If perpetual contracts are held without selling, or not sold, will there be any costs incurred?
In perpetual contracts, there is a funding rate
It is generally displayed in the upper right corner of the order book
By default, it is 0.01%, 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 incurs costs, while short positions gain money
If the funding rate is negative, holding short positions incurs costs, while long positions gain money
The funding fee is given by the market participants who are long and short
The calculation method for the funding fee: position value × funding rate
If you plan to hold for the long term, the funding fee can also be a significant expense
