I m working on a stock prediction project. This is how I want:

To show all the stocks available in Nifty50, Nifty100 or so and then the user will select the stock to predict the high and low price of a stock on next day only.

I m using Django.

What I have done till now: I m able to display a list of stock.

def index(request):
    api_key = 'myAPI_Key'

    url50 = 'https://archives.nseindia.com/content/indices/ind_nifty50list.csv'
    url100 = 'https://archives.nseindia.com/content/indices/ind_nifty100list.csv'
    url200 = 'https://archives.nseindia.com/content/indices/ind_nifty200list.csv'

    sfifty = requests.get(url50).content
    shundred = requests.get(url100).content
    stwohundred = requests.get(url200).content

    nifty50 = pd.read_csv(io.StringIO(sfifty.decode('utf-8')))
    nifty100 = pd.read_csv(io.StringIO(shundred.decode('utf-8')))
    nifty200 = pd.read_csv(io.StringIO(stwohundred.decode('utf-8')))

    nifty50 = nifty50['Symbol']
    nifty100 = nifty100['Symbol']
    nifty200 = nifty200['Symbol']



    context = {
        'fifty': nifty50,
        'hundred': nifty100,
        'twohundred': nifty200
               }

    return render(request, 'StockPrediction/index.html', context)

What I want: I want to get the live data of all stocks open, high,LTP,Change, Volume.by mean of live data is that it will change as per stock values will change.

Please Help!

You must combine Ajax/Jquery like code below to periodically get data and update values in DOM :

(function getStocks() {
    $.ajax({
            type: "GET",
            url: "url to your view",
            success: function (data) {
                // here you can get data from backend and do changes like
                // changing color by the data coming from your view.
            }
        }).then(function() {           // on completion, restart
       setTimeout(getStocks, 30000);  // function refers to itself
    });
})();

But be careful about making too requests, you must choose proper interval right in this line setTimeout(getStocks, "proper interval");

And in your view you should put queries into a JSON format something like this :

return JsonResponse({'stocks': stocks})

here stocks must be in json format.
