Market Price Prediction

The Market Price Prediction page is the main forecast view, organized into two tabs: Day Ahead and 7 Days.

Tabs

Day Ahead

Focused view of D+1 (and D+2 after 10:00 CET) price forecasts:

  • ForecastStatusBar — OMIE D+1 publication status and D+1 Forecast update time with countdown. Strategic card is hidden on this tab.
  • SevenDayChart (reused with title="Day-Ahead Forecast") — D+1 only with MAE-based confidence bands. Date range adapts: data-driven start through tomorrow (after 10am CET) or today (before 10am CET).
  • Approach filter: hybrid15 / pure15 / expanded.

7 Days

Full 7-day forecast horizon merging D+1 and D+2–D+7 strategic forecasts:

  • ForecastStatusBar — Full three-indicator status bar showing OMIE D+1 publication, D+1 Forecast update, and Strategic D+2–D+7 update times.
  • SevenDayChart — Dual-product chart merging dayahead and strategic forecasts into a single 7-day 15-minute view. MAE-based confidence bands: inner ±½ MAE, outer ±1× MAE. D+1 uses dayahead-specific MAE; D+2–D+7 uses strategic-specific MAE.
  • Price Heatmap — 7-day hourly price grid combining actuals and forecasts. 15-minute data is averaged to hourly buckets. Color-coded by price level (green → yellow → red), marks the 3 cheapest hours per day, shows daily aggregates, and supports CSV export.
  • Approach filter: hybrid15 / pure15 / expanded.

Controls

Approach Filter

Switch between hybrid15 (recommended — combines 3+ years expanded history with genuine 15-min data), pure15 (genuine 15-min data only), and expanded (hourly replicated to 15-min). All tabs use 15-minute resolution.

Run Mode

When viewing forecast data, the dashboard automatically shows the most relevant product based on time of day — D+1 day-ahead before OMIE publication, strategic afterward.
