Pure Python

Note:

This is a work in progress. It's a software configuration guide. This Is Not Financial Advice.

Pre requisites

The pure-python install assumes that you are working on a linux machine running Debian 12 (bookworm) or similar Raspberry Pi OS using Python 3.11

System libraries

Most Debian had already installed Python3 and its basics components, but you may want to run this apt installs as root or sudo:

apt update
apt install -y python3 build-essential git libssl-dev gcc python3.11-venv wget cron

Dedicated user

It's recommended to create a dedicated user. This guide also assumes that. 

useradd elena2 --user-group --create-home --shell /bin/bash

Modules installation

Logged as the dedicated user, install the modules on a new virtual environment.

The modules are:

  • elena: main trading lib.
  • elena-basics: basic strategies ready to use.
  • elena-notifications-telegram: plugin to send notifications to telegram.
python3 -m venv elena2_venv
source elena2_venv/bin/activate
pip install -U pip setuptools wheel
pip install git+https://github.com/Pasta-fantasia/elena.git@v2.4.1
pip install git+https://github.com/Pasta-fantasia/elena-basics.git@v0.1.7
pip install git+https://github.com/Pasta-fantasia/elena-notifications-telegram.git@v0.0.1

Note: if you have a previous version is recommended to uninstall elena and elena-basics before upgrading.

Create a data directory

mkdir $HOME/local_data

Create basic configuration files

cd $HOME/local_data
wget https://raw.githubusercontent.com/Pasta-fantasia/elena-docs/main/docs/assets/configs_2.3.2/config.yaml
wget https://raw.githubusercontent.com/Pasta-fantasia/elena-docs/main/docs/assets/configs_2.3.2/secrets.yaml
wget https://raw.githubusercontent.com/Pasta-fantasia/elena-docs/main/docs/assets/configs_2.3.2/strategies.yaml

Test

cd
elena
You should see something like:

Configure bash environment

echo "source $HOME/elena2_venv/bin/activate" >> $HOME/.bashrc
echo "export ELENA_HOME=$HOME/local_data" >> $HOME/.bashrc
source $HOME/.bashrc

Configure cron

Download the cron shell script: 

wget https://raw.githubusercontent.com/Pasta-fantasia/elena-docs/main/docs/assets/configs_2.3.2/cron.sh

Check that cron.sh is pointing to your Python virtual environment and ELENA_HOME by running bash cron.sh, you should find last.log file on $HOME with the same contents of the image above.

Add this line using crontab -e: 

* * * * * BASH_ENV=~/.bashrc bash -c -l "bash cron.sh"

Wait for a minute, and you should find last.log file on $HOME with the same contents of the image above.

Congratulations!

Now you have the basic Elena installed. The next step is to configure the exchanges, telegram (optional) and your strategies.
