Script Strategies¶

This release also introduces a simplified version of the trading strategies called Script. The scripts are intended to be used without requiring a configuration. All data used by the script should be included in the script file.

The script is a Python class. It can be created by subclassing the new ScriptStrategyBase class. All scripts modules should be stored in the /scripts folder (the old scripts folder is renamed to pmm_scripts). There is a new version of the start command for the scripts: start --script <script_module_name>
