Are there major differences between typical price action of eur/usd and aud/usd? Does one trend more than the other, is one more volatile? I'm not looking for opinions, I'd just like to find out if there is already well known and irrefutable evidence regarding differences in their price action that I'm not aware of. I just noticed that moving average crossovers really stink in aud/usd, there are way too many whipsaws compared to eur. Is this just random or can a strategy be devised from this idea?
