Affordable Delayed Data Feed From Web Service

Hi,

I've been searching around for the past 2 hours, and cannot seem to find an answer. I'm looking for an affordable delayed (15-30min) data feed that is available over the Internet. I don't want to be tied to a proprietary native API (ie no Windows libraries that have to be downloaded).

Also I need something that exposes its data in a format that's easily consumable by an application, like XML, JSON, etc.

Thanks!

esignal on demand

Clearly I'm missing something. I've researched eSignal On Demand before I posted my question. I cannot seem to find any info on how their data will be accessed without using their Windows application.

Can you maybe clarify how I will access the info in an open format over the Internet?

What periodicity do you seek? (tick feed, 1 min, 5 min, daily etc.)
Which markets?
Do you want a delayed streaming service of ALL symbols or just a subset?
Or do you just want to be able to query-on-demand a symbol at a time?

Thank you for your reply Richard.

Periodicity would be daily: Close, High, Low, Volume, Open, etc, but for the current day I'd like to get the last traded price info, about 20min delayed. Typically what you'll find from Google Finance, Yahoo Finance and FT.com. The only thing is that I require a proper API to work with so that I can navigate my way through the info. For example, I'd like to drill down to NYSE energy companies & query each one at a time, or get them in one go.

Markets: I'm willing to adjust my markets to whatever a well designed web API provides. But it would be huge plus if I can get Johannesburg & Singapore Stocks.

I'm flexible in this regard. A streaming service of ALL symbols might be overkill, so a subset is preferable. Querying a symbol at a time is also fine, IF there's a good way to discover symbols. In other words, if I'm querying a symbol at a time, I have to be able to first get a list of say NYSE energy utilities, and then query each one at a time to get it's data.

Thank you Trading Spaces. IQFeed comes close to what I'm looking for, but it still requires a very basic Windows exe to be installed for some COM based TCP/sockets access... or am I wrong?

Since you want daily data progressively updated intraday, you'll also need to define the frequency of updates?

i.e. do you simply want to query it on-demand and how many securities per minute would you need etc.

if you want a subset of securities coming down, how many do you need any how often do you want them updated? eg. 500 symbols, updated once a minute. eg. 500 symbols, updated every tick.

eSignal Pro allows streaming capability too and an API is available.

There's quite a few on-demand web-based data providers - QuoteMedia, Markit etc.

The windows API solutions are aimed at the advanced trader. However, you get far more superior capability when you look at institutional feeds such as nxCore.
