Does anyone have access to the broker data for this last few days trading? Tuesday's trading was odd, then yesterday things got weird, and today was the beginning of something new for Nexus. And it all aligns with multiple brokers/advisors being onsite this week. Why are they all there now? And why did the CHIX:ASX ratio (chix competes with asx by matching trades within shared brokers to provide cheaper trading fees) drop from the normal average of around 1/5-1/3, to todays 1/13th? Brokers seemed to have had quite strong and consistent recommendations for their clients today, because they were only buying from clients of other brokerage firms...

So, I'm curious to see the broker data...
