Advanced Backtesting Analysis
Analyze the buy/entry and sell/exit tags
It can be helpful to understand how a strategy behaves according to the buy/entry tags used to mark up different buy conditions. You might want to see more complex statistics about each buy and sell condition above those provided by the default backtesting output. You may also want to determine indicator values on the signal candle that resulted in a trade opening.
!!! Note The following buy reason analysis is only available for backtesting, not hyperopt.
We need to run backtesting with the --export
option set to signals
to enable the exporting of
signals and trades:
freqtrade backtesting -c <config.json> --timeframe <tf> --strategy <strategy_name> --timerange=<timerange> --export=signals
This will tell freqtrade to output a pickled dictionary of strategy, pairs and corresponding
DataFrame of the candles that resulted in buy signals. Depending on how many buys your strategy
makes, this file may get quite large, so periodically check your user_data/backtest_results
folder to delete old exports.
Before running your next backtest, make sure you either delete your old backtest results or run
backtesting with the --cache none
option to make sure no cached results are used.
If all goes well, you should now see a backtest-result-{timestamp}_signals.pkl
file in the
user_data/backtest_results
folder.
To analyze the entry/exit tags, we now need to use the freqtrade analysis
command:
freqtrade analysis -c <config.json> -s <strategy_name> --analysis_groups 0,1,2,3,4
The --analysis_groups
option is used to specify the various tabular outputs, ranging from the simplest (0)
to the most detailed per pair, per buy and per sell tag (4). More options are available by
running with the -h
option.
Tuning the buy tags and sell tags to display
To show only certain buy and sell tags in the displayed output, use the following two options:
--enter_reason_list : Comma separated list of enter signals to analyse. Default: "all"
--exit_reason_list : Comma separated list of exit signals to analyse. Default: "stop_loss,trailing_stop_loss"
For example:
freqtrade analysis -c <config.json> -s <strategy_name> --analysis_groups 0,1,2,3,4 --enter_reason_list "enter_tag_a,enter_tag_b" --exit_reason_list "roi,custom_exit_tag_a,stop_loss"
Outputting signal candle indicators
The real power of freqtrade analysis
comes from the ability to print out the indicator
values present on signal candles to allow fine-grained investigation and tuning of buy signal
indicators. To print out a column for a given set of indicators, use the --indicator-list
option:
freqtrade analysis -c <config.json> -s <strategy_name> --analysis_groups 0,1,2,3,4 --enter_reason_list "enter_tag_a,enter_tag_b" --exit_reason_list "roi,custom_exit_tag_a,stop_loss" --indicator_list "rsi,rsi_1h,bb_lowerband,ema_9,macd,macdsignal"
The indicators have to be present in your strategy's main DataFrame (either for your main timeframe or for informative timeframes) otherwise they will simply be ignored in the script output.
