What the option chain shows
Friday's session closed with modest upside across both indices, setting a calm tone ahead of the final trading week of August. Nifty rose 84.56 points (0.351%), while Sensex gained 329.28 points (0.428%), neither move dramatic but enough to extend the week's momentum. India VIX settled at 10.68, reflecting subdued volatility expectations as the market heads into expiry.
The proximity to index expiry creates a sharp contrast between the two benchmarks. Nifty has just one day remaining before options expire, whereas Sensex still carries three days, potentially explaining different tactical positioning in their respective chains. With Nifty's 5-day average daily move standing at 175.34 points and Sensex averaging 554.65 points, the coming sessions will test whether current quiet conditions persist or whether expiry mechanics inject fresh momentum.
Bias and readiness
On the options front, both indices are showing aggressive accumulation at support and resistance levels. Nifty's 24,000 put strike and 24,300 call strike have both seen open interest addition, suggesting market participants are actively layering hedges and directional bets simultaneously. The same dual-addition pattern appears in Sensex, with fresh open interest building at both the 75,000 support and 78,000 resistance strikes. This two-way buildup often reflects uncertainty or a prepared stance ahead of potential volatility events rather than a one-sided conviction.
Nifty's chart support sits at 24,105.57 against resistance at 24,217.02, a relatively tight 111-point band. Sensex shows wider breathing room, with support at 77,049.16 and resistance at 77,418.91. How price action respects these levels in early trade will signal whether the calm VIX environment holds or whether expiry-week mechanics begin to tighten ranges further.
Levels to watch
The absence of a GIFT Nifty gap—neither elevated nor depressed—suggests overnight global sentiment has remained balanced. For traders and participants watching this final expiry week, the key theme is option positioning readiness rather than directional conviction at this hour.
