Will holding a perpetual contract without selling it incur fees?
There is a funding rate 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 according to the market's long and short ratio.
The funding rate is settled three times a day, at 0:00, 8:00, and 16:00.
Positions held at the settlement time will be settled.
If the funding rate is positive, holding long positions pays money, and short positions receive money.
If the funding rate is negative, holding short positions pays money, and long positions receive money.
The funding fee is exchanged between the market's long and short players.
The calculation for the funding fee: Position value × Funding rate.
If you plan to hold long-term, the funding fee can also be a significant expense.
