Is there a trading platform that anyone would recommend that can handle the SPY's? The firm I work for has a platform that has issues with stuck ecn's when the market starts to move quickly making it nearly impossible to scalp the SPY's and QQQQ's. I talked to our head technician and he said that most trading firms have the same issues we have. Said it has something to do with too much data having to be checked and processed and fed through the lines. I dont know much about all this but was hoping someone else did. Thanks.
