I can see the live trading data, including all orders in the queues, in real time, on my trading platform (via BellDirect).
Below is a screenshot I took from my phone just after 4pm, when the 905k order was in at 88c.
At about 4.09pm it shifted to 91c as there wasn’t quite enough corresponding sell volume for it all to be filled. My conclusion is that whoever placed the order, wanted it all met, and therefore ended up paying the extra 1c per share ($9k) for that to happen (they all went through at 89c in the end). Iirc all but about 30k shares were filled at 88c at 4.09pm, but it appears that they then upped the price to ensure they would all get bought.
Coughing up the additional $9k to ensure the last 30k shares were bought, seems interesting to me! Hence I reckon/guess that they were shorts needing to be covered and returned. Or perhaps just expecting a big day Monday?!
