I also trade DAX and FTSE CFD Index's on top of Gold & 21 pairs. I must say the only reason I look at them is because they go wild in my London trading session so why not take a trade or two on occasions. But I only trade index's on M1 and if I am in the mood.
Here was a DAX trade two days back using normal price action order flow plus trend lines used as a stop loss in an attempt to make sense of this wild time frame.
