RE:RE:GENM TSX April 20 I assume they showed up in your account. If so it probably was filled on one of the small exchanges - but that's a guess on my part.
I use a quote system that allows me to see previous trades on a delay basis and gives me trading volumes on an exchange by exchange basis at the end of the day but I don't think that's always true (many just show Toronto).
It makes it hard for smaller investors to know how to place orders. As an example I bought 35,000 shares of another stock today but only 6,000 were showing on the offer. I didn't know whether I might have to go up to get a complete fill and I almost decided to wait until enough were showing (and might have missed it) so I took a chance, placed the order and got the fill without having to go up. The stock was available but it simply didn't show.
These smaller exchanges are good for the brokers (they charge less to process trades but the lower cost isn't passed on to the public) but are another complication for the investing public.
