Binance's fees are not clear enough, it is recommended to learn from the display of OKEx

I found a serious problem. According to Doubao's calculation of the handling fee, I looked at it and found that I played exactly 100 games yesterday, all of which were high positions. 100U*100 times=10000u, and the handling fee for one game is 4u or 2u. For 100 games, I paid nearly 400U in handling fees. This is the case regardless of winning or losing. I feel a little messy 😁 I lost all my pants working for the boss all night. Is there any big brother who can tell me how to calculate it?

Specific handling fee algorithm
(The transaction fee also follows the Maker-Taker model. The Maker (order placing) fee rate is generally 0.02%, and the Taker (order taking) fee rate is generally 0.04%. For example, for a leveraged transaction of 10,000USDT, the maker fee is 10,000×0.02%=2USDT, and the taker fee is 10,000×0.04%=4USDT.)
