i've been trading this stock for the past month now. Been making some good cash on it. only tid bits are...first and last half hour of the day,it moves violently up and down with 2 and sometimes 3 cent spreads on the bid and ask.gotta be very careful. other than that, it moves at a fairly normal rate.not too fast,but not too slow. has an avg volume anywhere from 7-15million tops.pennies are easy to catch. Redi/Arca gets hit a lot. i'll ride this one out till it starts acting like JDSU lol. (don't ask)
