Prohodnay Baza's questions

请告诉我如何获取开盘价、收盘价等。不要严格评判，我只是在学习。获得交易所MEXC Ticker。

import asyncio
import json
import websockets

async def mrlsv_ws():
    url = 'wss://wbs.mexc.com/ws'
    async with websockets.connect(url) as ws:
        print('Connected')
        subs = dict(
            method = 'SUBSCRIPTION',
            params = [
                '[email protected]@BTCUSDT@Min30'
            ]
        )
        await ws.send(json.dumps(subs))
        async for msg in ws:
           
            msg = json.loads(msg)
            symbol = msg.get('s')
            print(symbol)

if __name__ == '__main__':
    asyncio.run(mrlsv_ws())

{
  'd': {
       'e': '[email protected]', 
       'k': {
             't': 1732906800, 
             'o': '97176',
             'c': '97047.99', 
             'h': '97190.48', 
             'l': '96879.53',

             'a': '7276917.78', 
             'T': 1732908600, 
             'i': 'Min30'
             }
        }, 
   'c': '[email protected]@BTCUSDT@Min30',
   't': 1732908001686, 
   's': 'BTCUSDT'
}
