The same thing happened last week when a buyer took one share at the ask price in many small cap companies.

This week it seems to be the other way round in many of the same companies, with one share being traded at the bid price.

Looks like market manipulation to me. Perhaps designed to distort the statistics for TA, to encourage people to buy or sell depending on what the chart shows.

I would have thought that the ASX or ASIC would have noticed these trades if it is so obvious to us amateurs.
