I followed your logic. Sold at $4, looking at buy in at $3.30 (not too much farther to drop), then ride it back up to $3.75 and dump.
I adjusted the sell limit to $4 right at the open, once Dudd let the news fly. Now, please talk it down to $3.25 so that I can have lunch money for next week. I made a bundle today!

and sold today at $4. Thanks DD and Brexit for the lunch money. Just in time for the July 4th extravaganza!
