Thank you for those comments, marcos.
Yes, not being able to put limit orders on the small stocks is the primary reason I have bought more stocks that are listed in the US. Also, when I buy Canadian stocks that have a corresponding pink sheet symbol, it seems the market maker takes a bigger cut.
Greystar is just a gamble that I will put away for now. I loved that article you referenced! ;-)
