Explore projectPrice-only market simulator · not a predictor

What began as an intentionally “dumb” price-only prediction experiment became a more honest tool: a simulator for studying market structure, co-movement, and extreme scenarios without claiming to forecast the next move.

Explore projectStopped experiment · incentives over cleverness

Baseball Scraper

A ticket-market investigation that looked technically clever but failed the more important test: it would still reward fraud, while resale fees erased the apparent spread.
