I have had the values 0.5 in the margin and maint margin boxes and 500 in the margin / unit box but this does not appear to stop me from placing orders when I have too many contracts working. Also on the accounts tab I see that there are 0 or null numbers againts sim101 margin boxes. Do I need to set this up elswhere other than in options/simulator?
Thanks
PS I'm running NT6.5
