Ah sorry no, I did try level 2 about 10 years ago but I gave it up, couldn't really make it work for me, kept reading it wrong and making bad trades... Maybe I just didn't give it enough time though.

I know it was useful to a lot of people then because you could tell when the large orders were about to exhaust, order for 10k, 10k, 10k, 2.7k and done. But now everyone puts on icebergs with random amounts so it's impossible to tell anymore.

I think it's a lot more useful if you're scalping, couldn't really see the point of using it on the time scales I usually trade over. Maybe good for better entries and exits, dunno. Almost all my trades are set by limit orders way in advance anyway.
