Here's G1A broker data from 7 Sep 2018 - 29 Oct 2018 (latest available to me).
As you can see, there has been some very heavy selling from Pershing and ITG Australia. I believe there must be some big holders exiting. This was also IMO the reason the share price hasn't been able to break out. The good news, however, is that there has also been very big buying from some "smart money" (Instinet / Nomura and Hartleys).
Anybody wants to take a guess of who in the top 20 (see below, as of 6 Sep 2018), that are clients of Pershing and ITG, responsible for the selling? Regardless, I think they should be running out of ammo soon (if not already) after offloading ~7 million shares (i.e. the total between Pershing and ITG). The share price can rocket then.
