Guys, there different methods of calculating Put Call Ratio (#PCR).
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.

(1/n) In combined data, one take all expiry and all strikes to calculate PCR. This can be easily done in excel from Bhavcopy data.

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