Just a simple question. How long have you been trading forex, Nina?
I am afraid you're a bit overjoyed with what you have discovered. You have discovered one "naked" MA reverse system. The fact you got some pips for three days is a great one on condition that you'll drop trading and take some other job. Buy if you want to keep it on then be prepared for a good roller coaster ride one day or two days, or three... unless, of course, you have enough to pay for that.
Cheers,
