Help understanding current direction with transistor?
"Conventional Current", used by most scientists, engineers and technicians, is a flow of positive charges, from the positive terminal of the battery, through the external circuit, and returning to the negative terminal of the battery.  The arrow in transistor and diode symbols (except Zener diodes) points in the direction of conventional current flow.

You apparently are used to electron (negative) current - this concept was apparently introduced to teach technicians how vacuum tubes work, as it is very difficult to explain vacuum tube operation using conventional current.  You should try to get used to using conventional current, as most people use that concept.

The circuit in your question is drawn in a very confusing manner - try re-drawing it with the most positive voltage at the top, and most negative at the bottom of the drawing - it may make more sense drawn that way.
