Websocket market streams: getting a total quantity traded per the update period

My goal is to listen data stream and calculate the statistics of the traded quantity

I thought listening individual symbol ticker would be good for me:

But as i can see from the docs, the stream sends data each 1000 ms and there is no info about traded quantity for this period. I can see the last quantity only (“Q” field), but i need a full quantity per 1000 ms.
So I need the field which says: “for this 1000 ms period quantity = xxx”

Is there any way to get data I need?

The closest solution would be the 1s kline, <symbol>@kline_1s, where you can get the trading volume in that 1s time period.
