## Test your strategy with Backtesting
|
|
Now you have good Buy and Sell strategies, you want to test it against
|
|
real data. This is what we call
|
|
[backtesting](https://en.wikipedia.org/wiki/Backtesting).
|
|
|
|
|
|
Backtesting will use the crypto-currencies (pair) from your config file
|
|
and load static tickers located in
|
|
[/freqtrade/tests/testdata](https://github.com/gcarq/freqtrade/tree/develop/freqtrade/tests/testdata).
|
|
If the 5 min and 1 min ticker for the crypto-currencies to test is not
|
|
already in the `testdata` folder, backtesting will download them
|
|
automatically. Testdata files will not be updated until you specify it.
|
|
|
|
The result of backtesting will confirm you if your bot as more chance to
|
|
make a profit than a loss.
|
|
|
|
|
|
The backtesting is very easy with freqtrade.
|
|
|
|
### Run a backtesting against the currencies listed in your config file
|
|
**With 5 min tickers (Per default)**
|
|
```bash
|
|
python3 ./freqtrade/main.py backtesting --realistic-simulation
|
|
```
|
|
|
|
**With 1 min tickers**
|
|
```bash
|
|
python3 ./freqtrade/main.py backtesting --realistic-simulation --ticker-interval 1
|
|
```
|
|
|
|
**Reload your testdata files**
|
|
```bash
|
|
python3 ./freqtrade/main.py backtesting --realistic-simulation --refresh-pairs-cached
|
|
```
|
|
|
|
**With live data (do not alter your testdata files)**
|
|
```bash
|
|
python3 ./freqtrade/main.py backtesting --realistic-simulation --live
|
|
```
|
|
|
|
For help about backtesting usage, please refer to
|
|
[Backtesting commands](#backtesting-commands).
|
|
|
|
## Understand the backtesting result
|
|
The most important in the backtesting is to understand the result.
|
|
|
|
A backtesting result will look like that:
|
|
```

|
|
|
|
The last line will give you the overall performance of your strategy,
|
|
here:
|
|
```
|
|
TOTAL 419 -0.41 -0.00348593 52.9
|
|
```
|
|
|
|
We understand the bot has made `419` trades for an average duration of
|
|
`52.9` min, with a performance of `-0.41%` (loss), that means it has
|
|
lost a total of `-0.00348593 BTC`.
|
|
|
|
As you will see your strategy performance will be influenced by your buy
|
|
strategy, your sell strategy, and also by the `minimal_roi` and
|
|
`stop_loss` you have set.
|
|
|
|
As for an example if your minimal_roi is only `"0": 0.01`. You cannot
|
|
expect the bot to make more profit than 1% (because it will sell every
|
|
time a trade will reach 1%).
|
|
```json
|
|
"minimal_roi": {
|
|
"0": 0.01
|
|
},
|
|
```
|
|
|
|
On the other hand, if you set a too high `minimal_roi` like `"0": 0.55`
|
|
(55%), there is a lot of chance that the bot will never reach this
|
|
profit. Hence, keep in mind that your performance is a mix of your
|
|
strategies, your configuration, and the crypto-currency you have set up.
|
|
|
|
## Next step
|
|
Great, your strategy is profitable. What if the bot can give your the
|
|
optimal parameters to use for your strategy?
