Panamax,

You are right.TD has always been an active participant in HFT wracking havocs all over the stock exchanges.I believe they were also one of the defendants in the LIBOR scandal and lost the case.

Although defendants of the HFT trade always stated that they help contribute to the liquidities of the market.But the truth is that this activities help no one but for the manipulators to flush out the bids and asks for their advantage.If they were made to pay for every trade that they ordered but failed to carry out(almost 90% of them),that will be true liquidities to the stock exchanges.Some European countries had banned and restricted the use of HFT altogether.I think the canadian OSC are asleep at the switch and refused to wake up.
