The 400k (10.7p) is a DMA bid order. He's bidding for 400k at 10.7 (the intention is to buy 400k at 10.7p, if he can. He's not a seller, he's a buyer so no, this is not holding the price back, quite the opposite. Of course DMA orders can be removed and placed upon the order book, it seems, at will. At times I believe they take the p--ss as it sends out false signals...
It's when there's heavy orders on the offer that can hold the price back
