Is there a reason why e-trade pro runs slow on iMac ? everything is find until market opens and internet speed is not the issue i have about 700 mbps download speed and 35 for upload.
Have you tried to ask developers about that case and issue ? I am more than sure they will be happy to reply to you. Also please describe what is actually slow for you really ? I do not see anything wrong with it on PC, but maybe I am missing something here.
basically the minute the market opens is like everything slows down kind of freezing can't really adjust charts smoothly and sometimes even locks up completely.
