RE:RE:Flash 338 ;I use StockCharts.com. If you go to that site, volume by price can be found under overlays (I set opacity to 0.1). Although not perfect, it can show what price it acting as a hurdle to get through and once though the smaller peaks show what price may prove to be resistance. I'm now using it as a secondary indicator like regular volume. It's nice when it lines up with things on your standard charting.
