semplice alert...

New comment
 

Buongiorno a tutti

vorrei sapere se qualcuno può scrivermi un semplice alert basato su una linea retta ...mi spiego vorrei che una volta messa la linea orizzontale mi suonasse un alert quando il prezzo attraversa e chiude sotto o sopra di questa a secondo della modalita che si sceglie

Good morning everyone


I would like to know if someone can write me a simple alert based on a straight line ... let me explain I would like that once the horizontal line has been placed, an alert will sound when the price crosses and closes below or above it depending on the method chosen
