_settings module ¶

Global settings.

settings config is also accessible via vectorbt.settings.

Here are the main properties of the settings config:

It's a nested config, that is, a config that consists of multiple sub-configs. one per sub-package (e.g., 'data'), module (e.g., 'array_wrapper'), or even class (e.g., 'configured'). Each sub-config may consist of other sub-configs.
It has frozen keys - you cannot add other sub-configs or remove the existing ones, but you can modify them.
Each sub-config can either inherit the properties of the parent one by using dict or overwrite them by using its own Config. The main reason for defining an own config is to allow adding new keys (e.g., 'plotting.layout').

For example, you can change default width and height of each plot:

>>> import vectorbt as vbt

>>> vbt.settings['plotting']['layout']['width'] = 800
>>> vbt.settings['plotting']['layout']['height'] = 400

The main sub-configs such as for plotting can be also accessed/modified using the dot notation:

>>> vbt.settings.plotting['layout']['width'] = 800

Some sub-configs allow the dot notation too but this depends whether they inherit the rules of the root config.

>>> vbt.settings.data - ok
>>> vbt.settings.data.binance - ok
>>> vbt.settings.data.binance.api_key - error
>>> vbt.settings.data.binance['api_key'] - ok

Since this is only visible when looking at the source code, the advice is to always use the bracket notation.

Note

Any change takes effect immediately. But whether its reflected immediately depends upon the place that accesses the settings. For example, changing 'array_wrapper.freq` has an immediate effect because the value is resolved every time ArrayWrapper.freq is called. On the other hand, changing 'portfolio.fillna_close' has only effect on Portfolio instances created in the future, not the existing ones, because the value is resolved upon the construction. But mostly you can still force-update the default value by replacing the instance using Configured.replace().

All places in vectorbt import settings from settings, not from vectorbt. Overwriting vectorbt.settings only overwrites the reference created for the user. Consider updating the settings config instead of replacing it.

Saving¶

Like any other class subclassing Config, we can save settings to the disk, load it back, and update in-place:

>>> vbt.settings.save('my_settings')
>>> vbt.settings['caching']['enabled'] = False
>>> vbt.settings['caching']['enabled']
False

>>> vbt.settings.load_update('my_settings')  # load() would return a new object!
>>> vbt.settings['caching']['enabled']
True

Bonus: You can do the same with any sub-config inside settings!
