Index volume in TickByTick feed

I would like to get the volume for the NIFTY50-Index.

The volume is available in the 5sec/1min historic data.

How to get this using socket?

If not do you need to call historic data to get the latest with volume? Is there any ratelimit if poll the API continuously?

Hi @117565191322365789577 ,
At the moment, WebSocket doesn’t provide volume for index symbols. For index volume, you can use the History API.
You can check rate limits in the v3 documentation here:https://myapi.fyers.in/docsv3#tag/Request-and-Response-Structure/paths/~1pet~1%7BpetId%7D/post

We’ve noted your feedback on WebSocket support — thanks for sharing!

Is there any new update about this? How to get index volume from Socket
