The adjusted price is called just adjusted price. Usually you get the adjusted close and then adjust the other price components. It is the case for data from "Yahoo" for example.

And if I feeds two data, I have to align them in advance according to datetime right? Is there such a solution in backtrader?
The engine will synchronize them. But if one is the raw price and the other is the adjusted price, it would a surprise if they don't carry the same timestamp.
