Nifty's options-derived support sits at 22000 and resistance at 24000 as of Friday, 23 October 2026, with spot at 22729. These levels come from open interest concentration: support is the strike with the heaviest put open interest below spot, and resistance the strike with the heaviest call open interest above spot — the levels where option writers have the largest positions, and therefore the strongest financial incentive to defend.
MarketCue's AI-Agentic platform tracks whether OI at each level is being added to or unwound, comparing the two most recently completed trading days. At support, the current read is "Support strengthening" — Addition means the floor is being reinforced with fresh contracts, while Unwinding means existing positions are being closed out, read as breakdown risk. At resistance, the read is "Resistance strengthening" — Addition strengthens the ceiling, while Unwinding suggests sellers are losing conviction there, a breakout signal.
This OI-based support/resistance read is one of four weighted inputs to MarketCue's Stage 1 Market Bias score, contributing 25% of the total when more than 3 days remain to expiry and rising to 45% — the single largest weight of any input — inside the last 3 days, when open interest positioning typically dominates price action into expiry.

Frequently asked questions
- How is Nifty support and resistance calculated from options data?
- MarketCue identifies support as the strike with the heaviest put open interest below spot, and resistance as the strike with the heaviest call open interest above spot -- the levels where option writers have concentrated the most contracts, and therefore have the strongest incentive to defend.
- What does OI "Addition" or "Unwinding" mean at a support or resistance level?
- "Addition" means fresh open interest is being built at that strike compared to the prior session, strengthening the level. "Unwinding" means existing open interest is being closed out, weakening the level -- at support, that reads as breakdown risk; at resistance, as breakout risk.
- Do options-based support and resistance levels change during the day?
- Yes -- open interest shifts as new contracts are written or existing ones closed throughout the session, so support and resistance strikes derived from OI can shift session to session, unlike a purely chart-based support/resistance level.
