Hi Wawa,
Why is it that you think the BTC EA is trading XAU??
It looks to me that the BTC Ea just hasn’t made any trades yet which is highly likely on an H1 EA that has only been on demo for a couple of days.
IF you closed all your trades and chart and then ONLY had a single Chart open that was BTC with the BTC EA then I would believe it’s trading a different currency.
I am however very sure that is not what is happening.
Also it doesn’t matter what the EA says (ie wether it is for BTC or XAUUSD) it is the chart it is attached to that will be traded.
