Aparte de las dificultades para codificar el indicador :), creo que se vuelve a pintar porque la cuadrícula se calcula con el máximo y mínimo de todos los tiempos y se adapta en tiempo real, para que siempre obtenga una precisión perfecta del pasado. ¿Ya lo has usado con éxito? (y en tiempo real?).

La verdad que no lo he probado ni testeado este indicador…..pero si finalmente repinta no es interesante la traducción.Gracias y disculpe las molestias.
