trade-journal
This project contains a library and an executable for managing and tracking trades placed with a broker (buy and sells of different instruments), and other events that may occur as a result of having an account with that broker (interest, dividends, etc).
Currently, the code is organized around a multi-stage flow of data from the broker:
-
Get raw CSV import from the broker.
-
Convert CSV data into a stream of Entry values. There should be a test for every possible variation of CSV datum.
-
Calculate the Open and Close disposition of buys and sells implied by that stream of Entry values.
-
Calculate the profit and loss implied by those Open and Close events.
-
Adjust this profit and loss by applying any tax-related laws. This may not apply for every country, and may apply differently based on the instrument itself.
