Laguerre Filter Metatrader 5 Forex Indicator

John Ehlers explained the Laguerre filter long time ago in the “Time Warp – without Space Travel” document.

The “gamma” parameter is the reason why the Laguerre filter is not widely used because traders do not extensively grasp what it does.

This version eliminates the Gamma parameter and only uses the period, a parameter that the majority of traders are used to deal with.

The MT5 Laguerre filter indicator without the gamma component produces very smooth results even when deployed for very short periods.

It’s ok to use it for scalping, day trading and swing trading purposes.
