PCR Trading
Strategy
The put-call ratio is one of the most misused indicators in Indian options. Here's how to read it the way it actually works on NSE — and the trap that catches most retail traders.
The put-call ratio (PCR) divides total put open interest by total call open interest. The intuition is simple — more puts than calls suggests bearish positioning — but applying the textbook US interpretation to NSE will get you chopped up. Here's the framework that actually fits the Indian market.
Why NSE PCR runs hot
On NSE indices, PCR structurally sits above 1 because of heavy institutional put writing. Big players sell puts to collect premium when they expect support to hold, which inflates put OI. So a PCR of 1.2 is not inherently bearish — it can be a sign that writers are comfortable defending lower strikes. This is why a high PCR is frequently read as contrarian-bullish, and a very low PCR (call-heavy) can flag complacency or a ceiling.
OI PCR vs volume PCR
- OI PCR uses open interest — the standing positions. It's the slower, structural read of where writers have planted their flags.
- Volume PCR uses the day's traded contracts — a faster, intraday sentiment gauge that can swing hard during the session.
For positioning and the medium-term lean, use OI PCR. For intraday momentum, watch volume PCR — but treat it as noisy.
A practical PCR framework
- Anchor to the range. Note where PCR usually sits for that specific index or stock over the last few weeks. Judge today's value against that, never against a fixed 0.7/1.0/1.3 rule.
- Read the trend, not the level. A rising PCR (puts being written / accumulated) into a stable market is supportive; a falling PCR can flag put unwinding and weakening support.
- Confirm with the OI walls. Cross-check PCR against the heaviest put strike (support) and call strike (resistance) from the max pain view. PCR tells you the balance; the walls tell you the levels.
- Use extremes contrarily, carefully. Very high PCR after a fall can precede a bounce (over-hedged); very low PCR after a rally can precede a stall (complacent). Wait for price confirmation.
The trap to avoid
The classic mistake is mechanical: "PCR > 1 = bullish, PCR < 1 = bearish." That ignores the structural put-writing bias and the instrument's own range, and it ignores trend. PCR is a context indicator, not a trigger. Combine it with price action, the OI walls and FII/DII positioning before you act.
