I suggest you pay attention to my friends, and check how much trading fees you have incurred in the last three months.

The method is as follows:

Click on assets in the lower right corner, then to the right of the overview there is a contract menu bar, click on contracts, and then click on the small arrow next to today's realized losses.

Then check the funding costs and trading fees.

My trading fees for three months are about 9200 USD, which is shocking, equivalent to what my wife sends to my sister as her annual salary.
