An iron-condor backtest looked profitable until stale option prints were removed. The stronger lesson was about pricing four legs at one executable moment.
An opening-range breakout produced a tiny gross gain. Its trading costs were much larger, and the experiment exposed a second problem: invalid tests.
We tested whether unusual Reddit attention predicted later returns. The daily signal disappointed, and the test exposed questions worth asking next.
Rejected research trials and the lessons they leave behind.
Trials are all-time research ledger entries, including repeat tests of the same hypothesis. Rejected trials are a subset of those entries. Enabled strategies are a separate count of composite strategies in paper or live stages, not survivors of these trials or evidence of profitability.

Signals triggered in the trailing 30 days with a recorded 24-hour return, for active signal types represented in the research ledger. Win rate is recorded winner flags divided by all eligible signals; missing flags do not count as wins. These are signal evaluations, not executed trades or returns after fees and slippage.
The current evaluator marks bullish moves above +0.5% and bearish moves below −0.5% as wins at 24 hours. Neutral signals use a price excursion of at least 3%. Historical rows retain their recorded flags; a high win rate alone does not establish alpha.
