When simulating a strategy using the backtest feature, it is important to factor in exchange fees in order to more closely replicate real-world conditions. The Backtest-Only Settings under Parameters allow you to configure these values, which only affect backtest results and are not used in live trading mode.
The available fields are:
- Maker Fee: This is the fee your exchange charges for putting orders on the book. In order words, the fee typically paid for limit orders.
- Taker Fee: The fee charged by your exchange for taking orders from the book or market order.
Note: Default values are typical make/taker fees charged by exchanges, feel free to adjust these values per your exchange's fees.
In live trading mode, these fields have no effect as you will pay the fees according to your exchange's schedule. Some exchanges charge fees in quote currency, while others in base currency. In backtest results, fees are always taken in quote currency.
