What is PCR in Options Trading? Put-Call Ratio Explained
The Put-Call Ratio is one of the most reliable sentiment indicators available to Indian options traders — and it's completely free. Once you understand how to read PCR, you'll have a powerful edge in deciding whether the market is likely to go up or down. Here's everything you need to know.
The PCR Formula
PCR is simple to calculate:
For example, if Nifty's total Put OI is 1,20,00,000 and total Call OI is 1,00,00,000, the PCR is 1.20. This means there are 20% more open put contracts than call contracts — a moderately bullish signal.
PCR can be calculated for a single expiry (weekly or monthly) or across all expiries combined. The Suhrid dashboard uses the combined PCR for a broader market view.
How to Read PCR — The Interpretation Table
PCR is a contrarian indicator. When too many traders are positioned one way, the market tends to move against them. Here's how to interpret different PCR levels:
| PCR Level | Signal | What It Means | Suggested Bias |
|---|---|---|---|
| Above 1.3 | Strongly Bullish | Extreme put buying — excessive bearishness. Market often bounces from here. | Look for call buying opportunities |
| 1.1 – 1.3 | Bullish | More puts than calls — mild bearish sentiment. Contrarian bullish signal. | Lean bullish, confirm with VIX |
| 0.8 – 1.1 | Neutral | Balanced positioning. No strong directional signal from PCR alone. | Wait for other signals to confirm |
| 0.6 – 0.8 | Bearish | More calls than puts — excessive optimism. Market often corrects from here. | Lean bearish, confirm with VIX |
| Below 0.6 | Strongly Bearish | Extreme call buying — euphoria. High risk of a sharp reversal downward. | Look for put buying opportunities |
Why PCR is a Contrarian Indicator
This is the part that confuses most beginners. Intuitively, you might think: "If everyone is buying puts, the market must be going down." But that's backwards.
When PCR is very high, it means a large number of traders have already placed bearish bets. Most of that selling pressure is already in the market. There are fewer sellers left to push the market lower — and a lot of trapped bears who will need to cover (buy back) their positions if the market doesn't fall. This creates upward pressure.
The same logic applies in reverse for low PCR. When everyone is bullish and has bought calls, the buying is already done. The market has less fuel to go higher and more risk of a correction.
Using PCR with VIX for Confirmation
PCR alone can give false signals. The most reliable setups combine PCR with India VIX:
PCR + VIX Combinations
Strong Bullish: PCR above 1.2 + VIX below 16 + VIX falling → High-confidence bullish setup. Buy calls or sell puts.
Strong Bearish: PCR below 0.8 + VIX above 18 + VIX rising → High-confidence bearish setup. Buy puts or sell calls.
Conflicting signals: PCR bullish but VIX rising → Caution. Reduce size or wait.
Neutral zone: PCR between 0.8–1.1 + VIX between 14–18 → No strong edge. Avoid forced trades.
The Suhrid live dashboard combines PCR, VIX, and OI data automatically to generate a directional signal. See the full framework in our Call or Put decision guide.
PCR for Intraday Trading
For intraday traders, PCR is most useful when tracked throughout the session, not just at open. Here's a practical approach:
At 9:20 AM: Note the opening PCR. This sets the baseline sentiment for the day.
At 11:00 AM: Check if PCR has risen or fallen from open. A rising PCR (more puts being added) during the session is bullish. A falling PCR (more calls being added) is bearish.
At 1:30 PM: PCR changes near the end of the session can signal institutional positioning for the next day.
Where to Find PCR Data
The most reliable source is the NSE Option Chain page. Scroll to the bottom of the option chain table — NSE shows the total Put OI and Call OI, and you can calculate PCR yourself. The Suhrid dashboard calculates and displays PCR automatically, updated every 60 seconds.
Common Mistakes with PCR
1. Using PCR for individual stocks. PCR works best for index options (Nifty, BankNifty) where there's high liquidity. For individual stocks, OI data can be thin and misleading.
2. Ignoring the trend of PCR. A PCR of 1.2 that has been falling from 1.5 is less bullish than a PCR of 1.2 that has been rising from 0.9. The direction matters as much as the level.
3. Treating PCR as a timing tool. PCR tells you about positioning, not timing. The market can stay overbought or oversold for longer than you expect. Use PCR for bias, not for precise entry timing.
Frequently Asked Questions
What is PCR in options?
PCR (Put-Call Ratio) is the ratio of total Put Open Interest to total Call Open Interest. It is calculated as: PCR = Total Put OI / Total Call OI. A PCR above 1 means more puts are open than calls, which is generally a bullish contrarian signal.
Is high PCR bullish or bearish?
A high PCR (above 1.2) is generally considered bullish. It means a large number of traders have bought puts (bearish bets), which often signals excessive pessimism. Contrarian logic says when everyone is bearish, the market tends to bounce. Conversely, a low PCR (below 0.8) means excessive call buying, which can signal a market top.
What is a good PCR for Nifty?
For Nifty, a PCR between 0.9 and 1.3 is considered the normal range. PCR above 1.2 is bullish, PCR below 0.8 is bearish, and PCR between 0.8 and 1.2 is neutral. These are guidelines, not absolute rules — always confirm with VIX and price action.
How to use PCR for intraday trading?
For intraday trading, check PCR at market open and again at 11 AM after the initial volatility settles. A rising PCR during the session (more puts being added) is bullish. A falling PCR (more calls being added) is bearish. Combine with VIX and OI data for best results.
