I have been trying to reconcile a massive difference in my observed balance and that which is calculated from a transaction history of isolated margin trades.
Hi there, when the BNB is enabled to pay for trading fees, “commissionAsset” will list BNB.
Your trade happened at “time”: 1614243532493 (25 February 2021) and your sheet screenshot lists “BNB deducts fee” in the earliest at 11 of March 2021, maybe before 11 of March 2021 you weren’t using BNB for trading fee yet?
Do you have spotBNBBurn enabled when you query POST /sapi/v1/bnbBurn?
