The underlying Put-Call Ratio (PCR) derived from NIFTY OI distribution is one of the most-followed sentiment metrics in Indian F&O. PCR above 1.3 usually signals heavy put writing (bullish), below 0.7 signals heavy call writing (bearish), and readings between 0.9 and 1.1 are neutral zones where the market waits for a directional catalyst. We calculate NIFTY PCR live from the NSE option chain and update it across the full trading session, including each expiry separately so weekly and monthly positioning are never conflated.
Reading the NIFTY call-vs-put OI battle intraday
Watch the NIFTY call-put OI gap during the first hour of trade. Institutional option writers commit their positioning early, and the direction of that first-hour commitment often sets the day's bias. If the gap widens in puts' favour while spot holds, that's confirmation of bullish intent. If calls keep adding into a rally, the rally is usually being sold into. The live mode streams updates throughout the NSE F&O session so you can react as positioning changes.

How the NIFTY ratio changes intraday

Nifty 50 (NIFTY) Call vs Put OI: Strike Distribution
What does NIFTY OI distribution reveal?
Beyond the total call vs put OI, the distribution across strikes matters. Is OI concentrated at a few strikes or spread across many? Concentrated OI indicates strong conviction at specific levels — those strikes matter. Spread OI indicates uncertainty or broad hedging — the specific levels matter less individually.
Concentrated NIFTY OI patterns
When put OI is concentrated at one or two strikes just below current price, support is narrowly defined. Expect strong reactions at those specific levels. When call OI is concentrated at specific strikes above, resistance is sharp. These narrow concentrations often act as magnets or walls for price action on Nifty 50.
Spread NIFTY OI patterns
When OI is spread across many strikes, no single level dominates. Price can move more freely without encountering strong resistance or support. These environments are more suitable for trend trading than level-based trading because the chart does not offer sharp entry or exit points.
Reading distribution as of 21 May 2026
Look at the Call vs Put OI chart not just for totals but for how the OI is distributed across strikes. Concentrated distributions call for level-based strategies. Spread distributions call for trend or range strategies. Adapting to the distribution improves your strategy fit on NIFTY.
