I was looking for an indicator that could measure volume at specific price points, specifically the bid and ask prices to detect aggressive buyers and sellers in a given market. I’m not talking about level 3 data that shows volume at each price, but rather a more generalized indicator that shows the total number of shares traded at an offer/bid price in a given candle, whatever that offer/bid may be at the time. Does this exist currently on a platform like thinkorswim or tc2000, or is this something I’ll have to build from scratch?
