I am currently trading through a Redi broker and primarily trade QQQ for scalp/intraday swing moves. I am trading relatively small share size as i develop my consistency. I am very disciplined about stops and my system gives adequate opportunities to make profitable trades - why i don't take more signals is a subject for another thread . So my only real risk of ruin are commission costs. I have never seriously considered IB because of all the bad comments on support. However, the past few days i have read through many of the comments here and played with the TWS demo and I'm very seriously considering opening an account with IB. I have a couple of questions. 1) My main concern is what happens when I'm in a trade and i have problem like a lost cable connection and need to talk to someone. This very rarely happens but I'm curious what I can expect in terms of telephone response time. 2) Since i trade primarily the QQQ's through ISLD or REDI I would be interested in hearing from other QQQ traders about their experience with IB trading the QQQ's. Really curious about how people use the system to trade - mouse clicking vs. hot keys. Thanks for your comments. I have really gained some valuable information and insight from this site over the past month i have been using it.
