!!! Tip "Use multiple configuration files to keep secrets secret"
|
||||
You can use a 2nd configuration file containing your secrets. That way you can share your "primary" configuration file, while still keeping your API keys for yourself.
|
||||
|
||||
``` bash
|
||||
freqtrade trade --config user_data/config.json --config user_data/config-private.json <...>
|
||||
```
|
||||
The 2nd file should only specify what you intend to override.
|
||||
If a key is in more than one of the configurations, then the "last specified configuration" wins (in the above example, `config-private.json`).
|
||||
|
||||
If you used the [Quick start](installation.md/#quick-start) method for installing
|
||||
the bot, the installation script should have already created the default configuration file (`config.json`) for you.

You should also make sure to read the [Exchanges](exchanges.md) section of the documentation to be aware of potential configuration details specific to your exchange.
|
||||
|
||||
!!! Hint "Keep your secrets secret"
|
||||
To keep your secrets secret, we recommend to use a 2nd configuration for your API keys.
|
||||
Simply use the above snippet in a new configuration file (e.g. `config-private.json`) and keep your settings in this file.
|
||||
You can then start the bot with `freqtrade trade --config user_data/config.json --config user_data/config-private.json <...>` to have your keys loaded.

**NEVER** share your private configuration file or your exchange keys with anyone!

!!! Tip "Quickly optimize ROI, stoploss and trailing stoploss"
|
||||
You can quickly optimize the spaces `roi`, `stoploss` and `trailing` without changing anything in your strategy.
|
||||
|
||||
```python
|
||||
``` bash
|
||||
# Have a working strategy at hand.
|
||||
freqtrade hyperopt --hyperopt-loss SharpeHyperOptLossDaily --spaces roi stoploss trailing --strategy MyWorkingStrategy --config config.json -e 100
|
||||
```
|
||||
|
||||
### Hyperopt execution logic
|
||||
|
||||
Hyperopt will first load your data into memory and will then run `populate_indicators()` once per Pair to generate all indicators.
|
||||
|
||||
Hyperopt will then spawn into different processes (number of processors, or `-j <n>`), and run backtesting over and over again, changing the parameters that are part of the `--spaces` defined.
|
||||
|
||||
For every new set of parameters, freqtrade will run first `populate_buy_trend()` followed by `populate_sell_trend()`, and then run the regular backtesting process to simulate trades.
|
||||
|
||||
After backtesting, the results are passed into the [loss function](#loss-functions), which will evaluate if this result was better or worse than previous results.
|
||||
Based on the loss function result, hyperopt will determine the next set of parameters to try in the next round of backtesting.
|
||||
|
||||
### Configure your Guards and Triggers
|
||||
|
||||
There are two places you need to change in your strategy file to add a new buy hyperopt for testing:
|
||||
|
|
@ -187,60 +198,54 @@ There you have two different types of indicators: 1. `guards` and 2. `triggers`.
|
|||
However, this guide will make this distinction to make it clear that signals should not be "sticking".
|
||||
Sticking signals are signals that are active for multiple candles. This can lead into buying a signal late (right before the signal disappears - which means that the chance of success is a lot lower than right at the beginning).
|
||||
|
||||
Hyper-optimization will, for each epoch round, pick one trigger and possibly
|
||||
multiple guards. The constructed strategy will be something like "*buy exactly when close price touches lower Bollinger band, BUT only if
|
||||
ADX > 10*".
|
||||
|
||||
```python
|
||||
from freqtrade.strategy import IntParameter, IStrategy
|
||||
|
||||
class MyAwesomeStrategy(IStrategy):
|
||||
# If parameter is prefixed with `buy_` or `sell_` then specifying `space` parameter is optional
|
||||
# and space is inferred from parameter name.

