When sim trading, if you plan to use 1 or 2 contracts "live" try running 8 or 10 in the sim first. Think about it: When sim trading it's far too easy to see "-12.50, -25.00" and think "no big deal" on 1 or 2 virtual contracts --- but when you start seeing "-1250.00, -2500.00" for that first tick or two moving against you, suddenly you get real focussed and hopefully can stay disciplined to your trading plan. That helped me out immensely, and made sim trading 'feel' a bit more real to me. YMMV.
