If I can intraday position trade one market profitably, but it is a pain in the ass (London hours forex majors from east coast USA), and I believe I have opportunities to trade for a living in other markets (US hours), is the learning curve going to be incredibly steep if I change gears? All my entries/exits are swing points, trend lines, break outs, yadda yadda. I just try to figure out if its going up or down as painlessly as possible on the risk/reward front. This stuff seems like it would be universal. Anyone been there and done that? So, um, reassure me that markets are markets.
