Open Interest Volume Analysis

The Open Interest Volume Analysis for 18th July 2025 paints a stark picture of persistent selling pressure and risk aversion. Nifty July futures slid 0.57% to 25,032.30, with open interest drifting down by 0.6%. This signals that traders continued unwinding positions as the index dropped below 25,000 for the first time this series. The slight uptick in the futures premium—despite the sell-off—suggests hedging, not bullish bets, and weak long hands exiting. Option activity underscores the bearish mood: the weekly Put-Call Ratio (OI) tumbled to just 0.588, driven by aggressive call writing at 25,100, while new puts clustered south at 23,050, highlighting a growing fear of deeper cuts. Monthly figures offer no respite, with PCR slipping to 0.92 and max pain anchored at 25,200 as both calls and puts shift lower. It’s a similar story across the board: BankNifty, FINNIFTY, and MIDCPNIFTY all closed deep in the red, with BankNifty’s open interest surging 4.8%—fresh shorts, not bargain hunters, are in control.

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

This session’s Open Interest Volume Analysis signals that the market is mired in a sell-on-rise regime, with every recovery swiftly met by call writing and new short builds. For Nifty, keep a sharp eye on the 25,000–25,100 range—if this zone fails to hold, a slide toward 24,800 or even 24,600 is likely, as option writers pull their hedges further down. Any upside will face stiff resistance at 25,300–25,500 due to accumulated call OI, so nimble traders might consider iron condors or ratio spreads to capitalize on rangebound volatility. In BankNifty, the 56,000–56,500 band is now a hard-fought floor; breaches could quickly escalate into sharper unwinding. Across sectors, watch for defensive rotation: FINNIFTY’s heavy OI drop hints at an exit from financials, while MIDCPNIFTY’s lighter selling suggests midcaps might be the first to stabilize if sentiment shifts. As expiry nears, let this Open Interest Volume Analysis guide tactical positioning—stick to short-the-rally trades while the tape stays heavy, but be ready to pivot fast if a short squeeze emerges on any positive macro signal.
