Basic Understanding of Put-Call Ratio : The put-call ratio is calculated by dividing the number of traded put option contracts by the number of traded call option contracts.
You can calculate this ratio by below formula : PCR = Put of all strike price of all months (near, next, far) / Call of all strike price of all months (near, next, far)
Example : PCR ratio calculated for 21-Feb-20 of all strikes and all 3 months expiry.
All PUT Counts ( Near, Next, Far ):
Near (27-feb-20) 26,763,900 + Next (26-March-20) 11,383,650 + Far (30-Apr-20) 717,900
Total Count = 38,865,450
All CALL Counts ( Near, Next, Far ):
Near (27-feb-20) 26,283,975 + Next (26-March-20) 6,876,450 + Far (30-Apr-20) 415,200
Total CALL counts = 33,575,625
PCR = Total Puts / Total Calls= 38,865,450 / 33,575,625 ⇒ 1.16
Conclusion: Here PCR is greater than 1 ( > 1 ) means traders seeing a bullish scenario in the market and most of the traders write/sell Put contract rather than Call, the most probably nifty index will go up, when it reaches max limit then possibility will be turned on the market on the opposite direction on that high limit of PCR depending on market and traders sentiment, you need to monitor this value on a daily basis to know market movement and can take your position accordingly.
