I just spoke with IQ Feed: The API is $444/annual (have to pay at beginning of year- comes out to $37/month) The iqfeed data with real-time stocks and futures is $112/month + exchange fees Stocks (NYSE $7, Nasdaq $7, AMEX $7, OTC $10) Futures (CBOT, CME, COMEX and NYMEX) for a total exchange fee of just $5/month So total net effective comes out to $185 / month - but limited to 500 symbols You can go up to 2500 symbols - cost goes from $185 to $467/month Will get some additional pricing from other providers and will share what I find here
Barchart - API is not geared towards retail customers and they couldn't give a quote right off the bat.
Www.dxfeed.com have a datafeed and a programmable scanner https://www.dxfeed.com/dxfeed-radar/ I think it is pc side.
You should check out InvestorRT at linnsoft.com. Good for building large watchlists (They call them Quote Pages) with easily coded signals in real time.
Here's the response I got: "API data access is a dedicated service, I'm afraid we do not offer it via our Retail portal get.dxfeed.com at the moment. Right now via our Retail portal you can only get the data for our partners software (ATAS trading platform). Therefore I have forwarded your request to our sales team, they should get back to you with more details. dxFeed Radar is not a standalone application, it is a service that can be connected to your own application or website via a set of APIs. You can try it at https://radar.dxfeed.com/" I'm not really sure what this means - but for now I am going to say that this does not do what I need it to do
