NSE & BSE Indices Futures and Options Open Interest Volume Analysis for 13/08/2025

The Open Interest Volume Analysis for 13th August 2025 points to a market trying to carve out a base after recent volatility, with cautious optimism returning among traders. Nifty August futures climbed 0.64% to 24,712.20, outpacing spot gains, while open interest dipped 1% and futures premium leapt over 25 points—vividly reflecting short covering and fresh hedging as bears book profits. Options data backs this sentiment: the weekly Put-Call Ratio (OI) spiked sharply to 1.08, indicating increased put writing at 24,600 and a sturdy options-led support for expiry, with max pain holding steady at that level. Yet, the monthly options chain still leans neutral-to-cautious with the PCR just under 0.93 and dominant open interest crowding the 25,000 call and 24,000 put strikes, showing that traders are still wary of chasing the index higher without fresh positive cues.

BankNifty reinforced this cautious tone. The August future rose a modest 0.26% with a 1.5% OI uptick—evidence of tentative long buildup—but max pain at 55,600 and call-heavy resistance at 57,000 continue to anchor the index. FINNIFTY and MIDCPNIFTY also posted healthy gains (0.4% and 1.16% respectively), with FINNIFTY seeing notable fresh OI addition and midcaps showing the highest Put-Call Ratio improvement, hinting at a slow return of risk appetite in select pockets. SENSEX futures and options echoed Nifty’s script, closing up 0.4% on the day, as the PCR (OI) for its weekly expiry bounced above 1.0 and open interest declined—pointing again to short covering and expiry-linked repositioning.

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

This session’s Open Interest Volume Analysis suggests that after days of pressure, Indian markets may be stabilizing with some early signs of a short covering rally. For Nifty, the 24,600 level—where max pain and the highest put open interest converge—remains the critical expiry pivot. If this support holds and OI continues to drop while price rises, a move up toward the heavy resistance at 24,900–25,000 is possible, though upward progress will likely slow amid thick call OI and persistent caution. For BankNifty, a sustained move above 55,600 with an OI build would signal growing confidence; otherwise, sideways-to-choppy action remains likely. FINNIFTY and MIDCPNIFTY are showing improving risk sentiment—nimble traders might look for selective long trades in midcaps or iron condors/spreads around existing max pain levels for limited risk.

Actionable strategy: focus on range-based and hedged trades, such as credit put spreads or straddles around 24,600 for Nifty; avoid all-or-nothing directions until open interest or volume patterns confirm a decisive trend. Keep tight stops and dial up risk management, letting this Open Interest Volume Analysis steer trades through expiry volatility as markets seek firmer ground.
