I trade the ER2, NQ, ES, and DAX (and on occasion QM). I will trade the ER2 until spring and then see what other products I might add to replace the ER2. We actually have too many choices as traders, so there is plenty of products to trade that have decent or even better liquidity levels. I am starting to watch these products to see how liquidity goes as we move towards the new year..... http://www.cme.com/trading/prd/equity/emini-sp-mid400.html http://www.cme.com/trading/prd/equity/emini-sp-small600.html
