The script to run is src/update_prices.py. A virtual environment is recommended to install the dependencies.

Installation

It is recommended to install the setup into a virtual environment. Create one and activate it with the following command (or just ignore these an execute without venv):

    python3 -m venv venv
    source venv/bin/activate

Note: THe second venv is just the path in which the virtual env will be located. Change it at will.

The environment can be deactivated as follows:

    deactivate

Clone the repository in a given location and install its requirementes with the following command, executed from the root folder of the repository. You can check the requirements file to check the libraries that will be installed into your system.

    pip3 install -r requirements

Execution

It is better to configure the script in crontab. To edit the crontab file use in a terminal the command crontab -e. Open the file with the desired editor and add the command to execute. In the following example the command is executed twice a day (at 11 and at 23h). The output ot the command is stored in a log file just in case something needs to be checked later.
