What is the Range Filter?
As the author of the original Range Filter describes it:
“This is an experimental study designed to filter out minor price action for a clearer view of trends. Inspired by the QQE’s volatility filter, this filter applies the process directly to price rather than to a smoothed RSI .
First, a smooth average price range is calculated for the basis of the filter and multiplied by a specified amount.
Next, the filter is calculated by gating price movements that do not exceed the specified range.
Lastly the target ranges are plotted to display the prices that will trigger filter movement.

Bonjour, une petite demande concernant cet indicateur : comment faire pour que lorsque la bougie entre dans une zone verte ou rouge, cette zone change de couleur par exemple en rouge foncé ou en bleu (à la place du vert initial) ?
merci.
Bonne journée.
Bonjour, la coloration des bandes se fait ligne 111 et 112 à l’aide des instructions colorbetween. Il suffit de mettre ces deux instructions entre des conditions (IF THEN ELSE END) en fonction de ce que l’on veut exactement et de changer les couleurs appliquée en fonction des conditions, sachant que la ligne du milieu est filt, le haut hband, le bas lband. Tu peux ne changer que la transparence en fonctions des conditions désirée (ici elle st à 30). Voir : https://www.prorealcode.com/documentation/colorbetween/
