Yes, for the full version, you can modify everything, which mean, you are free to change every input of the EA. All broker are suitable for this EA, but, I strongly recommend you to use a broker that have smaller spread, such as the OctaFX. And yes, for the payment, you can transfer through this email, firstname.lastname@example.org.
I have a broker that have different arbitage, that for me, is really freaking good, profit that you might get through this broker reach 100%. But I do not recommend to buy this EA, because every broker that are using this EA, your account will only last for around one or two months only, the broker will block your account within the period. The reason for that to happen is, this EA is too hyperactive.
