I am confused about two things I see on the online charts for the NZX market:

1. Often when looking at the online charts for the day's trading on the NZX website or on the ASB Securities website, I see that the last traded price doesn't match the price shown at the end of the day on the daily chart. For example, looking at MCY for today (https://www.asb.co.nz/asb-securities...e-mcy-nzx.html), the "last traded price" is $3.35, but the chart shows the daily trading closing at $3.28. In fact, nowhere on the daily chart is there any trade at $3.35 - the trades started at $3.32 and fell to $3.28.

2. The daily volumes often don't match up on the NZX website and the ASB Securities website. Well, they always seem to match for the current day, but often the volume for a particular day drops subsequently on the NZX website, while it remains the same on the ASB Securities website, so they end up with a large discrepency. For example ASB Securities is showing the volume for SAN yesterday as over 2.7 million, while the NZX site is showing it as 3764 - a HUGE difference.

Can anyone explain to me what is happening in either of these cases? I feel as if I am not seeing the full picture.
