do you want to say that..........if open intrest of put decreases then stock is bullish........and if open intrest of call decreases....stock is bearish...........................am i missing something.....please be precise.
1.call writers write the call options and sell them in the open market with the intention that a stock price cannot move beyond a level and sell them at a particular price -- so if they see that the price of stock moving beyond a point they just want to cover up the open positions and close the contract and thus the oi decreases
so call writers are considered as generally having a bearish view
2.put writers write the put options with the intention that the stock price wont fall further down and then sell a particular contract at a strike price in open market so if the value of the stock is falling down they tend to cover up their open positions otherwise they will be in loss
so put writers considered to be having a bullish view
hope this solves u r doubts
