I did for a while. I also used a scottrade account. I didn't realize how bad they were until I saw that they were having a hard time filling orders when i wanted them filled. Also, scottrade is notorious for creating a mess with the IRS. I was lucky enough to catch it early or it could have been alot worse than it was. In overall stock trading, I was told by a seasoned trader not to even think about it unless you have enough capital to go with Lever2. I think the requirement with scottrade on level 2 is 25,000.00. Short google, you might get lucky.:lue:
BTW, it is more expensive to trade OTC stocks than they advertise.
