Does anyone know if one can download the course of sales on CommSec for a particular date/ date range? Alternatively, if there is another open web service that lets you do the same? Apologies in advance if this is a noob question. I did try to look around in CommSec to find this info.

The reason I ask is, around 12pm yesterday, when the volume was already around 50mn (~$20mn), bulk of the trades were over 53c. I would like to determine the average weighted traded price yesterday. I have a strong feeling that this was a shake-the-tree exercise, which later turned into profit-taking (fair enough!).

Thanks
