Funding fee annual return conversion

I have displayed the funding fee for BTCUSDT and BTCUSD and calculated its cumulative value. The funding fee operates differently depending on the direction of the held position. If a low-leverage short position is maintained in the long term, the funding fee can function as a hedging tool. In other words, it can offset or mitigate the risk of the short position's base price rising. On the other hand, During the maintenance of the long position, the funding fee can work as a cost.
