Does the streaming API still work?

I’ve followed the docs on your main github page, but my subscriptions to quotes/updates/etc doesn’t work. I receive a successful authentication message, but when I try to subscribe for quotes, I never get any notifications.

The docs on alpaca’s site it shows something like this, but I don’t see anything related to subscribing for updates.

{
    "action": "listen",
    "data": {
        "streams": ["trade_updates"]
    }
}

But in your example, the action is “subscribe” and the data doesn’t appear to be formatted in a similar format. I’m not sure what I’m missing…

Here is my code for connecting to the socket

this.socketConnection.once("authenticated", () => {
      this.socketConnection.subscribe("quotes", ["AAPL, FB, SPY"]);

      this.socketConnection.on("quote", (quote) => {
        console.log(quote);
      });

      this.socketConnection.on("bar", (bar) => {
        console.log(bar);
      });

      this.socketConnection.on("trade", (trade) => {
        console.log(trade);
      });

      this.socketConnection.on("trade_updates", (update) => {
        console.log(update);
      });
});`

Wow, I’m not sure how I missed the quotes needing to be individual strings. That seemed to be the issue. I did have market_data, just showed you the wrong one in the example. Thanks for taking the time to help with this! This library has been really helpful

In your socket connection you pass the array of quotes as one string:

["AAPL, FB, SPY"]

This is incorrect they should be individual strings:

["AAPL", "FB", "SPY"]

It is also important that you switch the type to market_data in the AlpacaStream constructor. If quotes is what you wish to receive, the example below works for me:

const stream = new AlpacaStream({
  credentials: {
    key: 'myKey',
    secret: 'mySecret',
  },
  type: 'market_data',
})

stream.once('authenticated', () =>
  stream.subscribe('quotes', ['AAPL', 'FB', 'SPY']),
)

stream.on('subscription', ({ quotes }) =>
  console.log(`subscribed to ${quotes.join(',')}`),
)

stream.on('quote', (quote) => console.log(quote))

I get the following output when running the above code:

subscribed to SPY,AAPL,FB

Hope this ends up working for you. 😃
