I can use TradeStation without problems. I can use NinjaTrader charts, Dom, ect, without problems. I start up QT and my PC clock slows down and ruins the QT charts. The charts (and T&S) slow down more and more as time goes on. I talked to support and they say it isn't QT. But this only happens when I start up QT. Doesn't matter whether I have QT running on system time or not. I have tried old versions, ect., to no avail. Anyone ever have this problem or might know what is happening?
