RE:Today's volume, for the math-unable You are indeed incorrect and have posted misinformation.
The volume on Canadian exchanges was not around 500,000 but rather about half of that.
And the observation was made based on likely a delayed quote from only the TSX main board around 1 PM.
A word of friendly advice, when you accuse someone of effectively deliberately posting misinformation, you should make sure you know what you are talking about. Otherwise you risk the appearance of doing so yourself.
