What is Put Call Ratio?
The Put Call Ratio (PCR) is a widely used indicator in F&O trading that measures overall market sentiment. It's calculated by dividing the total Open Interest (OI) or trading Volume of Put options by that of Call options for an underlying asset like Nifty or BankNifty.
At its core, PCR tells you whether traders are buying more puts (bearish bets) or calls (bullish bets). A higher PCR indicates more puts relative to calls, suggesting bearish sentiment, while a lower PCR points to more calls, implying bullishness.
PCR Formula:
PCR = Total Put Options OI (or Volume) / Total Call Options OI (or Volume)
Example: If Nifty has 1,20,000 contracts of Put OI and 1,00,000 contracts of Call OI, the PCR would be 1,20,000 / 1,00,000 = 1.20. This means there are 1.2 put contracts for every 1 call contract, indicating a bearish bias.
PCR acts as a quick pulse check on market sentiment. High PCR = more puts (bearish sentiment), Low PCR = more calls (bullish sentiment). Don't trade it in isolation.
Q: What does PCR mean in stock market?
A: PCR means Put Call Ratio, an indicator that reflects market sentiment by comparing the volume or Open Interest of Put options to Call options.
PCR Volume vs. PCR OI
When discussing PCR, it's crucial to distinguish between two types: Volume-based PCR and Open Interest (OI)-based PCR. Both reflect sentiment but offer different perspectives.
| Attribute | PCR (Open Interest) | PCR (Volume) |
|---|---|---|
| Calculation Basis | ✓ Total outstanding Put OI vs. Call OIReflects positions held over time | ✗ Total Put Volume vs. Call Volume traded todayReflects intraday activity |
| Sentiment Indication | ✓ Longer-term market positioning and conviction | ✗ Short-term, intraday sentiment and immediate momentum |
| When to Use | ✓ Swing trading, positional trades, identifying major support/resistance | ✗ Intraday trading, quick shifts in sentiment, reacting to news events |
| Interpretation | ✓ Slower to change, indicates underlying trend bias | ✗ More volatile, can signal quick reversals or exhaustion |
Pro Tip: Smart traders monitor both. Volume PCR shows where the immediate action is, while OI PCR shows where conviction is building up over days.
Volume PCR is dynamic and can fluctuate wildly intraday. Use it to confirm immediate strength or weakness. OI PCR is more stable and provides a clearer picture of broader market sentiment.
Q: What is OI ratio in options?
A: OI ratio is synonymous with PCR OI, the ratio of total Put Open Interest to total Call Open Interest.
Decoding PCR Values
Interpreting PCR isn't about a single magic number, but understanding the ranges and context. Here's a general guide:
| PCR Range | Interpretation | Action Bias |
|---|---|---|
| Below 0.5 | ✓ Extreme bullishness / Overbought zoneToo many calls, potential for reversal. | ✗ Be cautious with fresh longs; consider contrarian shorts. |
| 0.5 - 0.8 | ✓ Bullish sentimentMore calls than puts, but not yet extreme. | ✓ Look for long opportunities or hold existing longs. |
| 0.8 - 1.2 | ✓ Neutral / Sideways market expectedBalanced number of puts and calls. | ✓ Range-bound strategies like Iron Condors or short Strangles. |
| 1.2 - 1.5 | ✓ Bearish sentimentMore puts than calls, but not yet extreme. | ✓ Look for short opportunities or hold existing shorts. |
| Above 1.5 | ✓ Extreme bearishness / Oversold zoneToo many puts, potential for reversal (contrarian signal). | ✓ Be cautious with fresh shorts; consider contrarian longs. |
Remember, these are general guidelines. Always cross-reference with price action, chart patterns, and other indicators.
Q: What does PCR of 1 mean?
A: A PCR of 1 means an equal number of Put and Call options (OI or Volume), indicating a neutral market sentiment.
High PCR: The Contrarian Play
A high PCR (typically above 1.2, and especially above 1.5) indicates that a significant number of traders are buying Put options. This suggests strong bearish sentiment or fear in the market. However, seasoned traders often view extreme PCR values as contrarian signals.
When everyone is bearish (high PCR), the market might be oversold. Often, extreme fear precedes a bounce or reversal. Smart money might be taking the other side.
Real Nifty Example (Historical Observation):
Consider the Nifty movement in early 2026:
- February 1, 2026: Nifty around 25,400 with PCR OI at 0.72 (bullish to neutral).
- March 13, 2026: Nifty drops to 22,800. PCR OI spikes to an extreme 1.84. This signaled extreme fear and an oversold market.
- March 17, 2026: Nifty bounces significantly to 23,158 – a gain of 358 points in just 4 trading sessions from the low.
This historical pattern highlights how an extremely high PCR can act as a signal for a potential market bottom and a subsequent bounce.
Beginner traders often interpret high PCR as a direct signal to short. Don't blindly short when PCR is extremely high; it could be a capitulation point.
