A Period-Based Laguerre Filter with Fractional Settings

Summary

This indicator adapts the Laguerre filter associated with John Ehlers by replacing its less familiar gamma parameter with a calculation period. It is intended to behave more like other moving-average-style indicators, with price and period as the main inputs. The period may be fractional rather than an integer, allowing experimental settings such as 1.5 for a fast filter that the author says can remain smooth.

The text describes the filter as producing smooth output even at short periods and suggests using changes in its color as signals. It gives no formula, parameter mapping between period and gamma, market examples, or backtest evidence. The claimed smoothness and usefulness are therefore qualitative, and the document does not specify how color changes should be traded or how signals should be validated.

Key ideas

• The filter replaces the Laguerre gamma input with a more familiar calculation period.
• The period can be fractional, which the author proposes for experimenting with faster settings.
• Price and calculation period are the stated inputs.
• The author suggests using color changes as signals but gives no testing evidence or trade rules.
