What I´m doing wrong with Finta EMA

[ghost]

Hi guys, sorry for the silly question but I'm doing something wrong and not able to figure out what is... Can you help me?

I´m working in Google Colab, have columns name as you suggested, add a 50 period but not getting the same info as the other libraries and the same info as manually calculate, I have something wrong but have any idea....

This is the code:

df_1['Finta_ema_50'] = TA.EMA(df_1,period=50)
