depends on what your trading...and if you need charting. Tradestation is A+ for charting, if you trade futures their margins suck , forex spread is ok. If you trade futures try globalfutures they have good rates and lots of different platforms...I just use J-trader but there are other ones ,just depends on what your doing. For Forex , I use FXCM standard platform , you can use metatrader w/them as well.
