Quote from MajorUrsa:
Not sure what 'high leverage' is in your book, but, yep, doing it right now, evey day, YM, CAC40 and FTI. I use Buttontrader to enter and exit, and QT to view the market. QT has several very usefull features and, is the easiest to get running, compared to Sierra and Ensign. Also, I find the data-feed from IB adequately reliable, not had any serious problems with it.
Ursa..
It will depend whether the OP was serious when he said he wanted customization ... if he does then he'll need Sierra Chart or Ensign rather than qt.
