I haven't been too happy with them. The software used to be very stable, but sometime in the last couple of weeks they were down most of the day. Also, I'm having a problem where if I open the software, it works fine, but after a while, sometimes just a few minutes, it quits working. I go to change a symbol, and all I get is an hourglass, no ability to change the symbol. And it's now taking several minutes to shut down, and a couple additional minutes to start back up.
I had some spyware problems, but I installed the software on my second computer, and the same issues. I haven't been using TT for trading much, so I haven't made a point of calling them yet, but I will soon.
Also, I like to use smart order routing, and the software always routes the order to TRAC. Even if there's liquidity through a MM or another ECN. So the order just sits there, because nobody trades with TRAC, except Tracktrade, and there's not very much liquidity anyway.
