Hi guys! I’m coming crazy with this… Please, look at the image below (attached) and tell me WHY May 11th is missed with this simple code: if intradaybarindex = 0 then maximo = undefined minimo = undefined endif IF time = 075900 then maximo = dhigh(0) minimo = dlow(0) endif return maximo coloured (255,0,0) as "Máximo", minimo coloured (0,255,0) as "Mínimo" Any help will be much appreciated, thank in advance!
