your post never mentions the need to borrow the stock, here is your quote again
"This is how it works, an insitution has agreed to buy lets say 50m shares, they don`t trade until 15th., but that is immaterial, they sell them short NOW(not having any) tomorrow @ say 3.5p, quite legit, they then take up their 50m buy at 2.5p and settle - get my drift????"
You also do not explain how an institution sells 50m shares at 3.5p when the nms is less than 100k. My theory is you are making it up as you go along and DHAFC
