I too have tried many of these alogrithmic systems in the past. It's plain and simple, some work and some don't. The concept is flawless, the delivery can be a totally different story. I never bought from Trade Tech but I have purchased from many companies like Trade Tech. After reading this entire chat thread, I feel for the people that aren't being treated right. After reading the last post, I think that this person has a great point. All that the broker is, is a conduit to the "code" that the system developer has produced. The broker just executes the trades and has a zero say about anything else. I have found dozens of blogs like this about companies that offer trading systems with guarantees. BUY THEM AT YOUR OWN RISK! Save your money and just go to Las Vegas!! DONT BLAME THE BROKER!
