Users who sign up can receive a percentage discount on their trading fees. In the plugin configuration, you can specify whether only users who join with a referral code will receive the discount. This is advantageous because it encourages users to refer others to sign up, which in turn helps grow the user base and potentially leads to more benefits for all users.
After installing the user promo plugin, you need to configure the following items in the public section.
discount_period: The number of months that the discount rates will apply to referred users. Set to "0" for no discount expiry.default_discount_rate: The discount rate (in percentage) to apply to new users. The range for this value is [0 ≤ x ≤ 100].affiliation_discount_rate: The discount rate (in percentage) to apply to new users who used an affiliation link. The range for this value is [default rate < x ≤ 100].