How to Trade the High PCR Contrarian Signal:
If Nifty shows an extreme high PCR, a contrarian strategy would be to look for long opportunities. Let's consider a hypothetical trade based on the March 13, 2026 scenario:
You initiate a long position by buying Nifty March 22,900 CE around ₹120 on March 13, anticipating a bounce from the extreme PCR of 1.84.
Verdict: The market follows the contrarian signal, resulting in a solid profit.
Nifty attempts a bounce, hitting 22,950, but then loses momentum. Theta decay starts to eat into your option value.
Verdict: A minor loss due to insufficient momentum and theta decay.
Despite the high PCR, Nifty fails to bounce and instead drifts lower or remains below your strike price. Your 22,900 CE premium erodes rapidly.
Verdict: Max loss for option buyers (premium paid) if the contrarian signal fails.
This example demonstrates the potential rewards and risks of acting on extreme PCR values. Always manage your risk with stop losses.
Q: What does high PCR mean?
A: High PCR (e.g., above 1.2, especially 1.5+) means more puts than calls, indicating bearish sentiment or extreme fear. Often viewed as a contrarian bullish signal.
Q: Is PCR of 1.38 bullish or bearish?
A: A PCR of 1.38 is generally considered bearish, as it means significantly more puts than calls. However, if it's an extreme high for recent history, it could be a contrarian bullish signal.
Q: Is PCR of 1.5 bullish or bearish?
A: A PCR of 1.5 is extremely high, indicating strong bearish sentiment. This level is often interpreted as a contrarian bullish signal, suggesting the market might be oversold and due for a bounce.
Q: Is high PCR bullish or bearish?
A: Directly, high PCR is bearish. Contrarian traders interpret extremely high PCR as a bullish signal, anticipating a market bounce from oversold levels.
Low PCR: The Caution Signal
Conversely, a low PCR (typically below 0.8, and especially below 0.5) indicates that a large number of traders are buying Call options. This suggests excessive bullish sentiment or greed in the market.
Just as extreme fear can signal a bottom, extreme greed (very low PCR) can signal an overbought market ripe for a correction or reversal. Avoid initiating fresh long positions or consider booking profits.
When PCR dips significantly below 0.8, it often means the market has rallied sharply, and many traders are piling into calls, anticipating further upside. This can be a sign of exhaustion in the bullish trend.
A falling PCR with rising price could mean short covering in calls, but an extremely low PCR usually implies over-optimism. It's a signal to protect your gains or look for shorting opportunities on a contrarian basis.

Integrating PCR into Your Trading
PCR is a powerful tool, but it should never be used in isolation. Here’s a 5-step process to integrate it effectively:
- Identify PCR Trend: Look at PCR over several days. Is it rising (bearish sentiment building) or falling (bullish sentiment building)?
- Spot Extremes: Note when PCR crosses critical thresholds like 0.8 (bullish caution) or 1.5 (bearish contrarian).
- Cross-Verify with Price Action: Does the price action confirm the PCR signal? For example, if PCR is extremely high (bearish), but price is forming a bullish candlestick pattern, it strengthens the contrarian long signal.
- Check Other Indicators: Confirm with tools like OI analysis at specific strikes, FII/DII data (available on OptionX's dashboard), or technical indicators (RSI, moving averages).
- Formulate Strategy & Manage Risk: Based on the confluence of signals, plan your entry, target, and crucial stop-loss. Use OptionX’s Bracket Orders to automate your exits and prevent emotional trading.

Explore OptionX's Option ChainLimitations of PCR
While powerful, PCR isn't a silver bullet. Be aware of its limitations:
- Institutional Hedging: Large institutions often buy puts to hedge their long equity portfolios. This can inflate Put OI/Volume, leading to a high PCR even if they aren't truly bearish on the market direction. This is especially true for index options.
- No Timing: PCR tells you sentiment, but not *when* a reversal will occur. An extreme PCR can persist for several days before a reversal materializes.
- Near Expiry Distortion: As expiry approaches, deep OTM options lose value rapidly. PCR can become distorted as traders unwind positions or roll over, affecting the OI and volume dynamically.
- Ignores Strike Price: PCR lumps all puts and calls together. It doesn't differentiate between ITM, ATM, or OTM options, which carry different implications. A high PCR driven by OTM puts is different from one driven by ATM puts.
Always combine PCR with OI analysis at specific strikes (e.g., Max Pain, highest OI strikes for calls and puts) to get a more granular view of potential support and resistance levels. OptionX's Option Chain makes this easy.
⚡ Bottom Line
- PCR is a powerful sentiment tool: Use both OI and Volume PCR to gauge market mood for different timeframes.
- Extreme PCR is often contrarian: High PCR (above 1.5) signals potential bottoms, while low PCR (below 0.5) hints at potential tops.
- Never trade PCR in isolation: Always combine it with price action, OI at specific strikes, and other indicators for higher conviction trades.
