In addition to the handling fee, contract users also have a large expense.
This is the funding fee in the perpetual contract.
It is usually displayed in the upper right corner of the order book.
The default is positive 0.01%, which is adjusted at any time according to the long-short ratio in the market.
The funding rate is settled three times a day, at 0 o'clock, 8 o'clock, and 16 o'clock.
The position will be settled only if it is held at the settlement time.
If the funding rate is positive, long orders will be paid, and short orders will be paid.
If the funding rate is negative, short orders will be paid, and long orders will be paid.
The funding fee is given by the long and short players in the market.
The calculation method of the funding fee is: position value × funding rate.
If the position is held for a long time, the funding fee is also a considerable expense or profit.
