fin

fin is a Trading212 CSV utility that aggregates your transaction CSV files into a couple of output formats.

You can generate an aggregate formatted JSON file that's used by the reporting tool, or you can generate a yahoo formatted CSV file that can be imported into Yahoo Finance.

The tool deals with pies, stock splits and Yahoo ticker symbols. However, it's required by the user to maintain these settings in the config.yaml file. After running the tool for the first time a default config.yaml file will be generated for you.

Note

The goal of this tool is to give a big overview of your portfolio, along with fees and costs. It combines all transactions and comes up with a final tally, as such it's not meant to help with taxes. This also means that for the Yahoo format we don't show all lots, again, just the final tally.

Beware

Trading212 is under no obligation to keep their CSV format the same. History has proven that they do change things from time to time, which either invalidates old CSVs or won't work with new.

We suggest to download new CSVs if you're experiencing problems. This can be done in 1-year increments.

Usage

$ aggregator --help
Usage of aggregator.:
  -config string
        YAML file with configuration for this run
  -pie-only string
        Only output specific pie output
  -skip-pies
        Skip pie separation during output

Most of the settings are actually configured in config.yaml. The flags allow you to override some specific settings.

Reporting

The project has a reporting tool that can be used to generate a report of your portfolio. It's also available at https://fin.gerben.dev as hosted by GitHub Pages.

It uses jQuery, Bootstrap and Bootstrap Table to generate the report. It has a local file mode using LocalStorage, with the resources coming from a CDN. This means you can just open the report/index.html file in your browser and it will work.

Remember to run the aggregator tool first to create your aggregated_quotes.json file. You can also use the agg.json example output file in this repo to test the reporting tool.

The default currency is set to EUR, but you can use the dropdown to change it to GBP or USD.
