Hello Facundo,
I would wait to see at least 5 trades. And what I normally do is not to remove strategies from the Demo account where I test the EAs.
I put in the live account the Top EAs, for example, having Profit Factor above 1.2 and min count of trades 5. but I keep trading the Demo account. Because some strategies that are losing at the beginning will turn out to be positive. And there might be potential in them.
