Let me just state for the record: there is no causal similarity or correlation between trading ANY FX trading strategy and the spread trading system I teach clients. For the record. On occasion, we will take an intermarket spread like Canadian Dollars versus WTI Crude Oil. Very seldom. In fact, most clients prefer to stay with intramarket spread strategies. I have received a few PM's asking me about FX pairs... good luck and I am not your mentor.
FX is flat price risk or worse (rigged) - i cannot recall recommending one currency versus another... In terms of how I want my clients to risk their own capital I cannot contemplate FX as offering any sort of individualististic, retail-friendly edge,
