asx unfair and misleading practices, page-2

Section 18 of the Australian Consumer Law
'A person must not, in trade or commerce, engage in conduct that is misleading or deceptive or is likely to mislead or deceive'.

In other words, the one party can not provide information that is deliberately trying to mislead and deceive a consumer.

What you have here has nothing to do with being misleading or deception, but it is instead a disparity of a policy of rounding by 2 completely unrelated entities. The only response I would expect you will receive from ASIC is to refer to the terms of use of the information provider.

In relation to the trading by brokers, brokers are able to trade at two different price points but all that is being recored is the average price (the mid point) for settlement purposes. What this does mean is if you are seeing a trade of 10 shares at 0.075 then there has actually been a broker transaction of 10 @ 0.007 and 10 @ 0.008.

This may be used to their advantge to show unusual movements in the share price but that would be hard to prove unless you were an insider to the broker.