), 'buy'] = 1
|
||||
return dataframe
|
||||
```
|
||||
Hyper-optimization will, for each epoch round, pick one trigger and possibly multiple guards.
|
||||
|
||||
#### Sell optimization
|
||||
|
||||
Similar to the buy-signal above, sell-signals can also be optimized.
|
||||
Place the corresponding settings into the following methods
|
||||
|
||||
* Define the parameters at the class level hyperopt shall be optimizing.
|
||||
* Define the parameters at the class level hyperopt shall be optimizing, either naming them `sell_*`, or by explicitly defining `space='sell'`.
|
||||
* Within `populate_sell_trend()` - use defined parameter values instead of raw constants.
|
||||
|
||||
The configuration and rules are the same than for buy signals.
|
||||
|
||||
```python

||||
class MyAwesomeStrategy(IStrategy):

Let's say you are curious: should you use MACD crossings or lower Bollinger Bands to trigger your buys.
|
||||
And you also wonder should you use RSI or ADX to help with those buy decisions.
|
||||
If you decide to use RSI or ADX, which values should I use for them?

So let's use hyperparameter optimization to solve this mystery.

### Defining indicators to be used

||||

macd = ta.MACD(dataframe)

||||
dataframe['macd'] = macd['macd']

||||

||||
dataframe['macdhist'] = macd['macdhist']

||||

||||

||||

||||

conditions.append(qtpylib.crossed_above(

dataframe[f'ema_short_{self.buy_ema_short.value}'], dataframe[f'ema_long_{self.buy_ema_long.value}']
|
||||
))
|
||||
|
||||
# Check that volume is not 0
|
||||
conditions.append(dataframe['volume'] > 0)
|
||||
|
||||
if conditions:
|
||||

|
||||
```
|
||||
|
||||
Breaking it down:
|
||||
|
||||
Using `self.buy_ema_short.range` will return a range object containing all entries between the Parameters low and high value.
|
||||
In this case (`IntParameter(3, 50, default=5)`), the loop would run for all numbers between 3 and 50 (`[3, 4, 5, ... 49, 50]`).
|
||||
By using this in a loop, hyperopt will generate 48 new columns (`['buy_ema_3', 'buy_ema_4', ... , 'buy_ema_50']`).
|
||||
|
||||
Hyperopt itself will then use the selected value to create the buy and sell signals
|
||||
|
||||
While this strategy is most likely too simple to provide consistent profit, it should serve as an example how optimize indicator parameters.
|
||||
|
||||
!!! Note
|
||||
`self.buy_ema_short.range` will act differently between hyperopt and other modes. For hyperopt, the above example may generate 48 new columns, however for all other modes (backtesting, dry/live), it will only generate the column for the selected value. You should therefore avoid using the resulting column with explicit values (values other than `self.buy_ema_short.value`).
|
||||
|
||||
??? Hint "Performance tip"
|
||||
By doing the calculation of all possible indicators in `populate_indicators()`, the calculation of the indicator happens only once for every parameter.
|
||||
While this may slow down the hyperopt startup speed, the overall performance will increase as the Hyperopt execution itself may pick the same value for multiple epochs (changing other values).
|
||||
You should however try to use space ranges as small as possible. Every new column will require more memory, and every possibility hyperopt can try will increase the search space.
|
||||
|
||||
## Loss-functions
|
||||
|
||||
Each hyperparameter tuning requires a target. This is usually defined as a loss function (sometimes also called objective function), which should decrease for more desirable results, and increase for bad results.

|

You can also enable position stacking in the configuration file by explicitly setting
|
||||
`"position_stacking"=true`.
|
||||
|
||||
## Out of Memory errors
|
||||
|
||||
As hyperopt consumes a lot of memory (the complete data needs to be in memory once per parallel backtesting process), it's likely that you run into "out of memory" errors.
|
||||
To combat these, you have multiple options:
|
||||
|
||||
* reduce the amount of pairs
|
||||
* reduce the timerange used (`--timerange <timerange>`)
|
||||
* reduce the number of parallel processes (`-j <n>`)
|
||||
* Increase the memory of your machine
|
||||
|
||||
## Show details of Hyperopt results
|
||||
|
||||
After you run Hyperopt for the desired amount of epochs, you can later list all results for analysis, select only best or profitable once, and show the details for any of the epochs previously evaluated. This can be done with the `hyperopt-list` and `hyperopt-show` sub-commands. The usage of these sub-commands is described in the [Utils](utils.md#list-hyperopt-results) chapter.
