Is there any such thing as a volume based chart on TOS? I use it on Tradestation, but most of my tool are on TOS and would love to have it if there's a way to create it. I'm also curious about Volume Dots. Found this on TOS, but can't seem to access it.....may not exist anymore: https://tlc.thinkorswim.com/center/howToTos/thinkManual/Bookmap/Heatmap/Volume-dots . Anyone ever see that?
