How much does code PRO save you?

Every leverage trade on GMX pays a position fee when you open and again when you close — roughly 0.05% to 0.07% of your position size per side, depending on whether your trade balances or worsens the open-interest skew. The calculator above uses this figure because it's the fee the referral discount actually reduces.

Two other costs are charged separately and are not discounted by any referral code: a borrow fee that accrues for as long as you hold a leveraged position, and a funding fee exchanged between long and short traders depending on which side is more crowded. Knowing the difference matters: the 10% code saves you on entry and exit, not on how long you keep a position open.

You register the code PRO once on GMX's Referrals page. From then on, the discount is deducted from your position fee automatically at the moment each trade executes — there's no rebate to claim and nothing to track. The 10% applies for the life of the account, on every eligible trade.

Because the saving is a fixed percentage of the fee, it scales directly with how much you trade. A casual trader saves a little; an active trader moving six or seven figures of volume a month saves a meaningful amount over a year — all from entering one code.

The code costs nothing and takes under a minute to register, so the only real question is whether 10% off fees is material to you. For occasional trades it's a small, pleasant discount. For anyone trading with size or frequency, fees are one of the few costs you can control directly — and cutting them by the maximum the protocol allows is the simplest edge available. There is no downside: you receive the full discount whether or not the site sharing the code earns a rebate.
