I am going to change Brokers soon. Right now I am with E*Trade Pro (paying lower than posted rates as I was a Brown & Co. trader when they were merged several years ago). I am going either with Lightspeed or maybe RealFast Trader (apparently associated with Stock USA). The rates are pretty much the same (.40 per 100 share) although platforms are different. I have test driven Lightspeed and will do the same for RealFast Trader (DAS TraderPro) this week. I average only about 5,000 shares a day usually trading only SMH,XLF, and GDX etfs. Any thoughts? Thanks in advance.
