Reel-time scanner tutorial for thinkorswim

right here an interesting article on how to set up a scanner in TOS, to select stocks with a large range in real time – and if the stacks from the search run out, you can look for something for a reversal.
interesting.
does anyone have a help on the TOS language? for example, how to upgrade the scanner for monitoring of those squeezed into flat for five minutes? or something like that..
