There is a problem to move potential sellers down especially in some potentially great news expectation. trust me it requires a real art from traders to push price down on such expectations - there is set of technics (especially if you have enough in your portfolio to buy and sell to yourself). I think TD traders are goof enough to play it for some time.

The biggest question is HOW BIG is an order from client (doesn't metter internal or external). If they need to fill in about 5-10 mln, the situation will be developed the following way - the price will stay for a week and afte rnews TD will help to push the price up with a small client funds leftover.
