NSE & BSE Indices Futures and Options Open Interest Volume Analysis for 30/07/2025

Table of Contents
The Open Interest Volume Analysis for 30th July 2025 reveals a textbook expiry-eve scenario—marked by sharp position squaring, range-bound price action, and market participants content to step aside ahead of a fresh monthly cycle. Nifty July futures eked out a modest 0.12% gain to 24,869.30, but the headline is the immense 23.5% drop in open interest and a nearly 18% volume decline, exposing a wholesale clean-out of positions rather than conviction-led moves. The premium further compressed to 14.25, underscoring a reluctance to extend risk in either direction.
Options data reflect the expiry tug-of-war: the Put-Call Ratio (OI) nudged up to 0.778 as both calls and puts saw heavy build-up at 24,900, establishing that level as the expiry magnet (max pain). While the sentiment has marginally improved from the previous day’s capitulation, call writers retain the upper hand at 25,000. This indecision and liquidation rhythm echo across BankNifty, FINNIFTY, and MIDCPNIFTY, each reporting striking double-digit OI drops and minimal directional movement—a market content to wait for July’s settlement before sparking fresh trends.

Conclusion: What the NSE & BSE Indices Futures and Options Open Interest Volume Analysis Tells Us
This session’s Open Interest Volume Analysis signals the classic expiry shakeout, but it leaves traders with valuable tactical cues. Nifty’s max pain at 24,900 is now the centre of gravity—expect expiry settlement to orbit closely around this strike barring an abrupt global disruption. With open interest sharply lower and both calls and puts crowding the same zone, the odds favor a low-volatility expiration, rewarding those who deployed iron condors or short straddles targeting 24,900.
Bulls should resist fresh longs until the series rolls and spot reclaims 25,000 on sustained volume, while bears may find better risk-reward only if settlement shows a clear breakdown under 24,800. In BankNifty and FINNIFTY, similar expiry magnet levels (56,200 and 26,700 respectively) merit attention, while midcaps remain especially sensitive to global cues as aggressive squaring dominates. Into the new series, let this Open Interest Volume Analysis be your trading compass—stay defensive, watch for new open interest to emerge and let cleaner option chains and volumes guide actionable trades in August.
