DAX ETF on the AMEX, but very low volume. Over the last 20 trading days, DAX futures have had average daily range of 2.3% versus 2.1% for ES, 2.5% for NQ and 2.6% for ER2. Not all that different.
Dax is just another index future , it may seem a volatile beast but in my opinion is no different to the ES , in that the index movement is based on the underlying stock movement , if you know how the underlying stocks moves the dax futures is not so scary , if you have a way of looking at the tick index , advance/decline issues and advance/decline volume and other breadth measures you will have a better understanding of its movement. I would say you get more bang for your buck with the dax than the ES simply because of the minimum tick size relative to the daily range . ..
