Curiosity got the better of me and i had a look at what you were talking about. I've never even heard of this company, while it does look like 12 million, it's actually 12 THOUSAND, just they put an extra zero on the cents column, which gives it the appearance of 12 million. But i think they are ghost trades, as on the IRESS platform, that shows as NIL TRADES today
