I received a reply from the tse..... regarding the not listing of all the FEN trades.
Basically the tsx or tsx venture show only what
was traded on their exchange. Brokers have
the discreation to send clients order to market
place as long as best execuction guidelines
are met. Orders can be sent directly to ALPH
and other alternative trading systems (ATS) in
Canada that are regulated by IIROC as well as
TMX group exchange.
