If you recall back in the days of QT, it was required to have two user names. One for QT, and one for MBT Navigator, now known as MBT Desktop Pro. Something about their API.
When using MT, this problem was resolved and only one user name was required to operate both software programs simultaneously. Until a few days ago. I believe it was last
summer that MB Trading was purchased by TradeKing. Then TradeKing was purchased by Ally. Last weekend the transition was made for MBTrading, which is now known as
MBTrading by Ally. "But" I now have to go back to using two user names when running both programs simultaneously, or if not, the program I open "last", does not work. This just
seems to have happened out of the blue, which is not a problem for me as I still have two user names. But strange that this quirk popped up. Just a heads up for you folks at MT.
