FAQs

OI losers are futures or options contracts that have recorded the highest decrease in open interest during a session. Falling OI means existing contracts are being squared off - traders are closing (exiting) their positions.

Falling OI with a rising price = short covering (bearish traders exiting, can be bullish short term). Falling OI with a falling price = long unwinding (bulls exiting, bearish signal). Context with price direction is key.

Short covering occurs when traders who had sold (shorted) futures contracts buy them back to close their positions. This results in falling OI alongside a price rise and can cause a sharp upward price move.

Long unwinding happens when traders who held long (buy) futures positions sell them to exit. This results in falling OI alongside a falling price, indicating that bullish participants are losing conviction.

OI loser data reveals where large position unwinding is happening. When combined with price direction, it helps identify short covering rallies (opportunity to ride the upswing) or long unwinding (signal to reduce exposure).
