Hi, decision lies between Cybertrader and Ameritrade. I am going to do 12000 to 100000 shares orders. I guess market orders will be more appropriate. No daytrading but in many cases I will need to take intraday actions. (average position holding period ranges from 2 days to 1.5 weeks) being a newbie and therefore never being through order excecution and other aspects of various broker distinguishing features, I do see some differences between the two but I do not quite understand them (absense of experience). is direct access the only one crutial difference between the two? why is it so important to have a direct access? why, in terms of comissions, Ameritrade is so cheap when compared to Cyber? (to me, average comission at Cyber will be $200 for one side trade whereas Ameritrade promisess $11 if I understand right) I want to know why traders prefer Cyber - like brokers to Ameritrade-like brokers before I make a final step. I really need a good advise on this one. I would very appreciate comments of experienced traders.
