What is the TWS symbols for major U.S. stock indices

What are the TWS symbols for NASDAQ Composite, Dow Jones Industrial Average, and S&P 500?

I currently subscribed to "US Securities Snapshot and Futures Value Bundle" and "US Futures Value Bundle PLUS"

 

Just type "NQ" "YM" or "ES" (without the quotes) and then press enter and choose which instrument/exchanges you want. There is a menu and sub-menu system for instrument selection in TWS.

 

I try to get real-time index chart and quote. I got "INDU" for Dow Jones Industrial Average, "SPX" for S&P 500. "INDU" and "SPX" both don't show "Change" and "Chg %", but have real-time chart. I didn't get anything for NASDAQ Composite.

 

Need to use a Watchlist to get "Chg %" or "Change" I think. Also, the NDX is a separate data feed. You have to subscribe to NASDAQ specifically.

 

Here is the list I use with the avg price moves.

 

Are those excel spreadsheets? Pretty cool

 

I am looking for index itself, not the futures on it.
