I have tradestation, it is the best but it cost $$
Or open an account at Think or Swim, Quotes charts everything for free. Their options trading platform is the best there is without spending 2k a month.
You don't need real time unless you are trading?
This is also free, it is all you need and it is bad as hell, especially the screener FINVIZ.com - Stock Screener
depends on the feeds you get, I spend 135.0 month with an account. If you hit a certain # of trades it is free except you still pay for the data feeds.
I traded full time for years, was good at it, got cocky, made one big bet, lost hundreds of thousands, quit. That was in 2003, didnt' trade again until 2007. These days I trade occasional in the pre markets.
