Even if you double the offscreen sell volume in BBG to say 40,000 shares....no one is going to sell a summer stock at key support (10.00) if they dont have too....so there is unlikely to be anymore "true" selling today anyway...
The laws of probability say that...now the short seller/dumper used only 100,000 or so shares to move BBG so far so soon....so 30,000 or so shares could easily move it back to 10.20.
In fact as there is there is so very few shares and someone could move it all the way to 10.30 very easily...but 10.20 ish makes sense as truly achievable target for today.
There is an offscreen buyer there ....maybe he is short covering in small parcels...one buyer and this explodes up.
