You're better off trying to figure out how the pump and dumps work. L2's don't really tell you a whole lot because they themselves can be manipulated and often are. You will see 5000 sitting at one level, watch 50k get sold, and still see that 5k sitting there. MM's hide their share counts and other tricks to manipulate the price. With the volatility the L2 can only help you out so much, but basically if you got major bid support the price is going to move up and vice versa, but of course, this isn't always accurate.
