Long Unwinding
Long unwinding is when price falls while open interest falls, as existing long holders book profits or exit.
When price declines and open interest also declines, it signals that longs are closing their positions — long unwinding — rather than new shorts piling in. It often reflects profit-booking or loss-cutting by bulls and can take momentum out of a prior uptrend.
Indian traders read long unwinding on the NSE as a sign that bullish conviction is fading, but it is less aggressively bearish than a fresh short build-up. Combining price and OI direction this way — across long build-up, short build-up, short covering, and long unwinding — is a core part of Indian F&O analysis.
