Be careful with ACH deposits at Ameritrade. They take time to set up and verify. Also, I believe you can NOT use such deposits for nonmarginable securities for 5 days. The funds can be used to purchase marginable securities immediately but not most otcs. I know you're just using it to get the $15 fee covered. Just be sure to check out all options explicitly.
lasombra- Yes my personal account is set up that way, but my buddies account is not and I think you have to have the transfer set up from your own personal checking or savings, But since my friend is out of the country I mailed a deposit form and a check from me to deposit in his account, I will be calling ameritrade shortly for best way to get money to them.Thanks for your suggestion.
