Why isn't it updating the data? In order to calculate Support and Resistance (D2 and D4) my sheet uses C2 and C4 (today's H & L) and I thought I told my vb code that if it saw any changes in those two cells within the time C3 (US market open, CET), it would have to change D2 and D4, automatically. Well, it does so, but only if I paste different values on C2 and C4 - not if such values get changed by the source live data (from Interactive Brokers). How do I make the sheet react to the data changing other than by pasting it each time on the cell? I am attaching the file in my next message.
