Of course TD does not have a problem with this type of trade as they do not wish to implicate themselves in any "shady" trading scheme. Only a fool or a manipulator would place this type of "uneconomic" trade as the commissions are too great a percentage of the price of trading. As such, one can only logically reason that manipulation is the game.
That assumption would have been made by very qualified professionals. So I have to wonder why so many posters here think it is so odd that regular folk like me question such trading patterns.
