Hey John,
Welcome to the Forum. I would suggest you trade at least 3 currency pairs. And why USDCHF exactly?
What is your rule to move the EAs from Demo to Live and from Live back to Demo?
Most importantly did you check if you have the same results on Demo and Live? When you place one EA in the live account, do you keep trading it in the Demo, and do you see the same results? Do the trades match?
Let me know so I can give you some tips.
