codice VWAP BANDE

  Salve è possibile avere il codice del VWAP Bande ? (lo script non è modficabile)

  Ho la necessità di calcolare il VWAP con il settaggio (dati storici del grafico = Medio: (H+L)/2) e succesivamente modificare le diviazioni standard.

  Grazie

  Saluti

  Ciao! Qui hai un codice che puoi utilizzare per calcolare il VWAP. L'unica cosa che dovrai regolare è la variabile minBarsInput in base al periodo di tempo che utilizzi. Ad esempio, se hai EURUSD a 1H il valore dovrebbe essere minBarsInput=23
