hoping i could find some info here, but no chats. So trying to work out what happen i received special dividend sold SYM and bought ABB today. The only issue i have i used Superhero for trading and it showing i purchased Aussie Broadband for $5.7235 with no brokerage fee at around 2.30pm. .The issue i have is they never went that high and could not see any info in relation to price in announcements. I sold Symbio for $3.01 and received 0.35c per share divy.
