MarkUp accounts are accounts with increased commissions. The possibility of opening such accounts is created for clients who have a partner (agent), who provides exclusive support for their referrals or provides them with additional services, for example, conducts personal training sessions, provides expert advisors, etc.
By creating a MarkUp-account, the referred client at will increases the amount of commission charged for opening/closing of transactions on his trading account by several times (from 2 to 20), due to which his partner (agent) receives a larger referral fee.
