Not trying to be a smart alec, but what is your end goal here?...

Not trying to be a smart alec, but what is your end goal here? What are you trying to get to the bottom of and once you have, what are you hoping to happen? If it is simply identifying someone who is selling down the stock and calling them out, fair enough, but is that all you are trying to do?

Do not get me wrong, I am now in a 4 week battle with ANZ/Financial Ombudsman/ASIC in regards to the ANZ Share Investing platform. I reckon I have ANZ now on toast given a recent response but my end goal is:
1. to claim compensation through the Ombudsman
2. To have ANZ Shareinvesting modify their trading platform for small caps

What is your ultimate goal? I reckon it is imperative there are people out there like you and me who investigate and push these matters. Just hoping the time you have put into this will mean you will get something in return.
