according to my observation premium decay and change in iv on both side can give you a direction of market in intraday
when smart money enter/exit, iv and premium value change drastically..
I observe open interest also change same way…But there is no such change in volume because smart money works with high quantity.
when you get this type of signal market reverse from its short term support/resistance…
Hope this hint can help you to make your system more accurate
thank you
