The information that you see is from the TSX.V. Shares are also traded on Alpha and those do not show up on most systems including Agoracom. I got a bit of a surprise lately when my order was filled. I had placed an order at the ask price and was filled at .005 less. Same as what you are saying, they did not appear in the TSX.V volume or pricing information.....they were filled from Alpha.
It is a lousy system and I personally don't think it should be allowed because we don't always see accurate information, especially total volume.
