What broker do you use to buy and sell millions at a time? Schwab only lets me buy and sell 999,999 at one time - which means an $8.50 charge per million - and Scottrade allows me to buy as much as I want -BUT I can't list it to sell for more than 3 times list price. EX - Buy .0001 list only for .0003. NOT!!! Any suggestions?
