I only watch the market depth from the TS matrix along with T&S table next to it. While watching the depth, you can see traders putting orders on then taking them off. At times, the big orders stay at one level but don't disappear. The interesting thing when that happens, is a another big market order taking out the limit order and push the market beyond the trading range, causing a breakout. It's true you can't tell if the breakout will continue, but it does give a good indication that it's possible. This is the part you don't see in level II but on T&S. Without it I would have thought the order was removed from the market like before.

I think watching them side by side is very informative because just level II might not give a full picture. But the biggest problem is during the opening hour. Moves too fast to see all the orders going by.
