What is Laguerre RSI?

Laguerre RSI applies Laguerre smoothing to an RSI-style calculation and displays the result as a single line in a separate MT4 pane. The smoothing creates a rounded visual path for comparing recent movement.
The package includes an .ex4 file. The line can be reviewed with the displayed scale and with the price structure on the main chart.
How to use Laguerre RSI

Compare the smoothed line with the upper and lower reference areas and the corresponding price chart. Changes in slope and distance from those areas describe the displayed oscillator state.
gamma controls the Laguerre smoothing factor. The default is 0.7; the display can be reviewed together with other chart context.
Where it helps
Laguerre filtering produces a rounded line for chart comparison.
One main line and its scale make the display easy to scan.
