You can always ask Jerry to add Prorealtime, or any other data provider that not currently supported by QT, if the provider is willing to cooperate with QT.
it's quite good in it self, depends a bit on what you want, you could always get yourself a trial of 7 days. For me the only thing that might work better with QT is the drawing of trendlines. At this moment however it's not compatible with QT as far as I know.
