Hi nzbryant. I may be screwed, but not for the reasons you suggest:Quote from nzbryant:
Youre screwed. The comm (from the frequency) and the slippage (have you measured the slippage) on 3 and 9 minute charts will reduce your account no matter how you well you trade.
1. Commissions - You may not be familiar with IB's forex commissions so you can review them at http://www.interactivebrokers.com/en/accounts/fees/commissionForex.php?ib_entity=llc. Some simple math works the minimum RT fee to be $5.00 (this is less than 1 pip). So between the commissions and the spread (normally at 1 pip on the pairs I trade) I think the fees are quite fair.
2. Slippage - this has not been an issue. If it were, I would adjust my style and/or indicators.
