Range filter

Inspired by the QQE’s volatility filter, this filter applies the process directly to price rather than to a smoothed RSI.

This is an experimental study designed to filter out minor price action for a clearer view of trends.

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.

Custom bar colors are included. The color scheme is based on the filtered price trend.

Select the type you want to use via the “Filter Type” input. Type 1 is the original formula.
Multiple range sizing methods are available. You can choose from the following scales:

Points
Pips (Works best with forex pairs, obviously)3
Ticks4
% of Price
ATR
Average Change (Default. This is the original sizing method.)
Standard Deviation

Range smoothing is optional, and you can specify your smoothing length. Smoothing only affects dynamic scales (ATR, Average Change, and Standard Deviation).
Filter movement can be determined using wicks or close. This can be specified via the “Movement Source” input.

This code is compatible only with PRT v11. Use this version with prior version of the platform: https://www.prorealcode.com/prorealtime-indicators/range-filter/#comment-10834

BobFlynn • 10/06/2020 #
Awesome Nicolas !! I’m glad you took the time to work on this. Can’t thank you enough ! 🙂
- BobFlynn • 10/06/2020 #
  Unfortunately, the 10.3 code is missing some parts and cant compile. @IV MCM can you check ? I think the Copy Paste is broken in the comments… Merci d’avance 🙂

IV Mcm • 10/06/2020 #
Indeed, copy-paste does not work.

You must delete “floor” in the original code line 62 and 64.
You must also delete the “bordercolor (x,x,x,x)” line 122-123-124 and 125.

Canis Majoris • 10/06/2020 #
Bonjour Nicolas,

J’ai pas bien compris le principe de fonctionnement de ce range filter indicator ?

quelle est la signification de la bougie grise ? Je vois 3 couleurs de bougies possible ( vert, rose et gris ) !
Merci
- Nicolas • 10/06/2020 #
  La définition des couleurs se situent entre les lignes 94 et 118. Selon le type de bougie (haussière ou baissière), si elle situe dessus/dessous de la ligne centrale (le range filter) et si cette dernière est ascendante ou descendante. Je ne suis pas l’auteur de cet indicateur, j’ai réalisé une conversion de code suite à une demande.

Manu35250 • 10/06/2020 #
Bonjour Nicolas,

Est il possible de convertir cet indicateur en screener ? J’essaie depuis plusieurs jours mais impossible.

Merci de votre retour.
- Nicolas • 10/06/2020 #
  Bien sûr, merci de formuler la demande dans le forum approprié en respectant les règles de publication et je serai en mesure de t’aider.
