Description

When I try to use watch_balance for mexc, I get no message back at all. Like no error, no message, anything... I've tried to change balance while the script is running to see if it behaves like a ticker, but I didn't get any message. Then I tried to change watch_balance to fetch_balance and I got my balance message. So REST api works but websocket is not working. So it's not a apikey issue either. I really need to use watch_balance for mexc because fetch is too slow. Did someone have any problem like that?
Thank you in advance!

Code

import ccxt.pro as ccxt
import config_shawy
import asyncio

exchange_id = "mexc"
exchange_class = getattr(ccxt, exchange_id)
exchange = exchange_class({
    'apiKey': getattr(config_shawy, f'{exchange_id}_pub_key'),
    'secret': getattr(config_shawy, f'{exchange_id}_priv_key'),
    'enableRateLimit': True
})

async def watch_balance():
    if exchange.has['watchBalance']:
        while True:
            try:
                balance = await exchange.watch_balance({'type' : 'spot'})
                print(balance)
            except Exception as e:
                print(e)
                # stop the loop on exception or leave it commented to retry
                # raise e
    else:
        print("exchange has no watch balance mode")

async def main():
    await watch_balance()

if __name__ == "__main__":
    asyncio.run(main())

@BEEBSDONE it works for me, I got message when transfer USDT from spot to swap wallet. How do you change your spot balance?
