Comment on Open Interest, MaxPain & Put Call Ratio(PCR)
You don’t look at the % change, but also the OI itself. Your logic of 8150 has a huge change in OI and also OI itself is highest, yes indicates that 8150 is a good support for the series. But you will need to track these closely, as they can keep changing rapidly.
At 8200, don’t just look at % change, but also on the total OI itself.
