Long buildup and short buildup. OI buildup for every F&O stock, today.
Every NSE F&O stock and index sorted into long build-up, short build-up, short covering and long unwinding from today’s futures price change and change in open interest.
Data shows positioning. Your chart shows timing. ChartMine marks entries, stop-loss and targets on TradingView.
See plans →Price up with OI up is long build-up; price down with OI up is short build-up; price up with OI down is short covering; price down with OI down is long unwinding.
Open interest is added across all expiries, so traders rolling positions to the next month do not look like new or closed positions.
Fresh build-ups show where new money is committing; covering and unwinding show positions closing. Combine with price levels before acting.
From NSE’s end-of-day F&O files (bhavcopy and the MWPL file), published each evening after NSE posts them. Futures OI is summed across expiries so roll-overs do not look like new positions. Information, not investment advice.
