The only reliable way for us retail investors is to observe whether or not the large volume orders were executed at the bid price or the ask price. Assuming the order is large enough to make a difference and buy order from a retail investor, it will hit the asking price set by the market maker before the securities transaction took place, taking out any prices that were in between. In this case, the MM is on the ask side.
And the reverse is true on a transaction that goes the other way.
Reading through transactions this way is time consuming and only meaningful for large orders and medium to low volume stocks. You will never be able to decipher what is going on with stocks like BAC and C due to their high volume.
