Hi, yes. By replacing highlighted in bold syntax in *screener.py* file we can extract yahoo data instead of quandl. After changing the code iam extracting NSE data from yahoo site without any issue. Also we need to install below packages for yahoo data. ################### code modfication require #################### class Stocker(): # Initialization requires a ticker symbol #def __init__(self, ticker, exchange='WIKI'): * def __init__(self, ticker, exchange='NS'): <-----replace with your tricker* # Enforce capitalization ticker = ticker.upper() # Symbol is used for labeling plots self.symbol = ticker # Use Personal Api Key # quandl.ApiConfig.api_key = 'YourKeyHere' # Retrieval the financial data try: * stock = web.DataReader(ticker, 'yahoo', start, end) <---- by using this we can extract yahoo data instead of quandl* ############################################install below packages for yahoo data extraction ############################################## (base) C:\Users\bathula>pip install pandas-datareader Collecting pandas-datareader Downloading https://files.pythonhosted.org/packages/cc/5c/ea5b6dcfd0f55c5fb1e37fb45335ec01cceca199b8a79339137f5ed269e0/pandas_datareader-0.7.0-py2.py3-none-any.whl (111kB) 100% || 112kB 443kB/s Requirement already satisfied: wrapt in c:\users\bathula\appdata\local\continuum\anaconda3\lib\site-packages (from pandas-datareader) (1.10.11) Requirement already satisfied: requests>=2.3.0 in c:\users\bathula\appdata\local\continuum\anaconda3\lib\site-packages (from pandas-datareader) (2.19.1) Requirement already satisfied: lxml in c:\users\bathula\appdata\local\continuum\anaconda3\lib\site-packages (from pandas-datareader) (4.2.5) Requirement already satisfied: pandas>=0.19.2 in c:\users\bathula\appdata\local\continuum\anaconda3\lib\site-packages (from pandas-datareader) (0.23.4) Requirement already satisfied: idna<2.8,>=2.5 in c:\users\bathula\appdata\local\continuum\anaconda3\lib\site-packages (from requests>=2.3.0->pandas-datareader) (2.7) Requirement already satisfied: urllib3<1.24,>=1.21.1 in c:\users\bathula\appdata\local\continuum\anaconda3\lib\site-packages (from requests>=2.3.0->pandas-datareader) (1.23) Requirement already satisfied: chardet<3.1.0,>=3.0.2 in c:\users\bathula\appdata\local\continuum\anaconda3\lib\site-packages (from requests>=2.3.0->pandas-datareader) (3.0.4) Requirement already satisfied: certifi>=2017.4.17 in c:\users\bathula\appdata\local\continuum\anaconda3\lib\site-packages (from requests>=2.3.0->pandas-datareader) (2018.10.15) Requirement already satisfied: python-dateutil>=2.5.0 in c:\users\bathula\appdata\local\continuum\anaconda3\lib\site-packages (from pandas>=0.19.2->pandas-datareader) (2.7.5) Requirement already satisfied: pytz>=2011k in c:\users\bathula\appdata\local\continuum\anaconda3\lib\site-packages (from pandas>=0.19.2->pandas-datareader) (2018.7) Requirement already satisfied: numpy>=1.9.0 in c:\users\bathula\appdata\local\continuum\anaconda3\lib\site-packages (from pandas>=0.19.2->pandas-datareader) (1.15.3) Requirement already satisfied: six>=1.5 in c:\users\bathula\appdata\local\continuum\anaconda3\lib\site-packages (from python-dateutil>=2.5.0->pandas>=0.19.2->pandas-datareader) (1.11.0) Installing collected packages: pandas-datareader Successfully installed pandas-datareader-0.7.0 (base) C:\Users\bathula> (base) C:\Users\bathula>pip install BeautifulSoup4 Requirement already satisfied: BeautifulSoup4 in c:\users\bathula\appdata\local\continuum\anaconda3\lib\site-packages (4.6.3) (base) C:\Users\bathula>pip install scikit-learn Requirement already satisfied: scikit-learn in c:\users\bathula\appdata\local\continuum\anaconda3\lib\site-packages (0.20.0) Requirement already satisfied: numpy>=1.8.2 in c:\users\bathula\appdata\local\continuum\anaconda3\lib\site-packages (from scikit-learn) (1.15.3) Requirement already satisfied: scipy>=0.13.3 in c:\users\bathula\appdata\local\continuum\anaconda3\lib\site-packages (from scikit-learn) (1.1.0) (base) C:\Users\bathula>pip install sklearn Collecting sklearn Downloading https://files.pythonhosted.org/packages/1e/7a/dbb3be0ce9bd5c8b7e3d87328e79063f8b263b2b1bfa4774cb1147bfcd3f/sklearn-0.0.tar.gz Requirement already satisfied: scikit-learn in c:\users\bathula\appdata\local\continuum\anaconda3\lib\site-packages (from sklearn) (0.20.0) Requirement already satisfied: numpy>=1.8.2 in c:\users\bathula\appdata\local\continuum\anaconda3\lib\site-packages (from scikit-learn->sklearn) (1.15.3) Requirement already satisfied: scipy>=0.13.3 in c:\users\bathula\appdata\local\continuum\anaconda3\lib\site-packages (from scikit-learn->sklearn) (1.1.0) Building wheels for collected packages: sklearn Running setup.py bdist_wheel for sklearn ... done Stored in directory: C:\Users\bathula\AppData\Local\pip\Cache\wheels\76\03\bb\589d421d27431bcd2c6da284d5f2286c8e3b2ea3cf1594c074 Successfully built sklearn Installing collected packages: sklearn Successfully installed sklearn-0.0 (base) C:\Users\bathula> ########################################################################## Regards, Bathlua

Here is the full code:

import pandas_datareader.data as web
import datetime

# Class for analyzing and (attempting) to predict future prices
# Contains a number of visualizations and analysis methods
class Stocker():
    
    # Initialization requires a ticker symbol
    def __init__(self, ticker, exchange='NS'):
        
        # Enforce capitalization
        ticker = ticker.upper()
        
        # Symbol is used for labeling plots
        self.symbol = ticker
        
        # Use Personal Api Key
        # quandl.ApiConfig.api_key = 'YourKeyHere'

        # Retrieval the financial data
        try:
            #stock = quandl.get('%s/%s' % (exchange, ticker))
            start = datetime.datetime(2000, 1, 1)
            end = datetime.datetime.now()
            stock = web.DataReader(ticker, 'yahoo', start, end)
