1. Trading Volume vs. Open Interest
In derivatives analysis (futures and options), market participants evaluate two distinct liquidity and positioning metrics:
- Volume: The total number of contracts bought and sold during a specific trading session. Measures transactional activity and turnover.
- Open Interest (OI): The total number of outstanding active contracts that have not been settled, exercised, or closed. Measures aggregate institutional capital committed to the market.
2. Institutional Price & Positioning Matrix
| Price Trend | Open Interest | Market Character & Trend Strength |
|---|---|---|
| Rising | Rising | Strong Bull Trend: New money is aggressively entering the market on the long side. |
| Rising | Falling | Short Squeeze Rally: Price is rising solely because short sellers are covering; rally is fragile. |
| Falling | Rising | Strong Bear Trend: Aggressive new short positions are entering; aggressive institutional distribution. |
| Falling | Falling | Long Liquidation: Disillusioned bulls are closing losing positions; selling pressure likely near exhaustion. |
