Under the Referrals tab, on the 'Referrers' side, you will see the total traders referred, the total trading volume of those referred traders, and then the total rebates earned from that volume.
You can create as many Referral Codes as you want, and you can keep track of the number of traders, total volume, and total rebates earned through each code.
