Notes
The method changes the answer, often by more than anything else in a return. Run it three times and compare.
Wash sales are not modelled, and this is arithmetic rather than tax advice.
Workspace controls
Save a full workspace when you want the tool state, files, and team note preserved together.
Versions and sharing
Output versions appear here after successful runs so users can compare before exporting again.

Good to knowEvery other tool that does this wants your whole trade history on their server. This one reads the CSV in your browser and writes the answer back out, so the file that lists everything you own never moves.
