Quote from bronks:
Don, can you be more specific between Echo & Swift.
You can air it out here, or PM.
Quick summary..
Swift, co-owned by my friend Charles Kim and Peter Berg has a special arrangement with a clearing firm to have a single price "ticket charge" for each symbol they trade (basically). They have traders who are taught to trade for liqudiity rebates (primarily)...traders learn to play a very quick "video game." Traders keep a small percentage of the net profits. I just had 2 traders from there here for 2 weeks in boot camp, still pretty much the same deal.
Echo (formed similarly to Bright).... traders are licensed professionals who put up capital and keep their profits.
