I generally put in a breaking point of 200 ticks for gold (and a stop of 80) - it moves that much a few times each month. I attempt and catch them everything except clearly I don't generally succeed! I get a great deal of 30 - 50 pip misfortunes yet generally make a benefit.
I exchange the cross on the 10 and 18 MA on the 30 minute diagram - it crossed more than two hours before the enormous fall. Obviously, it was to some degree fortunate that it crumbled 270 pips in a single hour...
