I AM TRYING TO WRITE SOME CODE TO FIND STOCKS WITH A LARGE, FAIRLY EVEN, SINUSOIDAL DIVERGENCE PATTERN. PRESENTLY WORKING WITH CSTDDEV, BUT NO PROGRESS. ANY IDEAS WOULD BE GREATLY APPRECIATED.
THANX,

The Fisher Transformation starts from the analysis of a sine wave.

It would be helpful to define exactly what type of divergence you are looking for - I'm assuming it is "the MACD keep going lower while the price rises" sort of thing?
This is easier to filter for as an individual event rather than as a periodic event. For the latter you also would need to define the periodicity of the sinusoidal component as well as what constitutes a "divergence" (how big a difference in percent, for example).

FOUR, THANX FOR THE REPLY, LOOKED UP FISHER TRANSFORM ON WIKIPEDIA, FELT LIKE A MONKEY STARING AT A WRIST WATCH (OR MAYBE AN APPLE WATCH).
THINKING AS I WRITE, I ENVISION A SINE WAVE (OR 1/2 SINE WAVE) WITH A PERIOD EQUAL TO THE NUMBER OF DAYS BETWEEN THE TWO POINTS THE MACD VARIANCE IS ZERO. THE AMPLITUDE COULD BE ONE, OR SOME DERIVATION
OF THE VARIANCE AMPLITUDE BETWEEN THE TWO "ZERO" POINTS. THEN DESIGN A FILTER TO MEASURE THE "FIT" OF THE DATA TO THE IDEAL (THE SINE WAVE). I GUESS THE AVERAGE DEVIATION OF EACH DAYS MACD VARIATION TO THE SINE WAVE MIGHT BE A PLACE TO START.
DOES ANY OF THIS MAKE ANY SENSE?

Seems like you might like to investigate John F. Ehlers.

I'll say one thing that IFT(5,9) holding above or below certain levels is very interesting when following up or down trends
Some examples

FOUR,
EHLERS METHODOLOGY IS WHAT I WAS TRYING TO DESCRIBE. HIS BOOKS ARE EXPENSIVE, AND I DON'T KNOW IF I COULD UNDERSTAND THEM AFTER I BOUGHT THEM. I WILL SEE WHAT I CAN LEARN WHILE "PECKING AROUND THE EDGES'.
