Scottrade does not accept market orders on penny stocks. However you can put in a limit order which will trigger a buy at or below your designated limit price. The limit price is simply saying this is the most I want to pay for xyz stock. If the price is lower than your limit price it will be filled accordingly. As far as selling try a trailing stop price which will trigger a sale at or below your designated price. Hope this helps.
