Hi Mridul,



In the 'Bollinger_Bands' function in cell 4, we passed two parameters data and lookback period (n). While calculating the moving average and standard deviation, we passed the 'Close' column with the data. So, when you call the 'Bollinger_Bands' function, it will do the calculation using the 'Close' column of the dataframe.



Hope that helps.
