Please can you tell me why live feed is empty today for nifty.
Can we use 20 instrument keys in array at a time for market live feed option chain.
Hello @bhuvanesh_waran,
Yes, you can subscribe to 20 instrument keys in an array for the market live feed option chain.
Regarding the empty feed received for Nifty, please note that if you are subscribing to the market feed for the option chain and passing NSE_INDEX|Nifty 50
as the instrument key, an empty feed will be returned, as Nifty is not an option.
To receive a live feed for Nifty 50, please subscribe to the market live feed in either full mode or LTPC mode.
For further details, please refer to our market feeder documentation.
Thank you.
Actually the keys have been changed passed expiry date. So the empty feed.
Can you tell me how to calculate oi change.
If you’re looking for Nifty index data, the key for the Nifty index remains unchanged. Currently, we don’t directly provide changes in OI. However, you can calculate OI changes using Full Market Quotes or OI from the websocket, but you’ll need to store the data on your end.
Thanks for reply, NSE_FO instrument keys have been changed for nifty 50 and are different from expiry date 24/10/24 and 31/10/24. So every time do we have to extract those changed keys for options livefeed. Pls can you tell me how many websocket connections are allowed per token or do we have to redirect it from our server to for client phone app. Can we delay incoming live feed data as it drains battery charge soon.
