How to Use the Put Call Ratio Calculator
- Enter Put Volume: Input the total number of put options contracts traded. This data is available from CBOE or your broker's options chain.
- Enter Call Volume: Input the total number of call options contracts traded for the same period.

- Interpret Results: Review the PCR value and sentiment indicator. Use extreme readings as potential contrarian signals.
What is the Put/Call Ratio (PCR)?
The Put/Call Ratio (PCR) is a popular sentiment indicator that measures the relative trading activity between put options and call options. It's calculated by dividing the total put volume (or open interest) by the total call volume (or open interest).
Since put options are typically bought when traders expect prices to fall, and call options are bought when traders expect prices to rise, the PCR provides insight into overall market sentiment—whether traders are more bearish or bullish.
Interpreting PCR Values
- PCR > 1.0 (Fear): More puts are being traded than calls, indicating bearish sentiment. Traders are either hedging or betting on downside.
- PCR = 0.7 to 1.0 (Neutral): Balanced sentiment between bulls and bears. This is considered the "normal" range for equity markets.
- PCR < 0.7 (Greed): More calls are being traded than puts, indicating bullish sentiment. Traders are optimistic about upside potential.
- PCR > 1.2 (Extreme Fear): Very high put buying can signal capitulation and potential market bottoms.
- PCR < 0.5 (Extreme Greed): Very low PCR can signal complacency and potential market tops.
PCR as a Contrarian Indicator
Many traders use the Put/Call Ratio as a contrarian indicator. The logic is simple: when the crowd is extremely fearful (high PCR), it may signal a buying opportunity. When the crowd is extremely greedy (low PCR), it may signal a time to be cautious.
This approach is based on the observation that extreme sentiment readings often occur near market turning points. However, it's important to use PCR in conjunction with other technical and fundamental analysis tools rather than as a standalone signal.
Volume PCR vs Open Interest PCR
- Volume PCR: Measures daily trading activity. Better for short-term sentiment analysis and intraday trading decisions.
- Open Interest PCR: Measures total outstanding contracts. Better for longer-term sentiment analysis as it reflects accumulated positions.
- Combined PCR: Averaging both provides a more balanced view of overall market sentiment.
Types of Put/Call Ratios
- Equity PCR: Based on individual stock options. Reflects sentiment on specific stocks.
- Index PCR: Based on index options (SPX, NDX). Often used by institutions for hedging.
- Total PCR: Combines equity and index options. Provides the broadest market sentiment view.
- CBOE PCR: The most widely followed PCR, published daily by the Chicago Board Options Exchange.
FAQs
What is a good Put/Call Ratio?
There's no universally "good" PCR—it depends on context. For contrarian traders, extreme readings (below 0.5 or above 1.2) are most interesting as potential reversal signals. For trend followers, a PCR in the 0.7-1.0 range suggests neutral conditions.
How often should I check the PCR?
For swing traders, checking daily PCR is sufficient. Day traders may monitor intraday PCR changes. Long-term investors might look at weekly or monthly averages to smooth out noise and identify major sentiment shifts.
Is a high PCR bullish or bearish?
A high PCR (above 1.0) directly indicates bearish sentiment—more traders are buying puts. However, as a contrarian indicator, extreme high readings can actually be bullish signals, suggesting the market may be oversold and due for a bounce.
Where can I find real-time PCR data?
The CBOE publishes daily PCR data on their website. Many brokers also provide PCR data in their options analytics tools. Financial websites like Barchart and Yahoo Finance offer historical PCR charts and current readings.
