yes GG, I do ok playing Cable, it's certainly how I earn me crust anyway. Occasionally have a wander onto Swissy or CAD, but only if they're setting up on a key level, and then mainly intraweek/swing rather than intraday.
as you say, Cable offers pretty decent avg daily ranges (beginning to expand entering this quarter), reacts well off the round numbers/patterns & heavily traded on the spot. Bit of all sorts really, in all occasions!
I guess the strat(s) determines the overall effectiveness etc....but then, that's the case with any instrument!
