# Fees

Waves.Exchange charges fees for transactions, such as placing trading orders, sending assets (between Waves.Exchange accounts) and sending assets via gateway (from Waves.Exchange accounts to external blockchains).

# Trading Fee

In Waves.Exchange the fixed 0.003 WAVES base fee is charged for placing a buy/sell trading order, regardless of the amount of the future deal. An order can be fully executed by a transaction, in this case the full fee is included in that transaction. An order can be partially executed by a transaction, in this case the fee is included in that transaction proportionally to the executed amount.

Trading fee can be paid in WAVES or other assets supported by the exchange. Trading fee paid in asset other than WAVES is calculated by the following formula: BASE_FEE*FEE_ASSET_RATE. The result is rounded up to number of decimals of the fee asset (AssetDecimals).

You can get current rates of the assets (FEE_ASSET_RATE) with GET /matcher/settings/rates matcher API method.
