I want to explore/experiment by creating indicators based off price action of various index members (S&P 500, R2K...etc)

What's a reliable way of getting this data and make sure it is kept updated?

Somewhat related, how would I go listing/query the API for all US Equities? From the docs it seems like I could do a query for A*, B*, ...etc but wondering if there is a more efficient way.

Thanks!

Hello, we do not have listings of constituents available. As for your other question about getting a list of all symbols in a specific market, you have two options.

The first option is that we publish a text file of every active symbol in our system daily here:
www.dtniq.com/product/mktsymbols_v2.zip
You can parse that file to pull out whichever market(s) you need.

Alternatively, you can filter the symbol lookup requests in the API by security type or listed market (multiple markets can be sent space delimited) and just use a * wildcard in the search field to get a list from each market.

Thanks!

Please consider adding constituent data. It would be interesting, and I' sure other people have that need.
