Ok, Ive been trying this system. I just buy both EUR/USD and CHF/USD at the same time. Ive been trialling this since the it was first posted.
I have had a 100% success rate. My demo account has doubled. Most of the trades have taken at least 3-4 days with the last one being over a week.
the worst situation I have been in was 100 pips down but then it soon went into positive territory again.
Saying all this, I will still continue to trial this as I am not yet convinced. I'm sure that soon something detrimental will happen to my account because this is just too easy.....
I will continue for another 3 months before considering this in a live account...
