Hi Salty. Sorry for taking an eternity to reply o your Question.
No, I wouldn't go as far to say that i am a learned level ll user. I know a little, but mainly i really like the DAElite platform. My trades come from reading the charts (which i've been practicing since i was 16). The L2 screen i feel gives me a more 'microscopic view' of what is happening at a particular price level, in my view. I certainly dont know as much about that aspect of trading as the likes of Mr.Charts and the one and only Naz!
