A negative fee means that you will receive a rebate. Funding rates change based on market lending rates.
In the Perpetual Contracts, funding is exchanged between standing long and short positions over discrete Funding Intervals. You can check your Trade History to see the positive amount you paid for that Funding Interval or the negative amount you received. BigONE does not charge any fees on funding paid or received.
