Why did the ann come out at lunchtime in the eastern states when most interested parties would have been occupied with their sangers, sushi rolls or three chardie lunches?

Why then for such a sensitive ann that time wasn't given for the market to digest it (poor pun for lunchtime) before trading commenced?

45 Million went through in 15 minutes before anyone had returned to their screens.

And I noticed once again the same last 3 digit sellers/buyers were immediately in action.

I nearly choked on my pie and sauce when I returned to the screen just prior to 2pm. Anyone else feel they were caught out?
