๐ง Quick Start
Simple WebSocket Manager Usage
import asyncio
from aiopybit import ByBitClient
client = ByBitClient(API_KEY, API_SECRET, MODE)
async def handle_ticker(data):
ticker = data.get('data', {})
symbol = ticker.get('symbol', 'N/A')
price = ticker.get('lastPrice', 'N/A')
print(f'๐ {symbol}: ${price}')
async def main():
await client.ws.subscribe_to_ticker(
category='spot', symbol='BTCUSDT', on_message=handle_ticker
)
try:
while True:
await asyncio.sleep(1)
except KeyboardInterrupt:
pass
await client.close()
if __name__ == '__main__':
asyncio.run(main())
