i trade them - sometimes (specially during news) they have larger spikes then currency - this can be your advantage bc in 10sec you can make lots $$$ (well only if you are on the correct side ...)
suggestion: 2min before news put an oco sell order 80-100 pips above, and buy order 80-100 pips below the current price
if there is a fill you close immediately on the retracement
specially on /DX it work quite well bc is rare that it take a direction and continues
