Hi all,

I have been using the last few days creating a strategy, and I noticed something very odd.

Using the strategy on an FX pair from 2010 to now, I got -37% return. So I thought, why not just reverse it with SELL when it was BUY and BUY when I had sell. Then I should have made +37%, right?

But when reversing, it suddenly got -77%! Really not sure why this is happening?!

Also seems like the algo is overtrading. One element is trade when 13 EMA cross 21 EMA. But it trades even when its not crossing and I have checked with many price providers and charts...  I don't understand whats happening, can someone explain it to me?
