After your informative post, I did some DD and took a flyer in Acusphere. Luckily, I waited a couple days and got it at .45 and am money good so far. Only 10K. It is a nice feeling knowing I my bio-drug purchase will soar or crash during my lifetime.
scstocks, Thanks. Don't know why I thought Yahoo info would be usable. I guess ECN is just part of the overall picture, which, as they say, can be dangerous (a little bit of knowledge).
