Trading by dollar amount:
Buy a stock according to the dollar amount you want When you buy a stock of your choice, you can enter the amount you want to invest. The amount you enter will then be converted into an estimated number of shares and the transaction will be executed at the most favorable price.

The system will sell you 1 cent less in shares, even though the amount will never be more than you specified.
