Time to buy DNA!, page-113

I have bought in. Strangely I put a cheeky bid in at 31 cents for 4900 and had most of it taken in small bites of around 100 shares each, obviously not normal trading and in all now own 4450 odd shares, but looking at what the sp is now , i dont think the balance will be filled at 31 and report is good enough for me to have a nice smile . This is the first time i have had 95 per cent of order chomped, leaving a small balance on order. Can i just contact the broker and buy balance at market price or cancel balance outstanding?
Was it bot activity plus a couple of panicked investors that caused the drop to 31 cents today?. Funny went straight up afterwards.
