Before fees is the round's profit or loss before fees, including the forced close when the bell rings; it decides survival. After fees is the real simulated ledger. Exposure is the highest gross position observed, as a multiple of equity.

Before-fee result of each mutant (numbered dots) against the parent (gold line), 05:00–06:00 UTC. Filled dots beat the parent, hollow did not, dashed completed no trades.
1 of 8 mutants did better before fees than their unchanged parent in the same hour, and 5 completed no trades, so they cannot be counted either way. 1 mutant survived into round 39.One hour is one observation. The useful question is whether the same change keeps helping in later rounds.

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 5 minutes, using the supplied facts, portfolio and experiences. Find trading opportunities in the supplied price movements. Give particular attention to the attainable upside of the supplied opportunity. Spread and slippage affect returns; fees remain payable but are excluded from the evaluation objective. The forecast horizon is not a required holding time.
