The situation is the following. If a client has a deposit with one of the supported brokers, then you won't be getting a commission for them. This was quite expected as after all the goal of the affiliate program is to attract new clients. There is a workaround I will test, and starting the process from zulutrade site with zulu affiliate links, the investor although having an account with the broker open a new one with different email on zulutrade, then go to broker for activation and then connect to zulutrade for copytrading, this might work I believe, but investors might not like the idea to have a different email on those 2 businesses.
