how the exchange deceives me.

I have 1.19 USDC left in my futures balance.

I opened a position unsuccessfully.

Closed with a loss of 0.04 USDC.

As you know, the maker's fee is absent on USDC. And then I saw 1.12 USDC in my balance. In total, I checked the position history and saw -0.05. Well, okay. At closing, it slides. Yes, let it be, but 1.19 minus 0.05 is 1.14... but not 1.12. Where did the 0.02 go? Fee? So, the maker's fee is 0% and the taker's fee has a 40% discount.
