What the option chain shows
GIFT Nifty has opened with a +137.75-point gap (+0.569%), signalling an attempt to reverse Wednesday's decline across both indices. Nifty fell 127.52 points (−0.524%) on the prior session while Sensex shed 183.27 points (−0.236%), a sharper percentage move despite the smaller point loss. The recovery signal now hinges on whether cash-market participants can sustain the overnight momentum.
India VIX sits at 10.57, reflecting the relatively subdued volatility environment. With five days remaining until Nifty expiry and zero days for Sensex—meaning Thursday's close marks final settlement for the index—the expiry calendar creates asymmetric dynamics between the two benchmarks. Sensex enters its last trading day, which typically concentrates positioning into final prints, while Nifty still carries five-day liquidity.
Bias and readiness
On the chart, Nifty's support sits at 24150.8 with resistance overhead at 24321.65. The options chain shows OI support at 24200 undergoing unwinding, suggesting some long liquidation at lower strikes, while resistance OI at 24500 is seeing fresh addition—a split signal that leaves the intermediate bias unsettled. Five-day average moves for Nifty stand at 143.3 points, only slightly larger than the overnight gap.
Sensex support via options sits at 77000, where OI activity is showing fresh addition. Resistance clusters at 78000, also attracting new positioning. Chart-level support and resistance span 77301.64 to 77815.54, bracketing a narrower range than Nifty's proportionally. The 5-day average daily move of 432.41 points provides context for likely intraday swings into expiry close.
Levels to watch
The divergence in expiry timing—Sensex closing out today while Nifty rolls forward—means Sensex settlement will crystallise Friday morning positions. Options flow shows resistance OI building on both indices, suggesting participants are hedging or adding short exposure above current levels. Support unwinding in Nifty contrasts with fresh support addition in Sensex, hinting that dealers may be reshaping gamma differently between the two as expiry approaches. The overnight gap recovery attempt meets a VIX backdrop that leaves room for either consolidation or controlled range trading into the cash open.
