Put call ratio above 1, means more puts have written, want to know if in ratio above 1, is there any point in ratio where we can say more puts have been bought?

The whole analogy of PCR revolves around the fact that the option writers are the smarter lot, and hence you follow what they are doing. So yeah if PCR is more than 1, that means more puts are written than calls, that also means that more puts have been bought than calls.

But you are assuming that option writers are smarter and hence form an inference that since more puts are written, market is probably bullish.

@Nishant, when asking questions, make sure to ask in the right category, and also use proper tags. You have chosen, algos/ and tags as options. This will not help, if there are others out there searching for the same question u have.
