This version of the Laguerre filter on price uses dynamic Gamma calculation based on recent ATR, making it more adaptive and versatile to the recent market movement.
The indicator has also a dynamic channel made of self adjusting levels that act as signals filtering.
You have the ability to change the period used for the levels with the “inpPeriod1” setting, if it is set to 0, the period is the same as the one used for the ATR.
You can add or remove the filling color added between the Laguerre curve and the channel with the “ColorFill” setting.

Hello Nicolas, is it possible to stablish a bullish screener for this indicator when the central filter (FILTER) is bigger than the upper filter (FILTER2) ?
I have tried this, but it does not work:
“PRC_ATR adaptiveLaguerreFilter”[14, 0, 1](close)
c1 = (indicator1 > indicator2)
indicator3, indicator4, ignored = CALL “PRC_ATR adaptiveLaguerreFilter”[14, 0, 1](close)
c2 = (indicator3[1] <= indicator4[1])
SCREENER[c1 AND c2] (Variation AS "% Var barra ant")
Please open a topic in the screener section to ask for this specific query.
Hello,
the indicator doesn’t show up anything on the screen, any suggestions please?
