There are two types of PCR – 1. PCR OI 2. PCR Volumes.
PCR OI = Total Put OI / Total Call OI
Few traders prefers to calculate PCR for particular expiry, while few calculate it using combined data.

Many software/apps/websites provides PCR OI (all expiry) and some gives us an option to select particular expiry as well.

The data, which is already expired, shall not be taken into consideration for PCR. That’s my view and it may differ with others.

I got the same reply from @AshishZBiz, @Niteshca7
and @vishal_o82
It would be great if others can share their calculation as well.
