Candlestick Chart

[dbrtechnopharma]

I want to modify this charts-https://canvasjs.com/python-charts/python-combination-charts/candlestick-line-chart/ according to my django web application views.py which is attached here. Please suggest me how I can do this? The candle stick chart will be shown as nifty 200 symobols historical data with json format.
views.py-import http.client
import json
import time
from django.shortcuts import render

def index(request):
name = ‘KothaEd’
stock_name = ‘ABB’
from_date = ‘240120T09:00:00’
to_date = ‘240129T18:30:00’
interval = ‘eod’

if ‘stockname’ in request.POST:
stock_name = request.POST[‘stockname’]
if ‘from_date’ in request.POST:
from_date = request.POST[‘from_date’]
if ‘to_date’ in request.POST:
to_date = request.POST[‘to_date’]
if ‘interval’ in request.POST:
interval = request.POST[‘interval’]

# Credentials
username = ‘wssand033’
password = ‘rajdip033′

# Get access token
conn = http.client.HTTPSConnection(“auth.truedata.in”)
payload = f’username={username}&password={password}&grant_type=password’
headers = {‘Content-Type’: ‘application/x-www-form-urlencoded’}
conn.request(“POST”, “/token”, payload, headers)
res = conn.getresponse()
data = res.read()
token_resp = json.loads(data.decode(“utf-8”))
access_token = token_resp.get(‘access_token’, None)

if access_token:
# Fetch historical data for the given symbol, from_date, to_date, and interval
connHistory = http.client.HTTPSConnection(“history.truedata.in”)
payload = ”
headers = {‘Authorization’: ‘Bearer ‘ + access_token}
endpoint = f”/getbars?symbol={stock_name}&from={from_date}&to={to_date}&response=json&interval={interval}”
connHistory.request(“GET”, endpoint, payload, headers)
res = connHistory.getresponse()
data = res.read().decode(“utf-8”)

# Simulate data fetching delay
time.sleep(1)

# Return render to print json data in the template
return render(request, ‘stocky/index.html’, {‘name’: name, ‘stockname’: stock_name, ‘from_date’: from_date, ‘to_date’: to_date, ‘interval’: interval, ‘data’: data})
else:
print(“Error: ‘access_token’ not found”)
return render(request, ‘stocky/index.html’, {‘error’: ‘Access token not found’})

@dbrtechnopharma,

In this example, we are reading data from /static/btc-usd-weekly-2021.json file. In your case, you can store the Nifty 200 data in a JSON format and pass it as datapoints to the chart.
