Hello!
I know the only one place to see CBOE futures live chart (10-15 delayed). It is on CNBC site.
Maybe anyone knows better CBOE source?
And where can I see CME futures live chart?
For all futures contracts, you have to pay a fee to the exchange to receive live data. In the case of the CME it is only $5 a month for a non-professional trader.
You can get 10 minute delayed data at
