Well, that 400,000 buy order supported the shares trading above that level until the closing auction.
That was a great result for the share price, closing in the green, when the overall market was significantly down.
The fact that the sellers didnt sell into that buy shows there is limited selling pressure remaining at this price range.

In the closing auction it managed to buy a miserly 763 shares. It was then cancelled, looks like a "good for day" trade type.

Lets see if we get a "Change in directors interest" announcement over the next few days.
