I'll say, because I do not have much credit on this subject, but I suggest that much attention has to be paid on the currency pairs traded. For example, USDJPY, and USDCHF seems to be tricky ones. Seems that the moves are stable only in higher time frames, say D1 and weekly time frame. That is way too slow for me, too. However, there are currency pairs, which have nice smooth behavior in lower time frames, such as H1 and H4.
