scottrade is the best, plain and simple. PM me and I will give you a great site where you can trend stocks. I've trended many that say at .002 and ran to .10 in a day and back down, so you need to get in early and pull the trigger early.
There's a millionaire Canadian penny trader who was asked what his secret was and he said "I always sold early" . The key is when you see a trend you have no idea when a run will stop. if all of a sudden a stock at a penny runs to .50 and everyone is yelling that a $1 is next, most sheep wait and potentially watch the stock drop again. Pick your selling point and sell no matter what, take your earnings and never look back. If you always wait for the big knockout punch you will always lose money in the long run.
