I have been searching high and low for one little indicator… a sub study that monitors the nearest 5-10 away from ATM option chains for both calls and puts. It has a center line that indicates balance (much like $tick or $trin). I want the indicator to filter volume that is ONLY filled by the Ask between the calls and puts. + values indicate more calls buying at the ask and - value means more puts are purchased by the ask. Y-axis should be either total volume or $ value. Is such a thing possible? I don’t care about market-wide averages. This is for intra-day scalping. Currently I do something like this manually with success targeting reversals, but lack any coding experience to make an indicator. Does something like that exist for TOS?
