What up Kev!
The top T&S only shows orders greater than, or equal to 2000. The bottom T&S shows all orders strictly less than 2000. Here are the settings...
The top gets ride of a lot of the white noise, for example I took a trade on $NKLA yesterday when I felt the bulls were gonna rally, and here is what the tape looked like after it broke $29.00 (from the bottom)
The top T&S tells me if the bigger players are interested in the move, and the bottom one gives confirmation by the rate at with which orders are being processed. So if price is pressed up against some key level, lets say $29, and some large orders starting going through the ask at 29$ , and my bottom T&S lights up green, it's pretty fair to assume we're gonna break that level with a lot of momentum.
