When I am using the code:



delta = df['Close'].diff

dUP, dDown = delta.copy(), delta.copy()



it is giving the error 

'function' object has no attribute 'copy'

What is the solution?

Hello Ashish,



You need to use: 



delta = df['Close'].diff()



instead of:



delta = df['Close'].diff





As diff() makes sure the function is called and the calculated dataframe/series is returned. While diff is just a reference to the diff function object.
