Hi, guys, I plan to buy a desk top only for auto trading.
My intended trading 4-6 futures in multi chart windows(1 future in 1 open window with AFL indicator on); Trading signals tend to be at the end of bars, say around 58 or 59 second at the 1 min bars. If the chart refreshes or rendering delay, the trade signals could disappear at the beginning of the next bars. I compare the calculation time of same AFL script on 2 different PCs: 0.005 seconds on an old Windows XP desk top (only 1G RRM); 0.05 seconds on a dual cord windows vista lap top. It seems windows vista consumes more memories than it adds. Windows XP can run AFL quicker. However there is GDI lock to allow only 1 chart refresh at one time in all previous versions Windows except Windows 7. The Windows 7 allows multi charts to refresh at the same time. So my choice should be a PC with Windows 7 operating system. Am I correct? I would like to have the inputs from you. Brgds/Bill Zheng
