What is Put/Call Ratio?  
Put/Call ratio (PCR) is a popular derivative indicator, specifically designed to help traders gauge the overall mood of the market. The ratio is calculated either on the basis of options trading volumes or on the basis of the open interest for a particular period.  If the ratio is more than 1, it means that more puts have been traded during the day and if it is less than 1 it means more calls have been traded. The PCR can be calculated for the option segment as a whole which includes individual stocks as well as indices.

How is the Put/Call ratio calculated?
a) Open Interest Put/Call ratio
Open Interest PCR is calculated by dividing the total number of open interest in all the available Put option strikes across the series by the total number of open interest in all the available Call option strikes across the series.

PCR (OI) = Put open interest /Call open interest

b) Volume Put/Call ratio

Volume PCR is calculated by dividing the total volume traded in all available Put option strikes across the series by the total volume traded in all available Call option strikes across the series. 

PCR (V) = Put traded volume/Call traded volume.
