What is Whalefax?
Whalefax focuses on how a performance number is built. It matches fills, handles cents-versus-dollars input, includes settled losing positions and exposes the reconstructed result through charts and tables. CSV processing is described as local to the browser; public wallet lookup and the whale leaderboard are separate paths.

What to check
- FIFO is a reconstruction method; it may differ from another platform’s display or the method used in your accounts.
- Missing fills or transfers can change reconstructed cost basis.
- An accounting-shaped export still requires review of its underlying rows.
- A leaderboard is not the same dataset as a personal CSV import.
