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.
Backtesting will use the crypto-currencies (pair) from your config file
and load static tickers located in
/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)
python3 ./freqtrade/main.py backtesting --realistic-simulation
With 1 min tickers
python3 ./freqtrade/main.py backtesting --realistic-simulation --ticker-interval 1
Reload your testdata files
python3 ./freqtrade/main.py backtesting --realistic-simulation --refresh-pairs-cached
With live data (do not alter your testdata files)
python3 ./freqtrade/main.py backtesting --realistic-simulation --live
For help about backtesting usage, please refer to Backtesting commands.
Understand the backtesting result
The most important in the backtesting is to understand the result.
A backtesting result will look like that:
====================== BACKTESTING REPORT ================================
pair buy count avg profit % total profit BTC avg duration
-------- ----------- -------------- ------------------ --------------
BTC_ETH 56 -0.67 -0.00075455 62.3

BTC_POWR 35 0.98 0.00064887 45.3
BTC_ADA 43 -0.39 -0.00032292 55.0
BTC_XMR 40 -0.40 -0.00032181 47.4
TOTAL 419 -0.41 -0.00348593 52.9
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%).
"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.

Great, your strategy is profitable. What if the bot can give your the
optimal parameters to use for your strategy?
