Ameritrade miight not be the lowest, but it's pretty fair. In the neighborhood of $11 a trade. Determine if you are going to require the advice of a broker often or if you are going to make your own picks. Avoid many of the older financial, cause they charge like $40 a trade, which is way too much. Check the rate they charge for transfers and account maintainence, and the interest rate they charge for margin. The margin rate will more than likely be tiered, depending on the value of the account and the amount of margin out.
Day trading can be a scary thing. even if you ko what you're doing. Good luck
