30000 27 27.5 40000
15000 27 27.5 25000
20000 27 27.5 50000
100000 27 27.5 10000
40000 27 27.5 100000

9116 27 27.5 126863
100000 27 27.5 100000

2 lots of 29,000 are then bought at 27.5 for at total of 58,000 shares

27.5 29000 14:15.14
27.5 29000 14:14.56

Then what happens is that the above sell order for 126863 automatically gets transferred to the back of the line at 27.5 but now has an extra 58,000 shares added on to it to make it 184863.
It seems they really dont want to sell but want to give the impression that there is a huge supply at 27.5
