Put Call Ratio (PCR): Meaning, Calculation & How Traders Use It

The Put Call Ratio (PCR) is one of the most widely used indicators in options trading. It helps traders understand market sentiment by comparing the trading volume of put options to call options. In 2025, with increasing activity in derivatives markets, PCR remains a go-to tool for gauging whether investors are leaning bullish or bearish.

What Is Put Call Ratio (PCR)?

The Put Call Ratio measures the ratio of put option contracts traded versus call option contracts.

1. Put Options: Bets that the market will go down.
2. Call Options: Bets that the market will go up.

Formula:

Put Call Ratio (PCR)=Put Option VolumeCall Option Volume\text{Put Call Ratio (PCR)} = \frac{\text{Put Option Volume}}{\text{Call Option Volume}}Put Call Ratio (PCR)=Call Option VolumePut Option Volume​

Example: If 80,000 put contracts and 100,000 call contracts are traded, PCR = 0.8.

How to Interpret Put Call Ratio

• PCR < 1 (Low Ratio): More calls than puts → bullish sentiment.
• PCR > 1 (High Ratio): More puts than calls → bearish sentiment.
• PCR around 1: Neutral market sentiment.

👉 Traders often use PCR as a contrarian indicator:

• Extremely high PCR → Market may be oversold (potential bounce).
• Extremely low PCR → Market may be overbought (possible correction).

Why Is Put Call Ratio Important for Traders?

1. Measures Market Sentiment: Quickly shows whether traders are buying protection (puts) or betting on gains (calls).
2. Identifies Extremes: Helps detect overbought/oversold market conditions.
3. Supports Strategy Building: Traders combine PCR with technical indicators to refine entry/exit points.
4. Useful for Nifty & Bank Nifty: Widely tracked in Indian markets for short-term trends.

Limitations of Put Call Ratio

• Not Always Reliable: Sudden news events can shift market sentiment instantly.
• Market Specific: PCR levels vary across indices and sectors.
• Better with Other Indicators: Works best when combined with tools like RSI, open interest data, or volume analysis.

Practical Use of PCR in Trading

• Track Nifty PCR or Bank Nifty PCR daily for short-term insights.
• Use it with support & resistance analysis.
• Watch for extreme PCR levels as potential reversal signals.
• Avoid relying on PCR alone—always confirm with other technical tools.

The Put Call Ratio is a simple yet powerful way to measure market mood. It tells you whether traders are leaning bullish or bearish and can highlight potential turning points. However, it’s most effective when used with other indicators rather than as a standalone tool. For options traders in 2025, PCR remains a vital sentiment gauge in both global and Indian markets.
