which method can get the tick fast and accurate, http or websocket?

API Spot/Margin API

we can use http and socket to get the tick info, http is
"GET /api/v3/ticker/bookTicker"
websocket is Stream Name: <symbol>@bookTicker
I used to use websocket because I though the websocket are not like the http “3-way handshark”. but the websocket are usually error like that

Hi, I would recommend web socket to be faster and avoid accumulation of request weight per IP.
Are you following the guidance to make the web socket alive? Please head to this page to read more: https://binance-docs.github.io/apidocs/spot/en/#websocket-market-streams
