I beg to differ unless you have some type of banking system.
If one want to make a deposit before 5:pm and be able to trade by 7am EST
Scottrade from my experience has the service.
Etrade back in the day they use to be great with pennies Hey whatever that works for you.
Etrade deposit been with them for over 20 yrs...there deposit system works for them not the customers.
Brokers are a dime a dozen I tried several of them they are one of the worse to have your funds posted in less than 24 hrs without using one of there services.
