Please refer to the API documentation below for the Option Chain, which includes option_greek data. You can filter the option data based on the delta value.
Also, please ensure you’re aware of the rate limiting applicable here.
Let us know if this resolves your query. Thank you!
In WebSocket, you cannot pass the expiry as an individual field. Instead, you need to group the instrument keys before subscribing to the WebSocket. To get any week’s expiry instrument keys, you can use the Put/Call Option Chain | Upstox Developer API.
