Some would liken that to a temporary roadblock - conditions change and it's quickly removed. Still interesting given sentiment definitely seems to be shifting to buy why it's there? Either trying to cap the price under 20c, or a recent larger buyer under 19c (on asx or through previous raise at 17c) looking for a quickish profit without initiating to much sell pressure which would then make it difficult for them to offload the volume they have. Either way can be viewed as positive. Perhaps whoever is selling is not comfortable with the risk/reward profile for the last RAP/finance hurdle? A bird in the hand i.e. smaller % gain guaranteed is better than 2 in the bush i.e. possibly higher % gain on positive RAP/finance, or possible loss in the next few weeks. Selling is 100% fine if your not comfortable. That aside they are doing it in a way so as to not encourage other selling, while ensuring the price doesn't appear capped and so volume appears less on a daily trade history. Hypothetically an iceberg sell at 19c with a buy at anything under 19c makes you money...
Iceberg or not, 64 buyers for 3mil shares vs 22 seller for 800k is also saying something.
