They are, and have been, experiencing bad latency. I've gotten fills that came as a surprise. And they have the worst of all worlds with their problem. They're not sure how to fix it. Anyone know of a rock-solid front end software set-up, with low latency? If not, I think I'll give Real Tick a look.
Instaquote had bad latency again this morning. You are forewarned. If you trade with Instaquote you will be paying people to lose your own money.
