The kama indicator works halfway through my data set then suddenly stops giving only NaNs afterwords.
I am using it as:
ta_kama = KAMAIndicator(close=df['close'])
df['kama'] = ta_kama.kama()
The dataframe ['datetime', 'close', 'kama'] where it suddenly stops looks like:

I was wondering if I was using the library in a wrong way, but it looks like I encountered the same bug.
