Findings derived from the full panel. Each carries its number and its denominator; the computations are reproducible with artifact 8fb75dc6eee1.
Long while the 50-day SMA is above the 200-day SMA; flat when it is below. Next-close execution. No leverage, no stop.
The verdict compares the strategy with buying and holding EUR/USD over the same window, with round-trip costs per asset class. “Out of sample” is walk-forward: the rule is fit on one stretch and judged on the next. A result that beats in the full sample but not out of it is overfit. Full methodology in the protocol. How we test.
