What Is a Contract Trading Trial Fund?
A Contract Trading Trial Fund is a voucher designed to let more users enjoy contract trading for free. It can be used to offset trading fees, funding fees, or losses.
Once the eligibility requirements are met, the trial fund will be issued in the form of a voucher.
It will be delivered directly to the Voucher Center on both the website and the app.
After you claim the trial fund, it will be automatically credited to your contract trading account.
How to Find Your Trial Fund
Web: Voucher Center → Contract Trial Fund
Top-up of Trial Fund
After successfully claiming your Contract Trial Fund, you must top it up into your contract account before you can use it. For certain trial funds, the amount you can top up will depend on the amount of real funds in your account.
Which trial funds require a top-up?
In the Coupon Center, if you see the note “1 USDT of real funds can top up xx USDT of trial funds” on your trial fund, it means that this coupon requires a certain amount of real funds in your contract account.
Real funds: The amount in your contract account excluding trial funds; it only includes deposits and transfers, and does not count unrealized PnL.
How to calculate the maximum top-up amount of trial funds?
Top-up amount of trial funds = Real funds in contract account × ratio − Existing trial fund amount
For example, as shown in the figure below:
Example:
User A’s contract account balance (excluding trial bonus) = 5 USDT, and they already have 3 USDT of trial bonus in their contract account.
If the voucher states “1 USDT of real funds can deposit 3 USDT of Contract Trial Bonus,” then the total depositable trial bonus amount for User A = 5 × 1 = 5 USDT.
After calculating the total depositable amount, you must subtract the trial bonus already in the account.
Tip: The deducted trial bonus includes both available and frozen amounts. That is, as long as the trial bonus has been deposited into the contract account but not yet fully used for deductions, it will be counted.
Since User A already has 3 USDT of trial bonus in their contract account, the final depositable amount = 5 − 3 = 2 USDT.
Additional Notes on Deposits
You must manually confirm the use of the trial bonus before making a deposit.
Trial bonuses with different deduction ratios cannot be used at the same time; attempting to use bonuses with different ratios will cause the currently active bonus to become invalid, which may result in forced liquidation risk.
Contract Trial Bonus Deduction Rules & Restrictions
When conditions are met, the trial bonus will be deducted according to the set ratio:
Funding Fee Deduction
When a funding fee is generated during your contract trading, the trial bonus will be used first according to the deduction ratio until the trial bonus balance is insufficient.
Transaction Fee Deduction
When a trading fee is generated during your contract trading, the trial bonus will be used first according to the deduction ratio until the trial bonus balance is insufficient.
Closing Loss Deduction
To deduct losses (actual account losses) at closing according to the deduction ratio, the following condition must be met:
(Current Equity at Closing − Trial Bonus Balance − Cumulative Deposits) < Initial Principal
Current Equity at Closing = Contract wallet balance + Unrealized P&L
Initial Principal: Recorded at the time of receiving the trial bonus; equals contract wallet balance (excluding trial bonus) + unrealized P&L; trial bonus is not counted.
Cumulative Deposits (transfers to contract account): Recorded from the time of receiving the trial bonus to closing; includes the total transferred from other wallets to the contract wallet.
Forced Liquidation Fee Deduction
When a forced liquidation fee is generated during your contract trading, the trial bonus will be used first according to the deduction ratio until the trial bonus balance is insufficient.
Opening Margin
The trial bonus can be used as part of the opening margin, but cannot be used alone to open a position; it must be combined with real funds.
Example: If the account’s remaining available funds of 10 USDT are entirely trial bonus, it cannot be used as opening margin.
Orders that use futures trial funds or futures discount coupons for offsetting will not be eligible for rebates during the offset period and within the scope of the corresponding orders. Please refer to the coupon terms and the event page for specific rules.
Trial Bonus Expiration
The trial bonus will expire when it reaches the expiration date.
If an open position/order is using the trial bonus, the expiration date will be extended to prevent user losses.
If the user forcibly transfers funds while holding a trial bonus, the bonus will become invalid and may trigger liquidation.
Priority Use of Funds & Trial-Funds Recall Rule
When an account holds both own funds and trial/bonus funds, the system will prioritize using own funds to open positions. If a subsequent risk check shows that, after excluding the trial/bonus funds, the account’s overall margin ratio falls below 80%, the trial/bonus funds will be recalled immediately. This recall can instantly reduce account equity, raise position risk and push up the liquidation price, potentially causing unexpected liquidations. We recommend keeping sufficient own margin or reducing position size to avoid this risk.
