The Trading Fly, a paper trader with receipts
Credibility concern recorded. The source reference remains available for verification and correction.
An interactive experiment follows a fly-brain trader through strategy runs, paper-market decisions, account equity, and replayable receipts.
Field notes
The experiment separates a recorded paper-trading run from a section labeled “Live account,” with strategy runs presented as separate accounts and timelines. Its public interface includes a round-based replay, an example snapshot identified as round 12, and receipt-oriented decision records. Moment cards are rendered in the browser from pinned data and the original character sheet, with export formats for square, portrait, and vertical layouts. The page also says no result is invented and distinguishes decisions from fills.
