What the option chain shows
GIFT Nifty is trading at +0.39% (+91.7 points) in the pre-market window, signaling a mild positive handoff as the cash Nifty prepares for expiry settlement. The prior session (Monday) closed with strong momentum—Nifty rallied 1.654% (+381.4 points) and Sensex gained 1.629% (+1,213.27 points)—keeping both indices well above their intraday pivot support levels heading into this session.
Nifty faces expiry today with zero days remaining on the contract, so all positioning will resolve at or before the open. Sensex, by contrast, carries two days to expiry, offering a window for rollover or fresh positioning. India VIX sits at 15.5, reflecting subdued option volatility despite the overnight gap and Monday's sharp rally.
Bias and readiness
On the Nifty side, chart support anchors at 23,284.97 and resistance at 23,518.72—a range of under 234 points. The open-interest support cluster at 23,000 and resistance at 24,000 have both seen fresh Addition over the most recent candle, suggesting that option players are actively building positions at both strikes ahead of expiry settlement. This two-way OI build indicates hedging and protective demand rather than a one-directional flush.
Sensex paints a wider technical picture: support at 75,216.34, resistance at 75,931—roughly 715 points of range. The OI map shows support at 73,000 and resistance at 77,000, considerably further from spot than Nifty's strikes. Both support and resistance in Sensex have logged Addition, mirroring the Nifty pattern. With two days to expiry on the Sensex contract, traders are laying groundwork rather than closing out.
Levels to watch
Five-day average daily moves clock 245 points for Nifty and 773 points for Sensex. Monday's 381-point gain on Nifty sits above that average, and Sensex's 1,213-point move is well above its norm, so the question for this session is whether momentum sustains or consolidates after such a sharp prior-day rally.
The GIFT gap and the two-way OI addition at both strikes suggest participants are preparing for expiry execution and potential rollover, rather than a decisive trending day. Watch how the open handles the 91-point overnight signal and whether option writers at 24,000 (Nifty) and 77,000 (Sensex) defend their resistance strikes.
