Where to get demo acct for s&p 500?

Lookn to practice some strategies and need a demo acct that gives real time readings with the s&p500,can anyone help?

 

openecry has one for 2 weeks free. After that you have to pay $25 / month I believe.

 

Think or swim has a free demo account. If you want you can do it through the CBOE hoe page- join up (free) then go to papertrade.
