Is there a web site that offers free market quotes for single stock futures from One Chicago?

Question

Even 20 minute delayed quotes?

Answer 1

Delayed quotes are available all over the web, although reuters.com and bloomberg.com are the biggest providers.

The reason you can't find anything more recent is that Exchanges charge high prices for up to the second trading data. Sometimes the price paid depends on the number of end users and it is also usual these days for the exchanges to force intermediaries to make you agree to their contract terms before making the data available. So if you do decide to pay for access you will find you have to click through pages of contracts from 5 or 6 exchanges and agree to their terms before the service is switched on.
