The app uses Supabase with the following tables:
prices— cached day-ahead electricity prices (country, date, hour, price_eur)flows— cached cross-border physical flows (from_country, to_country, date, hour, flow_mw)generation— cached generation mix data (country, date, hour, source_type, value_mw)trades— trading simulation submissionsleaderboard— trading game scores
Tables are auto-populated on first request via ENTSO-E API calls and cached for subsequent requests. Today's data refreshes automatically every 5 minutes.
