PCR Above 1 — Bullish or Bearish?

Half the internet says a high put-call ratio is bearish. Our dashboard tags 1.38 as bullish. Both can be right — because there are two different PCRs, and they measure different things.

The confusion is real and worth clearing up properly. When someone quotes "PCR above 1 is bearish," they are almost always describing volume PCR — puts traded today versus calls traded today. When a derivatives desk (or this site) quotes PCR, it is almost always open-interest PCR — put positions still standing versus call positions still standing. Same name, different metric, and on high readings they often point in opposite directions.

Why high put open interest usually reads bullish

Index put open interest is dominated by put writers — institutions selling puts to collect premium. A put writer is making a specific bet: the index stays above the strike they sold. Heavy put OI at a level therefore marks strikes that large sellers are prepared to defend — which is why traders treat big put-OI walls as support. When the standing ratio of puts to calls is high, it usually means writers are confident, not that buyers are panicking.

You don't have to take the convention on faith

This is where flow data earns its keep: instead of assuming who created the put OI, you can watch. On 31 July 2026, our NIFTY OI-PCR read 1.38 and was tagged bullish. The tape that day recorded 91 put-writing events against 70 put-buying events, and the single largest put flow of the session was ₹67 crore of NIFTY 24300 PE writing. The open interest behind that 1.38 was predominantly sold, not bought — the bullish tag wasn't a convention, it was an observation.

When the reading flips

At extremes, the logic inverts. If nearly everyone is short puts, the market is complacent — and a shock forces all those writers to buy back at once, accelerating the fall. That's why very high readings (roughly 1.6+ on NIFTY) are treated as a reversal warning rather than a stronger buy signal. Our dashboard treats PCR the way the pros do: temperature, not a signal. Between roughly 0.9 and 1.1 we call it neutral; nothing about the number alone tells you what happens next.

What we show on the dashboard

The PCR chips on the flow page are labelled (OI) and computed from open interest, with the reading conventions above. Hover the label for the one-line version of this article. If you're comparing our number against a volume-PCR figure from another site, expect them to disagree — they're answering different questions.
