Añadir alerta a indicador Trading View
Publicado: 22 Mar 2022 15:45
Hola, soy nuevo en el foro. Lo primero mandar saludos a todos y dar las gracias por adelantado a aquellos que atiendan mi consulta. Soy usuario principiante de Trading View, poco a poco estoy aprendiendo sobre Pine pero me cuesta mucho ya que no tengo formación sobre programación. Actualmente uso un indicador al que me gustaría poder añadirle una alerta para no estar pendiente del PC o teléfono, pero no sé como podría hacerlo.
Pongo aquí el código del indicador a ver si me podéis ayudar. Me he intentado documentar pero como no tengo base me estoy volviendo loco y no soy capaz. Muchas gracias.
