I know this post is going to sound like i work for Lightspeed and i am pumping their platform but this is all true as far as im concerned. Lightspeed is by far the most dynamic daytrading platform on the street. I have tried quite a few platforms but none are as fast , clear, user friendly and reliable for active traders. The Lightspeed team starting from the top is extremely helpful and friendly with all my questions and needs. They are always willing to listen and are open for for new ideas from active traders to upgrade their platform. Most importantly, my trading profits are by far greater here at Lightspeed than on any other platform i've traded at. Good Luck and before you try another platform give Lightspeed a test drive. You won't be disappointed
Have you checked your available RAM and/or CPU usage when running all those charts? ...could be at the limit which could be causing the quotes to freeze up
