I cannot get any NASDAQ data from the Alpha Vantage TIME_SERIES_DAILY, TIME_SERIES_DAILY_ADJUSTED or TIME_SERIES_INTRADAY -- the returned array is always empty regardless of the equity or index symbol I use:
{}
This is the call I made to get that array:
https://www.alphavantage.co/query?function=TIME_SERIES_DAILY_ADJUSTED&symbol=NASDAQ:^IXIC&interval=15min
Notice I've used the NASDAQ: prefix. I've also tried using NSQ: instead -- with exactly the same results. I don't get this issue when calling for LSE (LON:) or NYSE (NYSE:) data.
I've tried a range of valid and invalid equity ticker symbols (e.g. GOOGL, MSFT) with either the same empty array result returned (if a valid ticker) or an expected error message returned (if an invalid ticker).
Am I doing something wrong here? Is NASDAQ listed using some other random collection of letters?
I've noticed some inconsistency between real-life ticker symbols, and the AV ticker symbols -- often enough that I've created a translation table so I can represent domain-useful information rather than AV-useful information. I'm hoping I'm just using an incorrect or outdated reference to NASDAQ to call the API.
Your help is much appreciated in advance!
TLDR;
Just look up the symbol (ie. AAPL or GOOGL). The IXIC is an index, Alpha Vantage currently does not cover indexes.
Further notes:
Quotes from Alpha Vantage are aggregated, so any price you're getting won't be the price from what it's traded on the NASDAQ, but a quote of what the price is across exchanges.
If you're looking for a specific symbol, you can check for what it's listed as using the search endpoint.
