Jerry, I've used QT since the late 1990's and was crestfallen a few years ago when TDA said QT was being phased out as part of their boneheaded business decisions: http://www.elitetrader.com/et/index.php?threads/quotetracker-being-shut-down-for-good.239759/ (I'm eugenie98 on ET).
Since hearing about the MT project a couple years ago I've been waiting with bated breath and figure it's time to dive in.
I use IB. If you could message me the beta link that would be great.
Best,
Gene
