RedK Dual VADER con barras de energía

Las mejoras visuales que he añadido en VADER-DEB ayudan a dar más información sobre la acción del mercado

exponiendo el gráfico VADER doble / largo por defecto (que usamos como un proxy para el sentimiento) - y se muestra ahora como un área (en lugar de un histograma) - Todavía se puede ocultar el gráfico del sentimiento en la configuración del indicador y
En la versión 3.0, las líneas DER rojas/verdes opcionales están disponibles en la configuración del estudio y están ocultas por defecto.

Así que esto es VADER doble con barras de energía o VADER-DEB para abreviar.

Estos cambios pueden ser considerados por algunos como pequeños, pero en mi opinión, me parecieron más atractivos visualmente y mejores para conducir acción - Esto funciona mejor para mí como una persona visual - así que pensé en compartir con otros que pueden ser como yo... Esta es la razón por la que decidí publicar esto como una versión separada y no como una actualización del indicador existente - para que pueda elegir cuál prefiere usar.

No hay cambios en el cálculo básico dentro del código, como muestra el gráfico anterior, donde comparamos ambas versiones de VADER.

Si está satisfecho con VADER v3.0, no dude en seguir usándolo.

¡ Qué buena suerte!
