"""EUR/USD signal producer config.

Re-tuned 2026-07-10 against the realistic backtester (1-pip round-trip
cost, next-open fills, raw-path resolution) on 2025-07-08 → 2026-07-08
M5 with M15/H1 confirmations. RESULT: no configuration passed the
acceptance rule (positive in BOTH train and val halves, PF >= 1.3).

The M5 defaults below are the best found — roughly breakeven
(-1.1R / 53 trades / PF 0.93 / 62% WR on 12mo) versus the donor
branch's -6.7R. Findings that shaped them:
  - transitioning regime bled -27R/88 trades wide-open → blocked
  - A-grade entries LOSE (-26R) while B-grade wins — max conviction
    fires at move extremes (same pathology as gold M5)
  - Fridays (-17R) and hours 8, 12, 13, 18, 19 UTC negative
  - score 30-35 band is where the train-half losses live → floor 35
  - trailing exits beat static TP1 (arm 0.45R / dist 0.5R best)

M15 + H1 investigated 2026-07-11, verdict NO VALIDATED EDGE either
(all at 1-pip round-trip cost, real fills):
  - M15 wide-open (all gates off): -2.5R/270 trades 2025-26;
    -54.8R/308 trades on 2024-25 out-of-sample. PF 0.61-0.98.
  - Best in-sample slice (transitioning-regime-only: +15.4R, PF 1.59,
    positive both halves, month-spread) FAILED 2024-25 OOS at PF 0.55.
    Within-year train/val splits are not sufficient for EUR — always
    re-test on the 2024 window before believing a config.
  - Raw-parquet forward-return screens (M15 and M5, ~14 entry
    conditions x 4-5 horizons: momentum, mean-reversion, breakout,
    streak, session families): nothing clears +1 pip in both years.
  - H1 wide-open: +9.8R PF 1.32 in 2025-26 (both halves positive) but
    -5.7R PF 0.82 on 2024-25. Positive from Jan 2025 onward; H2-2024
    regime negative. Closest to workable, still unvalidated.

Root cause is cost-to-volatility: EUR M15 ATR ~= 10 pips, so the 1-pip
spread taxes every trade ~10% of ATR (M5 worse). The XAU signal engine
survives because gold's ATR/spread ratio is several times larger.

EUR/USD therefore ships FUNCTIONAL BUT OFF by default: it is not in
PlatformConfig.scan_pairs. Scan it on demand (main.py --pair EURUSD,
or add to scan_pairs) but treat all EUR M5/M15 signals as informational
only. Open avenues needing new data/infra: calendar-anchored entries
(requires a historical Forex Factory archive), limit-entry cost
reduction (needs tick data to model fills honestly), H4/D1 swing.
