VERIFICATION LEDGER

What we back-tested, and what actually survived

Most sites publish only the strategies they want you to trade. This is the full ledger: every systematic study we ran, scored on the same axis, failures included. Publishing the failures is the point — a method that survives 25 pre-registered tests is worth more than one that was never tested.

0.50 means no better than chance. Only values above 0.50 carry information.

How these were judged

Gates are registered before the test runs, so a result cannot be reinterpreted after the fact. Out-of-sample is scored only after the direction has been fixed on in-sample data. Deflated Sharpe discounts the number of variants tried, which is what makes most published back-tests unreliable. Reversing a sign after seeing the result counts as a failure, not a discovery.

Research records, not investment advice. Past back-test or live results do not predict future returns. Trading foreign exchange carries risk of loss.
