Most indicators out there run on bars. Let’s take a 3-period moving average. You compute it on the Close, the previous Close, and the Close before that. Well, what if you used 3 other values in your average, instead of the last three prices? Like, what if you used the current value of the 2-EMA, 5-EMA, and 8-EMA and computed the average of those instead?

Ehlers uses the 4-RSI as an example application of the Laguerre treatment. Instead of the last 4 Closes, he uses 4 Laguerre values. Using only four values makes the indicator turn quickly, but you can adjust the overall speed of the output via the gamma input to the transform. Pretty neat!

In July, I looked around briefly to see what other Laguerre indicators were out there. Surprisingly, I couldn’t find any. I thought that was strange, because all you have to do is plug in the Laguerre values you need and see what happens. I coded up a few, and found the the Ergodic Candle Oscillator looked pretty good Laguerre-ized.
