Market Data Streaming Help

Hi y’all,

I have been trying to stream market data using the example in the Alpaca python API, but I keep getting the error that ‘Key ID must be given to access Alpaca trade API’, ’ (env: APCA_API_KEY_ID)’. I have tried creating environmental variables but it didn’t seem to help. Can someone please help me?

Hi,
use this as a template for your code, I think it will help you (note that you set your credentials in the file):

github.com

alpacahq/alpaca-trade-api-python/blob/add_simple_stream_example/examples/websocket_example.py

from alpaca_trade_api import StreamConn
from alpaca_trade_api.common import URL


ALPACA_API_KEY = "<YOUR-API-KEY>"
ALPACA_SECRET_KEY = "<YOUR-SECRET-KEY>"
USE_POLYGON = False


if __name__ == '__main__':
    import logging

    logging.basicConfig(format='%(asctime)s %(message)s', level=logging.INFO)
    conn = StreamConn(
            ALPACA_API_KEY,
            ALPACA_SECRET_KEY,
            base_url=URL('https://paper-api.alpaca.markets'),
            data_url=URL('https://data.alpaca.markets'),
            # data_url=URL('ws://127.0.0.1:8765'),
            data_stream='polygon' if USE_POLYGON else 'alpacadatav1'
