The executed price will depend on the Buyers demand right now the pre-open is @.42c

Buyers keep bidding up to make sure their order gets executed on open and on the sellers side as long as that sell is below the pre-open sp then their sell order will go through...

You can usually see the pre-open price if u have a live platform, on Comsec & am sure lots of other trading platform - I have Etrade their website doesn't show pre-open but their live platform does
