Hi I was just trying out the [real time quote data](https://alpaca.markets/docs/python-sdk/market_data.html#subscribing-to-real-time-quote-data) function, and it doesn’t seem to run in Jupyter Notebook (VSCode), but seems to run fine as a .py file in PyCharm. from alpaca.data.live import CryptoDataStream from config import \* wss\_client = CryptoDataStream(API\_KEY, SECRET\_KEY) async def quote\_data\_handler(data): print(data) wss\_client.subscribe\_quotes(quote\_data\_handler, “BTC/USD”) wss\_client.run() This returns the error “ **RuntimeError** : asyncio.run() cannot be called from a running event loop”. Does anyone know how to troubleshoot this? Any help is appreciated. ---

Hey I don’t have a solution, but you can run the Python script in the terminal The notebook doesn’t work for me either Maybe it is an issue with the websocket and the async function Also, the notebook does not support multiprocessing sometimes So the asyc is kind of multiprocessing stuff
