The monthly robustness challenge
Anyone can post a pretty equity curve. This board ranks what survives: every strategy published to the marketplace this month is re-scored daily by our engine — same two-year window, same $10,000, same robustness scorecard. No screenshots, no self-reported numbers.
Publish a strategy to the marketplace any time this month. Publishing is the entry — nothing else to fill in.
The engine replays every entry on the identical fixed window and scores it for robustness (deflated Sharpe + random-walk test). Scores refresh daily; at least 5 closed trades required to rank.
Highest robustness score when the month closes wins one month of Pro, applied to the winner's account by the team within a few days.
Think your strategy survives?
Build it in the studio, publish it to the marketplace, and the board picks it up on the next daily scoring run.
This month's board
No scored entries yet this month — publish a strategy and be first on the board.
Entries need at least 5 closed trades on the scoring window to rank. Scoring uses the same public what-if pipeline as the free backtester — every score links to its full report.
Scores describe simulated performance on the stated past window and are not predictions or financial advice. The prize is a service credit (one Pro month); no cash equivalents. Past performance does not guarantee future results.
