installer.sh

#!/bin/bash

# === Description ======================================================================================================
#
# This file contains the installation procedure to get up and running with Freqtrade and the MoniGoMani HyperStrategy.
#
# === Requirements =====================================================================================================
#
#  - UNIX Distro, macOS, or a POSIX compliant WSL Distro (sh, bash, command, mktemp, pwd, rm, /dev/null)
#  - Python 3.8+
#  - Git
#  - Pip3 python package manager
#
# Windows Specific Notes:
#   This script has been made with the intention to run on UNIX systems and it makes use of UNIX command line tools..
#   However if you really have no other option, it should also be able to run under WSL (Windows Subsystem for Linux)!
#   - See for installation:       https://docs.microsoft.com/en-us/windows/wsl/install-win10
#   - Then change 'sh' to 'bash': https://unix.stackexchange.com/a/442517
#
# === Usage ============================================================================================================
#
#   /usr/bin/env sh <(curl -s "https://raw.githubusercontent.com/Rikj000/MoniGoMani/development/installer.sh")
#
# === Settings =========================================================================================================
INSTALL_FOLDER_NAME="freqtrade-mgm" # By default the folder will be created under the current working directory
MGM_REPO_URL="https://github.com/Rikj000/MoniGoMani.git"
MGM_BRANCH="development"
MGM_COMMIT=""
# ======================================================================================================================
