Is the Change in Open Interest Revealing a Shift in Market Strength?
About the Change in Open Interest Structure
Change in Open Interest (OI) provides a real-time read of what participants are building or unwinding. Long build-up signals aggressive buying with rising prices while short build-up reflects selling pressure. Long unwinding and short-covering work as reversal signals, giving early alerts of directional exhaustion. This makes the OI change table one of the sharpest tools for decoding intraday and positional sentiment shifts.
The current OI change suggests a mixed structure: index futures are witnessing selective long unwinding at higher strikes and mild short-covering at supports. This hints that bulls are defending lower zones while bears continue to cap rallies near resistance clusters.
