The last thing you want to do with an OTC stock is place a market order versus a limit. Execute a few of those and sooner or later you will see why it isn't a great idea.
Yes, I traded thru schwab everyday this week, both market and limit on amep without a restriction or a problem...I would love to know who at etrade made the decision to restrict on line buying and WHY....I smell a rat at etrade that spilled over to a couple others. If i had an account at etrade I would raise serious questions of the district or regional manager as to who instituted the rediculous restriction.
