concern over 18c sell number

Hi all,

The 3.1 mill sell order for 18cents only has 9 sellers compared with, for example, the 18.5c sell order with 34 sellers, which is much more usual. This appears to be a massive sell-off/dump. I hope it's a red herring to appear that way, not someone wanting to offload for a reason?

Any explanations would be appreciated. I don't need any reasons to be nervous now, I've just bought a substantial parcel at 18 cents!

Regards,
Marley.
