📅 Day-of-Week Performance
Brain accuracy stratified by weekday · the brain grows positions during strong days, shrinks during weak ones
📊 Per-day accuracy
📚 Why day-of-week matters
  • Monday — Weekend news gap, often gappy open, late-day positioning
  • Tuesday — Earnings season heavyweights, FOMC meetings often start
  • Wednesday — FOMC decisions, mid-week pivot, lower volatility usually
  • Thursday — Earnings continue, jobless claims, NFP eve setup
  • Friday — Monthly OPEX (3rd Friday), positioning for weekend, often risk-off
Mechanism: same as HourlyPerf but on a weekly cycle. The UnifiedPredictor compounds this multiplier with hourly perf, dropout, agreement, OOD, bootstrap divergence, and drawdown protection.

What to look for: if your model has a strong edge midweek but loses on Fridays, this gives Brandon a concrete signal to skip Friday trades (or downsize them).
