I have been a TOS customer for 3 years now and I've used many other platforms. I have some complaints but I've never experienced a platform freeze with them. I don't love their commisson structure nor their recent affiliation with groups like Investools which is a totally worthless sales organization selling education in trading I think. They've had some trully sleazy types on their afternoon chats too lately. The guys from Best Choice software was a real low point for them. Those chats used to be good but I guess the firm has grown so fast and there are so many new customers who need to know what a bid and an ask is, it was inevitable that the culture would change. So I'm not a company shill. Still, their pace of innovation is staggering. Customer service is A+ (I hear nightmares about IB on that). I'm trying to grasp their Prodigio robotic trading system with both hands. It's new and in development but awesome. It's a firm built by great traders for traders.
