Cheapest offer for S&P500 index live quotes ?

I only need SPX quotes and charts , what are the best deal’s out there ?

 

For the index? You can find that for free anywhere!

 

I found one at investing.com but I dont know how reliable that free feed is..it also does not seem to update every second

 

Check out Tradingview.

 

any brokerage platform has that for free.

 

any futures platform ?

 

no, ^spx you have to pay for it.

 

End of day or intraday real time?

 

Intraday , real time

 

My Schwab account has real time $SPX for free.

You can trade futures on their ToS platform. I've never used it since I use my Interactive Brokers account for trading futures.
