Hello,
The documentation of the endpoint GET /wapi/v3/tradeFee.html (https://binance-docs.github.io/apidocs/spot/en/#trade-fee-user_data) states Fetch trade fee, values in percentage..
However, the actual result is not in percentage.
Example: {‘maker’: -0.0004, ‘symbol’: ‘ZILBUSD’, ‘taker’: 0.0008}
I would suggest to fix the documentation.
