Hi.
Two requests for tickers:
api/v3/ticker/price - Latest price for a symbol or symbols.
api/v3/ticker/bookTicker - Best price/qty on the order book for a symbol or symbols.
But there is no volume and quoteVolume and ticker time is only last moment.

If I understand correctly, we should get a 24 hour ticker.
this api is fit:
