Just for the heck of it I'm posting XAUUSD M15 at the closing of the week, a while ago. Real choppy, but the system seems to hold its ground. Following the rules, of course in Demo mode, it manages to get 5 potential trades and 1 that is a probable small loss. Lots of potential pips.
Now, this is only looking at technical indicators and a set of entry/exit rules. Trading is a lot more, as we all know. But it's interesting to try and test.
Maybe it can be made profitable!
