Boys.

You may want check the market depth and pay particular attention to the order up there at 1.1c

111,111

Not sure how long you guys have been around, but if you've ever seen the 1986 movie Wall St, you'll remember a scene where Gecko (Michael Douglas) has his pals contacted with the phrase "Blue horseshoe loves Anacott Steel". 
It was the sign for buying to begin and the next run to start.

Nowadays, many say that the appearance of the above order, is the modern day 'broker to broker' version of the same thing.

To detect its authenticity though, only brokers can see where the order has been placed.
If it's simply a Comsec or Nabtrade trader "trying it on", they can see.

Be interesting to see what happens next, but if a stunning run begins, don't be surprised.
