"I heard that Swift traders use Quotetracker for their charts, and that they get their data from Ameritrade and each trader only pays $20 a year." There are 3 ways to get Quotetracker: (1) Free - Comes with 2 days, RT streaming quotes. Also has ads that take up space & slow it down. (2) Pay $70/Yr - Comes with 10 days RT streaming quotes...No ads...Feed data fraom any accepted source, i. e. Interactive Brokers, etc... (3) Have an open account at TD Ameritrade or Ameritrade iZone...Need a minimum balance of $2000. I have (3)...I love QuoteTracker!
