How do I use websocket to update K-line data?

[lei1996]

example： 15min I first get the historical data through the gethistoricalprices interface, and then push the latest data through WS 15 minutes later?

I don't want to request the HTTP interface in 15 minutes, because there will be other problems.

I don't think FTX provides a kline channel. If you'd like official confirmation you could try asking on their API channel in telegram: https://t.me/ftx_api_support

What you could do instead is subscribe to the trades topic and build your own candles.
