@Tromador - Sorry for the delay in getting back to you with the python installation instructions for the Mac, I got side tracked by TD Helper. The instructions are very simple as follows:
*****
Mac OS and Python
As of 10.9, OS X ships with Python 2.7.6. DO NOT "upgrade" your system to the latest version (3.7 at the time of writing) instead download the latest python installer for MacOs from https://www.python.org/downloads/. Once it has downloaded run the installer by locating the downloded file in the Filer and double-clicking the .pkg file or right-click on the file and choose 'Open'
Click on the 'Continue' button and the 'Agree' button where necessary until the last screen is reached where you press the 'Install' button and python will be installed. You will be asked to enter your admin password once the installation has started.
Checking it works
Open a terminal window and cd to the directory that contains the "trade.py" file from the source. Once you've found it, verify that it works by typing:
Code:
$ python3.7 trade.py help
It should respond with basic usage instructions.
If you have installed a different verison simply change the 3.7 to the version that you just installed.
Proceed to the "Getting Started" section below

I do have some screen shots if you need them. Send me a PM with an email and I'll bung them over.
