Good day to all.. I'm presently trading ES, GBP and EUR futures running Ninjatrader 6.5 (with XP 32 bit) for a total of 9 charts running simultaneously on 4 monitor setup. My question is this, I want to run 8-10 more charts(for total of 20 charts) at same time using 6 more monitors(for total of 10 monitors). How much more RAM do I need to do this? what about XP RAM limitation? I know XP has 2-3 GB limit of usable RAM. Is there anyone on here using large number of charts with Ninja on XP system, or other windows OS? What about using a software called RAMDISK which supposedly increases XP's usable RAM to over 4GB? Please do not reply to this question unless you are or have experience using high number of charts on Ninja with XP or you are a true expert on computers/windows OS. Thanks.... P.S. And NO I wont change trading platforms. Ive aleady bought the lifetime license for Ninja..
