Open Interest Volume Analysis

The Open Interest Volume Analysis for 12th August 2025 shows that the recent bounce in Indian markets has lost steam, and downside risks are making a strong return. Nifty August futures closed at 24,554.90, slipping 0.30% while open interest ticked up 0.6% and the premium jumped over 24 points—a clear sign that sellers are back, building fresh short positions even as hedging bets push up premiums. Option data underscores the swing toward caution: the weekly Put-Call Ratio (OI) fell sharply to 0.65, reflecting heavy call writing at 24,700 and limited put support, with max pain locked at 24,500 for expiry. The monthly Put-Call Ratio (OI) also softened to 0.96, while the biggest additions gravitate around 24,600—showing market participants expect price action to remain under stress unless key supports hold.

BankNifty’s picture is no brighter. The index dropped 0.84%, open interest spiked 3%, and the premium widened sharply. Monthly BankNifty options saw the PCR (OI) dip to 0.70, with big call open interest at 57,000 and bulk put writing shifting to lower levels. Both FINNIFTY and MIDCPNIFTY mirrored these trends: heavy futures discounts, rising premiums, and falling PCRs signal that bears are squeezing the tape lower while buyers stay on the sidelines. SENSEX futures add a note of caution: a steep 42% jump in open interest and a large premium expansion mean institutional players are locking in protection—and brace for volatility—as the index heads toward expiry.

Conclusion: What the NSE & BSE Indices Futures and Options Open Interest Volume Analysis Tells Us

Today’s Open Interest Volume Analysis indicates that the market’s mood has taken a turn for the worse, with fresh shorts and aggressive call writing building a wall of resistance at every minor bounce. For Nifty, all eyes remain on the 24,500 area; failure to hold this level could trigger a deeper slide to 24,200 or even lower, as both option and futures data show little conviction for a reversal. Bulls should avoid chasing rallies until clear short covering emerges or put writers return in force.

Tactical traders may consider bear call spreads above 24,600 or iron condors around max pain, but always manage risk tightly. In BankNifty, FINNIFTY, and MIDCPNIFTY, the smart play is to stay nimble—stick with the trend or wait at the sidelines for clearer reversal signals, as the momentum still belongs to the bears. Let this Open Interest Volume Analysis guide your approach: prioritize capital protection, trade light, and let expiry levels and OI trends dictate direction as uncertainty reigns.
