What Is PCR in Options Trading?
PCR stands for put-call ratio. It compares put activity with call activity in the options market. Traders often use it to understand whether the options chain is leaning toward put-side support, call-side pressure, or a more balanced structure.
Key Takeaways
- PCR is a sentiment and positioning indicator, not a guaranteed signal.
- A high PCR can suggest more put activity, while a low PCR can suggest more call activity.
- PCR should be read with open interest, price action, volatility, and support/resistance.
- PCR can change quickly near expiry.
- PCR is most useful when it confirms other market evidence.
How PCR Is Calculated
The simple idea is:
PCR = Put activity / Call activityThe activity can be based on open interest, volume, or change in open interest depending on the data source. This is why traders should know which PCR they are looking at before interpreting the number.
How To Read PCR
| PCR Condition | Common Interpretation | Caution |
|---|---|---|
| Around 1.00 | Balanced put and call activity | Direction still needs confirmation |
| Above 1.00 | Put activity is higher than call activity | Can show support, but can also become crowded |
| Below 1.00 | Call activity is higher than put activity | Can show pressure, but can also reverse quickly |
For Nifty and Bank Nifty, PCR is often more meaningful when combined with the nearest support and resistance zones.
Why PCR Alone Is Not Enough
PCR does not tell the full story. A high PCR near support may show put writing, but if price breaks support with rising call additions, the interpretation can change. A low PCR near resistance may show pressure, but if price sustains above resistance, the structure can shift.
Use PCR as one input, not as a trading instruction.
Practical Use In Daily Reports
In a daily market report, PCR can help answer:
- Is the options chain balanced or one-sided?
- Is support backed by put activity?
- Is resistance backed by call activity?
- Is the PCR confirming the index move or contradicting it?
- Is the reading high confidence or expiry-sensitive?
Common Mistakes
- Treating PCR as a buy/sell signal.
- Ignoring price action.
- Ignoring expiry context.
- Comparing PCR from different sources without knowing the calculation method.
- Using PCR without checking open interest concentration.
