Fee Benefits	During the voucher validity period, Futures trading fees are calculated based on the displayed discount or fee-offset rules. The exact benefit structure depends on the event.
Cashback Crediting	After the voucher is reclaimed and settlement is completed, eligible cashback will generally be credited to your Spot Account by approximately 02:00 (UTC+8) on the following day (T+1).

How to Claim & Use Prime Bonus

Claim LBank Prime Bonus

Go to the Voucher Center to check whether you have an available LBank Prime Bonus voucher. You may also obtain one by participating in relevant events through LBank Event Center.
Review the voucher amount, claim deadline, validity period, fee benefit, and loss cashback ratio.
When you have no open positions and meet the event eligibility requirements, click Claim. Once successfully claimed, the voucher will appear under the「In Use」tab.

Use Prime Bonus to Open or Increase a Position

Transfer your own funds into your Futures Account. Ensure that the account has both available principal and available Prime Bonus.
Go to the Perpetual Futures trading page to open or increase a position. The system uses your principal first, then applies eligible Prime Bonus toward the margin calculation.
On the order confirmation page and in your position and order details, you can view how your available funds and LBank Prime Bonus are applied to your position.

📌Important: You cannot open a new position if your Futures Account only has Prime Bonus and no available principal. Please transfer funds into the account first, or close positions before proceeding.

Fee Benefits & Loss Cashback

Futures Trading Fee Benefits:

During the voucher validity period, eligible Futures trading fees may receive a discount or offset based on the voucher rules.
For example, with a 10% fee discount, if the original trading fee is 100 USDT, you will pay 90 USDT and save 10 USDT. The actual fee paid after the discount is also used as the basis for referral commission calculations.

Estimated Loss Cashback:

The voucher calculates Estimated Loss Cashback based on the net losses from eligible trades made after the voucher is claimed, using the specified cashback ratio.
This amount may change in real time based on:

Realized PnL
Unrealized PnL from open positions
Fee benefits already received

Estimated Loss Cashback is provided for reference only. The final amount is determined when the Prime Bonus is reclaimed and settled.

Calculation Item	Rules
Cashback Formula	Final Loss Cashback = max[0, min((Net Loss During the Event Period − Fee Benefits Already Received − Prime Bonus Still Used by Open Positions at Settlement) × Voucher Cashback Rate, Voucher Face Value)] Here, min returns the lower value, and max returns the higher value.
Cashback Cap & Deductions	The amount calculated from your net losses and cashback rate is capped at the voucher face value. Fee benefits already received and any Prime Bonus still used by open positions at settlement are then deducted. The final cashback cannot be less than zero.
Calculation Example	Suppose your net loss during the event period is 100 USDT, the voucher cashback rate is 33%, and the voucher face value is at least 33 USDT. If you have saved 5 USDT in trading fees and no Prime Bonus is being used by open positions at settlement, your final cashback is: (100-5-0) x 33%=31.35USDT
Extreme Market Conditions	If your account experiences negative equity, losses exceeding the amount borne by your actual principal are excluded from the cashback calculation basis.

Prime Bonus Reclamation & Settlement

LBank Prime Bonus may be reclaimed by the system in cases including voucher expiration, transferring funds out of the Futures Account, negative equity, liquidation of all cross-margin positions, or risk-control measures.
At the time of reclamation, the system settles the voucher based on the account’s PnL and Prime Bonus usage status.

Scenario	Prime Bonus Treatment	Event/Cashback Status
You manually close a position	The Prime Bonus used by that position returns to your available position balance.	The event remains active, and the bonus may be used again to open positions.
Partial liquidation or liquidation of an isolated position	The Prime Bonus used by the liquidated position is partially reclaimed.	Remaining Prime Bonus remains available, and the event continues.
Voucher expiration or funds transferred out of the Futures Account	The entire voucher enters the reclamation and settlement process. Unused Prime Bonus is reclaimed first.	The event ends, and final cashback is settled according to the applicable rules.
Negative equity, liquidation of all cross-margin positions, or risk-control reclamation	All Prime Bonus is reclaimed. Any portion still used by open positions will be handled after the positions are released.	The event ends. No loss cashback is provided in cases of risk-control reclamation.

📌Important: Transferring funds out of your Futures Account triggers Prime Bonus reclamation, while transferring funds into the account does not. To avoid affecting final cashback settlement, it is recommended that you close your positions before the voucher expires.
