Bearish positioning

How to read this. F&O positioning and the technical read are two separate lenses. Positioning (Long Buildup, Short Buildup, Short Covering, Long Unwinding) comes from how price and open interest moved together today — rising price with rising OI means fresh long positions. The technical read is StockLearn's chart verdict (Bullish, Caution, Weak). They can disagree: institutions often add longs before the chart confirms. When both agree, the signal is strongest — that's why we show them side by side rather than as one label.

Short Buildup. Price down + open interest up — fresh short positions being added (bearish positioning).

We sum open interest across all listed futures expiries for this underlying (near, next and far month), then compute OI % = change in OI ÷ previous OI × 100, where previous OI is yesterday's open interest (today's OI minus today's change). Exchange and broker pages usually show only the near-month future, so their near-month-only OI change can differ from this aggregate — for example when positions roll into the next expiry. Rollover % is the share of total futures OI sitting beyond the near month (1.97% here). It tends to rise through the expiry week as traders carry positions forward; a high or rising rollover signals positions being rolled rather than closed.
