How Spot Trading Commissions Are Calculated Across Fee Types

Summary

This documentation explains spot trading commissions as the combination of standard, tax, and special rates. It distinguishes account commission queries, which report current rates for a symbol and include maker, taker, buyer, and seller components, from test order calculations, which provide rates specific to an order and account for its side. It then walks through a sell order example, calculating fees against the received notional amount using the applicable taker and seller rates.

The example also shows how eligible standard fees may be converted to a discount asset and reduced when account and symbol discounts are enabled, while tax and special charges remain undiscounted. If the account lacks enough of the discount asset, fees are instead deducted from the proceeds. The stated rates and prices are fictional and apply only to spot trading; actual rates may vary with promotions, discounts, order details, and exchange conditions. The page describes fee mechanics, not trading performance.

Key ideas

• Spot commissions can include standard, tax, and special fee components.
• The fee calculation uses maker or taker status together with buyer or seller rates.
• For a sell order, the example applies the fee rates to the notional proceeds.
• An eligible discount asset can reduce standard commission, but not tax or special commission.
• If the discount asset balance is insufficient, fees are deducted from the received asset instead.
