I have been trading just over a year now starting with a older imac moving up to a Mac bookpro and the trading software I have been using is from Trendsetter starting with Personal Hotline and six months ago moving up to there HotlineX software, upgrade was to use real-time data for intraday trading. Using the Mac for trading has defiantly presented challenges as the mass trading software vendors is focused on the windows operating systems. I am new to the site and was surfing the forums and wanted to add a comment on trading with the Mac platform.
