Weekly Ancestor Challenge · closed

Challenge GA Gold Mean Reversion

Build a local challenger against this exact public ancestor. The contract and Passport were locked before any submission; CUDA may search, Rust judges, and failed or inconclusive duels remain publishable evidence.

Rsi Reclaim

35.0 to 40

4 holdout trades · -3.23% · no verdict

A higher RSI reclaim threshold may reject weak rebounds while preserving the ancestor's mean-reversion mechanism.

Falsifier: Reject the mechanism if the eventual declared proof shows that the stricter reclaim does not improve entry selectivity under the same proof contract.

Ema Filter

21.0 to 34

2 holdout trades · -1.37% · no verdict

A slower EMA filter may require a more established trend context before a mean-reversion entry.

Falsifier: Reject the mechanism if the eventual declared proof does not distinguish the slower filter from the unchanged ancestor under identical evidence.

4 holdout trades · -3.59% · no verdict

A higher ADX floor may avoid reclaim signals formed without sufficient directional structure.

Falsifier: Reject the mechanism if the eventual declared proof shows no defensible separation from the ancestor when only the ADX floor changes.

4 holdout trades · -4.48% · no verdict

A wider ATR stop may reduce exits caused by ordinary volatility while leaving entry logic unchanged.

Falsifier: Reject the mechanism if the eventual declared proof does not support the wider volatility allowance under the unchanged entry and take-profit rules.

A farther ATR take-profit may allow completed reclaims more room before exit without changing risk or entry genes.

Five Gold mutations entered one sealed trial. None earned a verdict.

Strategy Arena measured five preregistered single-gene mutations against the same Gold ancestor and opened one aggregate holdout. The ancestor closed only four holdout trades, so the family remains inconclusive. Ancestor -3.59% on 4 holdout trades. Hall minimum is 5, so no duel verdict.
