles where OI increased; red bars where OI decreased
4. Bar height reflects the magnitude of the OI change
5. Correlate the OI bars with the price candles to read market conviction

What to Look For

• Bullish signals: Price rising with consistent green OI Delta bars means new long positions are driving the rally — this is strong, conviction-backed upside. Large green OI Delta during consolidation suggests positions are building ahead of a breakout.
• Bearish signals: Price rising with red OI Delta bars indicates short covering, not new buying — the rally lacks fresh capital and may exhaust. Price dropping with large green OI Delta means aggressive new short positions are piling in, adding persistent selling pressure.
• Key patterns: A sudden spike in OI at a key technical level often precedes a volatile move — many traders are taking positions at the same level, setting up a squeeze in one direction. Divergence between price trend and OI trend is a reliable warning signal: if price keeps rising but OI is flat or declining, the move is losing participation.
• Combine with: OI Delta Heatmap for the market-wide context on positioning, Liquidation Levels to see where the new positions would get force-closed, Trade Footprint for the actual buy/sell volume breakdown alongside the OI changes

Tips

• Always read OI Delta together with price direction — the combination tells a more complete story than either metric alone
• Sudden OI drops during a sharp price move usually indicate liquidations rather than voluntary exits — cross-reference with Liquidation Levels to confirm
• Pay special attention to OI behavior at key support and resistance levels — new positions opening at these levels signal that traders are committing capital to a directional bet
