BBOZ, page-9

I have a novice question regarding BBOZ. Clearly, the fund is a synthetic holding and is rebalanced daily after the market closes. When I place a buy or sell order, am I effectively competing for units against traders/holders at that specific moment? If I purchase 'at market,' does this mean I am essentially paying a premium to traders to secure a position? Hypothetically, considering the below-market depth, if I were to acquire all 2.1 million available units today, how would Betashares react? Or would my actions merely drive up the price of the units in the market at that time, even though, as an ETF, the price at any given moment should reflect the fund's objective?
