How Spot Trading Commission Rates Are Structured and Calculated
Summary
The document explains three spot-trading fee categories: standard commissions, tax commissions, and special commissions. It distinguishes account and symbol rate queries, which show current rates and buyer or seller components, from a test-order calculation that returns rates specific to an order and does not list buyer and seller components separately. Its worked example calculates fees for a market sell by combining the taker rate with the seller rate and applying the result to the trade’s notional value.
It also describes paying fees in the proceeds currency or, when account and symbol settings permit and the balance is sufficient, in BNB. The example converts fees using an assumed exchange rate and applies a discount only to the standard commission; tax and special commissions remain undiscounted. These are illustrative figures, explicitly fictional and limited to spot trading, so actual rates and applicable settings must be checked for the relevant account and order.
Key ideas
- Spot fees can include standard, tax, and special commission components.
- A test-order calculation reports rates for a specific order, while an account query reports current symbol rates with buyer and seller components.
- For a sell, the example calculates commission using notional value multiplied by the taker and seller rate components.
- When eligible, BNB can be used to pay fees, but the illustrated discount applies only to standard commission.
- If the BNB balance is insufficient, the example says fees are deducted from the proceeds currency.
