DAX currently reads bearish, with regime and model leadership broadly aligned.

Win rate is the most intuitive trading statistic and the most misleading one in isolation. A model can win the large majority of its trades and still be unprofitable if the losers are bigger than the winners. This article explains why net pips and per-trade expectancy are the figures that actually measure edge, and how to read win rate correctly as one input among several.

In an evolutionary trading system, the fitness function defines what 'good' means. darwintIQ scores models with a multi-factor fitness that combines expectancy, profit factor, and return stability, then adjusts the result with walk-forward and local-robustness multipliers. This article explains why a single-metric objective produces fragile models and how a composite objective steers the search toward structural quality.

EURUSD currently reads constructive bearish, with regime and model leadership broadly aligned.

darwintIQ has extended the evaluation window for live models to 40 hours and carved off the most recent 8 hours as a true out-of-sample holdout. The genetic algorithm optimises fitness on the training portion only, and a separate selection gate rejects any model that fails to stay profitable on the unseen tail. This article explains how the holdout works, why train-only fitness matters, and how to read the new holdout card in the Trader Detail View.
