Hello,
The endpoint GET /wapi/v3/tradeFee.html (https://binance-docs.github.io/apidocs/spot/en/#trade-fee-user_data) returns negative maker fees for some pairs (BUSD and EUR pairs for example).
However, trades both from the website and the API are processed with 0 fees but not negative fees.
Would it be possible to enlight me?
Note: I tried with fees in the base currency and in BNB, both gave 0 fees.
