Writing Put or Call is big players game and it carries "Unlimited Loss" and "Limited Profit". Thus the more number side is writers side done by big players by thinking that that side will never come!
Not perfect standard, but, Generally my analysis of PCR: PCR above 1.4 means 14 put with 10 call, means more put written and that put side is down side which will never come. PCR below 0.9 means 9 put with 10 call, means more call written and that call side is up side which will never come.
As mentioned in previous posts, PCR above 2.8-3.2 is overbought and PCR below 0.4-0.6 is oversold. According to Trend Strength and its Force to change the trend may alter this figure sometimes.
I don't care NSE PCR data or any brokers PCR data. Here is NSE link for
