Sugaree ... Charts etc
Technical chart/trading platforms like Interactive Brokers Tradestation, make sense if you're very active or day trading. I don't spend hours in front of my screens anymore so am ok with the basics just swing trading/investing through my bank online and using a chart service like Stockcharts.com
I'm not a fan of most web based trading applications that try to emulate professional platforms.
