What kind of data websocket is providing through ltt, ltp, ltq?

Websocket is providing these values named ltp, ltt, ltq. Is it live tick data? or is it snapshot data? or is it aggregated tick data.

I am more interested in quantity provided here. If I store the quantity provided here and then sum the quantity for a min? will it match the 1 min candle volume (for let say NIFTY FUTURE). or this quantity is only snapshot here and there might be case of missing quantity here.

If the quantity is missed how much is missed here? 1% or more. Any thoughts on this would be super helpful.

Thanks

I tried to store the data and did the sum of ‘ltq’ for each minute to confirm if it matches with the candle bars.

It did not match, so can I assume that its a snapshot and does not capture/aggregate the volumes.

Please let me know if thats the case.

Thanks
