I too am trying to learn T&S, and to that end am evaluating market profile-type software that lets you see Bid/Ask volume at each price level on a bar chart. My question relates to what I'm seeing in the cumulative volume delta and Bid/Ask/Sales for each candle. On a regular T&S window many times I've seen tons of small prints and block sales at the bid and price goes nowhere yet a few small sales on the ask and price moves up. Also the reverse. I'm seeing this on the demo software too- YM trades down all morning on decent volume but at some point around 10:30 AM there is a 60 point rally but I'm seeing only negative volume delta for every single 3m bar and the bid is getting hit at 5 times the ask.How is price going up if the "tape" shows only selling by any objective measure?What else moves price besides hitting the bid or ask?
