The slippage is terrible and I find I can't control my risk due to the lack of volume. There are alot of "trap doors" where the prints will be 2 or even 3 points higher/lower all of a sudden, and you are stuck on the wrong side of the trade and get a crappy fill. I used to trade ER2 exclusively back in the day. I have tried on several occasions to trade the TF, only to get sliced and diced like a Billy Mays product. Just my two centavos..
