How IB commission works
When a client referred by an IB opens an account and trades, the IB earns commission for each lot traded. This commission is paid by the broker from the spread or from its revenue — it does not increase the client trading costs (the spread is the same whether or not the client was referred by an IB).
Transparency requirement
Any website, publication, or EA catalogue that participates in a broker IB programme has a material financial interest in recommending those brokers. mt5depot participates in IB programmes for the brokers listed in this catalogue. This is disclosed in the affiliate disclosure page and on every broker listing page.
IB vs affiliate
Technically, an introducing broker has a formal regulatory relationship with the broker and may be required to be licensed; an affiliate is purely a marketing referral arrangement. Many programmes blur this distinction.
