#### Supplying custom fee value
Sometimes your account has certain fee rebates (fee reductions starting with a certain account size or monthly volume), which are not visible to ccxt.
To account for this in backtesting, you can use `--fee 0.001` to supply this value to backtesting.
This fee must be a percentage, and will be applied twice (once for trade entry, and once for trade exit).
```bash
freqtrade backtesting --fee 0.001
```
#### Running backtest with smaller testset by using timerange
Use the `--timerange` argument to change how much of the testset you want to use.
