推荐答案

我也注意到了这一点并联系了 Alpha Vantage.我收到了这样的回复:

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

感谢您的联系！对于在纳斯达克上市的证券，例如 MSFT，我们的 API 平台上的数据每天都会在美国东部时间下午 4:30 刷新.

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.

因此看起来没有为纳斯达克上市项目提供实时数据.这可能是这里的问题.

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