Fail to get real time prices from Alpha Vantage API. Prices are one day old

问题

I am trying to get the latest Intraday prices from Alpha Vantage API. Currently it is Friday, 9:16PM Eastern European Time. I am trying to get Tesla stock. Markets are still open. However, The API call returns me yesterday's data only. What could be the problem?

ts = TimeSeries(key='API_KEY', output_format='pandas')
data, meta_data = ts.get_intraday(symbol='TSLA',interval='1min', outputsize='full')
print(data.head(5))
print(meta_data)

I had the same problem and wasn't able to solve it yet. But in my case only some stocks are not up to date. For example 'IBM' is up to date but 'TSLA' and 'AAPL' not. I also have written an email to the technical support 2 days ago. If I ever get a response with the explanation I will write you. I have checked this not only with the python module also with the direct API call.

I also noticed this and contacted Alpha Vantage. I got this response:

Thank you for reaching out! For Nasdaq-listed securities such as MSFT, the data is refreshed daily at 4:30pm ET on our API platform.

So looks like real-time data is not provided for Nasdaq-listed items. This could be the issue here.
