a brief respite?

Looks like the heavy buying has subsided recently.

I wonder if this is a temporary lull or a return to more normal trading volumes?

No recent announcements of change in substantial shareholders or director holdings (at least since Sept). So who has been buying since then?

The next half year report should be very interesting and should (hopefully) give some more indication of just how substantial is the growth in the future order book and the extent of current revenue improvement.
