Scottrade these days makes you put an order by phone whenever any stock gains more than 100% in a day. It's all the stocks that gain over 100%, not just SFNN. They do this to protect the regular investors from daytraders and their pump tactics. Daytrader rarely call in their order because they normally buy and sell the same day after a pump/hype etc. However, since SFNN is trading by fundamental, and since it is not a hyped stock, I would take the effort to call and make the order if I were you.
