Hi Knowlesi
I'm hoping not to end up looking stupid in trying to answer your question about the MM's (tree shake) but I'll put my opinion forward.
The MM's don't just match buys with sells they are the Market Makers and use the spread and adjustments in the price to encourage trading, no doubt the odd trade goes through, 'tactically adjusted' even though it shouldn't.
But we are all grown ups here, so we know it probably happens.
If someone wanted to buy a large amount of shares and pre-agreed a price its up to the MM's to gather those shares at the lowest possible cost price, so by using all of their various 'skills' they induce trades, which I think is what is commonly know as "a tree shake".
Hope that helps.
