Last Trade: 1 only 13cent trade

What does every one make of the last trade showing up as one trade
I spoke to ASIC and that really can't say and the info is confidential of who made the trade.

If everyone were to through in a few bob for a class action we made be able to find out if the trade is effected trading and trading at 13.7cents and not as per limited on Etrade,Westpac online, Nabshare, Commshare i.e. 13.5cents or 14 cents. I.E the level playing field

The other point why do some broker not show the full trade volumes like etrade, is this an issue, as we are paying for full info not glass half full

I believe ASIC and other could be including I a class action if the two issues are effecting small traders
What is everyone’s thoughts
