I would just like to be blunt here. What is the catch? It seems that Bright is offering lower commissions, better leverage, ect. If I have $100k, trade 100 share lots many times a day for many different stocks, why should I go to say IB, instead of Bright? (100 share lots means it is better to go for a penny a share fill, rather than a flat rate.) There must be a cost somewhere, but I haven't gotten it yet. Can I trade with Bright from home?
