I think it's the bottom too.
Can it fall further from here? Possible, but it can also shoot up on an announcement release.
Anyone trying to put a bid at 1.6c tomorrow, my guess is that it probably won't get hit with 12.6 million buy depth sitting there already.
If you want to buy in (or buy more) before the next announcement, you should (IMO) be putting in your buy at 1.7c.
DYOR.
