--- Logica UL: identica a cedlab_Chart_DailyUL1, estesa a tutti i

+-- Logica basata su:
+--   - cedlab_Chart_DailyUL1: stessa formula performance UL, stessi filtri
+--   - cedlab_Chart_UL1: Strike da CertificatesUnderlyings, StartDate = MIN(Prices.Px_date)

 --   Px_date        DATE
 --   Performance    DECIMAL  -- % su strike/nominal

--- Note: cedlab_Chart_UL1 già restituisce tutti i campi metadata
