Im trying to use bta-lib to calculate rsi indicator although it was fine with the sma function but through an error on rsi function
'''
df=pd.read_csv('prices.csv')
sma=btalib.sma(df,period=9)#works fine
rsi=btalib.rsi(df,period=14)#through an error
'''
error= ValueError: cannot set using a slice indexer with a different length than the value... my df len is enough.
