I Was using Ameritrade until last week and the worst/best thing happend to me. Their servers went down and I could not exit any of my postions. Once I sat on the phone for 10 min's waiting to talk to someone and then they said try this other server. They never once sent an email to anyone about what to do, why this happend, and a sorry. This made me look for another firn and now im opening an account with IB. I will save thousands with them its great!!
