That is my understanding, from what I've read of some posts on here from people who appear to be pretty well connected in the investment world.  I'm not sure if that is only outfits like Pinetree and Sprott (or Cormark) who handle their investors trades and place stops for them and keep track of that, or if it also includes other brokers.  Maybe Rosedale will be available sometime to speak to this, or perhaps someone else who works (or has worked with brokerages) can speak to this?
