I'll repost this from the other thread on the NQ - you didn't mention in this thread that your trading was on a simulator, and I think the question is of interest in this thread:
---------------------------------------------------------------------------
One question for you - how does your simulator come up with the fill prices? Last tick, bid/ask or how?
I ask because it sounds like your style is to jump on momentum thrusts - and this can produce slippage. If you are doing 200 trades (as you stated in the other thread) - and let's assume you would only get slippage on entry since you would be bailing out when the momentum dries up - 1 tick slippage per trade would amount to a difference of $1000/day. Even if you only had slippage on 10-20% of your entries (which IMO would be optimistic), that would still be $100-200 a day.
As someone I know from another board like to say - you have to pay the vig.
