Dear Bitget users:
The following text is about Fund Fee
1. Introduction of Fund Fee
Fund fee is the core operating mechanism of Bitget perpetual contract.
The setting of the fund fee aims to ensure that the transaction price of the perpetual swap contract closely follows the underlying reference price through the regular exchange of fund fees between the long and short parties.
2. Description of Fund Fee
1）Bitget does not charge any fundfee, which are previously collected by users.
2）Fund fee is generated every 8 hours, which are 07:00, 15:00, 23:00 (UTC+08:00), you only need to pay or charge fees if you hold a position at the time of these three fund timestamps.
3. Calculation of FundFee
1）The calculation formula for the fundfeeyou received or paid is as follows:
Fund Fee = Fund rate * Position value
The value of your position has nothing to do with leverage, not based on how much margin you have allocated for the position:
USDT margined contract position value = face value * number of contracts * latest marked price
Inverse contract position value = face value * number of contracts / latest marked price
2）Among them, the calculation formula of the fund rate is as follows:
Fund rate (F) = Premium index (P) + clamp (interest rate (I)-premium index (P), 0.05%, -0.05%)
When the fund rate is positive, the long pays the short; when the fund rate is negative, the short pays the long.
The interest rate depends on the base currency and the borrowing rate of the pricing currency itself.
Interest rate (I) = (quoted interest rate index-base interest rate index) / fund rate interval
Premium Index (P) = (Max(0, depth-weighted bid price-marked price)-Max(0, marked price-depth-weighted selling price))/spot price + fair spread of marked price
