Hello,

I am trying to find out how to find a similar function "Xaverage" in python.

This is what I have in easylanguage: test = XAverage( Close, Length ) and I am trying to change it into python.

Thank you very much.

In pure Python, with NumPy, with another library?

In pure Python, with NumPy, with another library?

I have installed both libraries:
import matplotlib.pyplot as plt
# import numpy as np

either ones work for me. Thanks a lot.

XAverage is simply an exponential average. I am pretty sure that is either available already or you can easily program it or find code via google.

You can find good examples here.

An easy to understand one is:

 

Code

def moving_average(x, n, type):     x = np.asarray(x)     if type=='simple':         weights = np.ones(n)     else:         weights = np.exp(np.linspace(-1., 0., n))     weights /= weights.sum()     a =  np.convolve(x, weights, mode='full')[:len(x)]     a[:n] = a[n]     return a
