🚀 Installation

If you don't plan on touching the code, simply run (with python >=3.8 and pip installed):

pip install finalynx  # run again with --upgrade to update

And you're done! Now create your own copy of the demo.py example anywhere and run it to make sure everything works. You can now customize it for your own needs 🚀

Pro Tip 💡: Why not setup a script to autorun your config in a new terminal at startup? Could be a nice view 🤭

⚙️ Usage

The goal is to declare a tree structure of your entire portfolio independently from their host envelopes (e.g. PEA, AV, CTO, etc). Once your entire portfolio strategy is defined here, find the best envelope for each line and add them to your Finary account (manual or automatic sync). Finalynx will fetch each line and display your full portfolio with real-time amounts.

Step 1: Portfolio

To create your portfolio, start with a Portfolio object which holds a nested list of Line, Folder, and SharedFolder objects:

• Line represents each individual investment. Set the key parameter as the name shown in your Finary account if different from the display name.
• Folder holds a group of lines or subfolders to create a structure.
• SharedFolder accepts a Bucket object which groups multiple lines as a single object. You can reference the same bucket multiple times in the tree and set different bucket_amount for each shared folder. Each folder will only take the specified amount and let the others below use the rest.

Here is an example of a portfolio structure:

# Create a list of Lines that will be considered as a single Line.
my_bucket = Bucket([
  Line('name_in_finary'),
  Line('My Asset 2', key='name_in_finary'),  # change the display name
  # ...
])

# Define your entire portfolio structure
portfolio = Portfolio('My Portfolio', children=[
  # Add a list of `Line`, `Folder`, and `SharedFolder` objects
  Folder('Short term', children=[
    Line('My Asset 3', key='name_in_finary'),
    SharedFolder('My Folder', bucket=my_bucket, bucket_amount=1000),
    # ...
  ]),
  Folder('Long term', children=[
    # `(Shared)Folders` can be displayed as Expanded (default), Collapsed, or as a Line
    Folder('Stocks', display=FolderDisplay.COLLAPSED, children=[
      SharedFolder('My Folder', bucket=my_bucket),  # display what's left in the bucket
      # ...
    ]),
    # ...
  ])
])

Step 2: Targets

Any node in the tree accepts an optional target parameter. See the full list of available targets here:

Folder('Stocks', target=TargetMin(2000, tolerance=500), children=[
  Line('ETF World', key='Amundi ETF ...', target=TargetRatio(80, tolerance=5)),
  # ... Add other lines with the remaining 20% of the Stocks folder.
])

Step 3: Run the Assistant

Here is the bare minimum code accepted:

from finalynx import Portfolio, Assistant
portfolio = Portfolio()  # your config here
Assistant(portfolio).run()

The Assistant class accepts a few options (which can also be set from the command line, see python your_config.py --help):

Assistant(
    portfolio,
    ignore_orphans=False,  # Ignore fetched lines that you didn't reference in your portfolio.
    force_signin=False,    # Delete your saved credentials and/or cookies session.
    hide_amount=False,     # Hide your portfolio amounts with dots (easier to share).
    hide_root=False,       # Display your portfolio without the root (cosmetic preference).
).run()

There are other small options here and there, let me know if you're interested (I should write a full documentation). However, you should be good to go with some inspiration taken from demo.py.
