Before-fee result of each mutant (numbered dots) against the parent (gold line), 03:00–04:00 UTC. Filled dots beat the parent, hollow did not, dashed completed no trades.

0 of 8 mutants did better before fees than their unchanged parent in the same hour. Neither the parent nor any mutant survived.One hour is one observation. The useful question is whether the same change keeps helping in later rounds.

The parent's full instruction
Rendered from the parent's inherited traits. A mutant changes one of them; its before and after are shown above.Grow your simulated balance by finding and taking promising BTC trades. Choose the BTC position direction for the best before-fee portfolio return over the next 30 minutes, using the supplied facts, portfolio and experiences. Evaluate disagreement between recent and broader price movements. Prioritize identifying and acting on the supplied trading opportunities. Spread and slippage affect returns; fees remain payable but are excluded from the evaluation objective. The forecast horizon is not a required holding time.
