How can I translate elliot wave conditions to Python code.

how can i locate AND label local minima and maxima in a dataset?

like when i have the following set as an example of floats like:

400.510009765625, 423.8999938964844, 420.9800109863281, 438.0899963378906, 429.95001220703125, 421.260009765625, 410.3599853515625, 417.1300048828125, 411.760009765625,

and then i compare each adjacent value to the previous by this simple loop:

for x in range(0,len(nfy)): 
    if nfy[x]<nfy[x+1]: 
        print('raising')
    elif="" nfy[x]="">nfy[x+1]:
        print('falling')

i will get a ongoing list of prints of that comparison like:

raising
falling
raising
falling
falling
falling
raising
falling
falling
falling
raising

and so on.

Now my question is: how can i remember, or label, if there is a local minima or a local maxima, compared or related to the surrounding values?

I need to be abble to apply these simple rules here:


The local minima of a falling value (the latest price in a single or a series of "falling" values), after (a series or single) raising values never retraces more than the initial startpoint (which has to be smaller than the next values: it has to be rising).
The turning point from rising to falling values needs to be labeled as "number 1" and is represented by a local maxima.
The turning point from the first falling values to the next rising values needs to be labeled as "number 2" and is a local minima.

When this conditions are met, there has to be a series of raising values which need to exceed the first "local maxima" which has been labeled as "number 1".

The next shift from rising to falling values need to be lebeled as "number 3" and would represent a local maxima.

I want to add in the additionall condition, that "number 3" needs to be higher than "number 1" AND also needs have the largest extend (range), which would be represented by: "number 1" - "startingpoint" < "number 3" - "number 2" (which means the total lenght of the impulse from the starting point to the first maxima needs to be smaller than the total lenght from the first local minima to the seond local maxima.

Then, if these conditions are met, i want to add in the condition, that the next local minima (after local maxima "number 3") is valid, when there is a change from falling values after "number 3" has been labeled to rising values again, which would be labeled as "number 4" and would be represented by a local minima.
Additionally i like to add in the condition, that "number 4" cannot be equal or smaller than the value of "number 1".

**How the hell do i set up this loops?**
How can i translate that into working code?

this is, by the way, a very complicated extraction of the Rules that are based on Elliott Wave Theory. I want to apply this on Stockcharts to count waves.


Best wishes and many thanks,

What I have tried:

for x in range(0,len(nfy)):
if nfy[x]<nfy[x+1]:
="" print('raising')
="" elif="" nfy[x]="">nfy[x+1]:
print('falling')
