Dibuja en 1M la barra de 5M

Soy nuevo usuario... y estoy aprendiendo a realizar mis robots... lo siento si existen errores de programacion, para mi me trabajan y bien... se que se pueden optimizar... acepto sugerencias...

Cabe destacar, que no se nada de programacion, pero me he puedo a leer c# y con los ejemplos he realizado ya varios y soy trader de tiempo completo.

Cabe destacar, que las dibuja conforme pasa el tiempo, no se como hacer que las dibuje de un solo paso.
