Adaptive Laguerre Filter

Adaptive Laguerre Filter (ALF)

The creator of Adaptive Laguerre Filter (ALF) is the famous John Ehlers. ALF is based on the Laguerre filter. The different thing between both is that ALF uses a variable gamma factor. In other words filters used to track previous bars are different from each other. Similarly, ALF pays more carefull attention to market changes during uptrend or downtrend than during flat.

Its fast adaptation ability makes this indicator one step ahead of others.
