how to find exponential weighted moving average using dataframe.ewma?

Question

Previously I used the following to calculate the ewma

dataset[\'26ema\'] = pd.ewma(dataset[\'price\'], span=26)

But, in the latest version

Answer 1

Use Series.ewm:

dataset['price'].ewm(span=26)

See GH11603 for the relevant PR and mapping of the old API to new ones.

Minimal Code Example

s = pd.Series(range(5))
s.ewm(span=3).mean()

0    0.000000
1    0.666667
2    1.428571
3    2.266667
4    3.161290
