How GMX trading fees work
Every leverage trade on GMX pays a position fee when you open and again when you close. Most markets charge 0.04% when a trade improves the long/short open-interest balance and 0.06% when it worsens that balance. Certain TradFi markets use different rates, so the GMX confirmation panel remains authoritative.
Borrowing and funding are separate from the position fee and are not discounted. Under the current GMX model, only the side with larger open interest pays the borrow fee. Funding can be a cost or a credit and adjusts over time with the long/short imbalance. The 10% referral reduction applies to eligible entry and exit fees, not holding costs.
How the PRO discount is applied
Open the official GMX referral link containing code PRO. GMX stores the code in your browser and writes it to the referral contract when your first valid order is created. The eligible discount is deducted from the position fee at execution; there is no separate trader rebate to claim.
Because the saving is a fixed percentage of the eligible position fee, it scales with notional volume. At a 0.06% position-fee rate, a $10 000 operation saves $0.60, a $100 000 operation saves $6 and a $1 000 000 operation saves $60. Borrowing, funding, network fees and price impact remain separate.
Is the saving worth it?
The referral code reduces one part of the total trading cost. It does not make a trade profitable, reduce liquidation risk or lower holding costs. The site may earn an affiliate reward without reducing the trader discount. Rates, code eligibility and program terms can change, so verify the active code and fee breakdown in GMX before submitting an order.

Frequently asked questions
How much can I save with the GMX referral code?
Code PRO applies a 10% discount to eligible opening and closing position fees. At the 0.06% standard rate, a $100 000 open costs $60 before the code and saves $6; opening and later closing the same notional saves an estimated $12 before other costs.
Does the discount apply to all GMX fees?
No. The referral discount applies only to eligible opening and closing position fees. An applicable borrow fee and any funding cost are separate and are not discounted.
Do I need to do anything to claim the saving?
No separate claim is required. Opening the referral link stores code PRO in your browser, and GMX writes a valid code to the contract when you create your first order. The eligible fee discount is then applied automatically.
Is 10% really the most I can save?
Yes, under the current GMX referral tier table. Tier 2 and Tier 3 both give traders 10% off eligible opening and closing fees. Check the live GMX Referrals page because program terms can change.
