@ Subagya:
As far as I know, if you offer copy trade services to a broker, the commission per trade will be determined by the broker.
Answer to Subagya:
There are several brokers that provide copy trade services with commissions determined by the signal provider. Some popular examples in this regard are eToro, ZuluTrade, and Myfxbook Autotrade.
You can also use the traders family copytrade program and you can determine the amount of fee per person to subscribe to your account.
