What it really means
It is like checking whether the market is paying more attention to protection or upside participation.
Positioning
Put-Call Ratio
Put-call ratio compares put activity or open interest against call activity or open interest.
In one line PCR compares put interest with call interest.
Ratio
Puts divided by calls.
PCR is best treated as context, not as a standalone trading system.
Quick example
A PCR of 0.70 means call interest is larger than put interest. That can imply a less defensive positioning mix.
Why traders care
- PCR is a quick sentiment and positioning context signal.
- Very high or very low readings can hint at crowded market behavior.
- It becomes more useful when combined with OI distribution and price.
What beginners get wrong
- Treating PCR as a direct buy or sell signal.
- Ignoring whether PCR is based on volume or open interest.
- Using raw PCR without market context.
