Tradour explained
A look back checks results already known. A fair live test records the idea before the result exists, so hindsight cannot rewrite it.

Watching an old match again can teach a great deal, but only a prediction sealed before a new match proves what was genuinely expected beforehand.
Now put that into markets
Tradour keeps looking back and testing forward as different record types. Looking back can form ideas; testing forward checks fixed versions.
Prospective records preserve inputs, timestamps, expectations and later outcomes through append-only events. Historical replays remain labelled even when methodologically careful.
Check when the idea was recorded, what data was known and which result was used. Do not let later results rewrite the original record.
Prospective evidence can still be small, noisy or poorly designed. Historical evidence remains useful without being relabelled as live validation.
