I was already using Datek as my broker before I decided to "day-trade". I know CyberCorp and Realtick software is better because it is Windows based, but it also costs $300 a month and I don't make that many trades since I don't do it full-time. If I ever go full-time, I'll use Realtick (or some broker that uses Realtick). I know I need to cut my losses. That is what I am learning to do now.
