I have subscribed to historical data api and I am trying to calculate RSI value for list of stock at EOD. I wrote the below piece of code to calculate RSI value.
def RSI(df, base, period , script_name,xls_row): """ Function to compute Relative Strength Index (RSI)
Args : df : Pandas DataFrame which contains ['date', 'open', 'high', 'low', 'close', 'volume'] columns base : String indicating the column name from which the MACD needs to be computed from (Default Close) period : Integer indicates the period of computation in terms of number of candles
Returns : df : Pandas DataFrame with new columns added for Relative Strength Index (RSI_$period) """
I checked for few stocks and below is my observation: For "ABBOTINDIA" period: 14 , interval = "day" and RSI is calucalted on "close" price. RSI from kite app = 39.72 on 18/11/2020 closing basis RSI calculated from above formula = 28.29 on 18/11/2020. Please let me know the formula which I am using above is correct for calculating RSI?
