Referral code

Also written or said as: referral, ref code, referral link, invite code

A code or link from an existing user that can lower your trading fee and pays them a share of it.

Many trading apps cut your fee a little if you sign up with someone's code, and pay part of your fees to whoever referred you. That is why so many posts end with a referral link. Using one is fine, but pick a platform for its features and safety, never for the code.
