comparing 3 day old stochrsi with current stochrsi

Just started coding my first algo!

Question here is how do I compare the stochrsi from 3 days ago to the current stochrsi on a daily chart?

All advice appreciated!

Welcome, Dennis. I'm not sure exactly what you're looking for, but here's the super basic implementation of STOCHRSI.

(Ignore all the commented out stuff - that's leftover from a different algo I forgot to clean out).

Hi Dan, thanks for your response. What I want to know is if it is possible to compare the stochrsi value today to the stochrsi value from 3 days ago?

And I may be wrong, but isn't stochrsi supposed to return a float that oscillates between 0 and 1 instead of %d and %k?

@Dan,

Can you please add UserList to support in the near future?

I can think of using a circular list to store the most recent numbers.

stochrsi = ta.STOCHRSI()

import UserList

class Ring(UserList.UserList):  
    def __init__(self, data = []):  
        self.data = data  
        self.offset=0

    def turn(self, n=1):  
        self.offset = self.offset+n  
        while self.offset<0:  
            self.offset = self.offset + len(self.data)  
        while self.offset>=len(self.data):  
            self.offset = self.offset - len(self.data)

    def __getitem__(self, i):  
        if abs(i)>=len(self.data):  
            return self.data[i] # raise IndexError  
        return self.data[(i-self.offset)%len(self.data)]

    def append(self, x):  
        length = len(self.data)  
        while self.offset>=length:  
            self.offset = self.offset - length  
        self.data[length-self.offset:length-self.offset] = [x]  

Hi Dennis,

I think this is what you are trying to do. Hopefully it helps! I don't think there is a way to call the stochrsi function that excludes the most recent 3 days.
