Getting Real time OI data

import requests

Access Token obtained after successful authorization

access_token = open(‘access_token.txt’, ‘r’).read().strip()

URLs for fetching Option Chain data

url_bnf = ‘
url_nf = ‘

def get_oi_data(url):
headers = {
‘accept’: ‘application/json’,
‘Api-Version’: ‘2.0’,
‘Authorization’: f’Bearer {access_token}’
response = requests.get(url, headers=headers)
if response.status_code == 200:
return response.json()
print(f"Failed to fetch data. Status Code: {response.status_code}")
return None

oi_data = get_oi_data(url)
if oi_data:
data = oi_data.get(‘data’)
if data:
for item in data:
expiry_date = item.get(‘expiryDate’)
strike_price = item.get(‘strikePrice’)
ce_open_interest = item[‘CE’].get(‘openInterest’)
pe_open_interest = item[‘PE’].get(‘openInterest’)

Store OI data for Bank Nifty and Nifty

store_oi_data(url_nf, ‘NIFTY’)
store_oi_data(url_bnf, ‘BANKNIFTY’)

We have received your request regarding the availability of option chain data through the Upstox API. Currently, this feature is not yet available. However, we are actively working on it and it is a part of our future development plans. We will make sure to inform you as soon as it becomes accessible.

In the meantime, you can access real-time OI data using our WebSocket. Detailed information for using the WebSocket can be found at Upstox API Documentation and the WebSocket examples are available on our GitHub page at Upstox Python WebSocket Examples.
