nah, unless you're trading 9 contracts, at which point $40 is negligible, you can make money on ER2.
But quite honestly, It's easy to make money on ER2 daytrading or scalping it but it's very easy to lose money on it, too. I was just looking at my P&L on ER2 and although 80% of my daytrades on Er2 are profitable, the big swings of losses kept my profits at a minimum. That can be attributed to my strategy, too. It's hard to keep tight stops on ER2 when scalping.
Swing trading ER2 is much profitable for me.
I prefer to daytrade the YM or NQ. Behaviour is less erratic.
