Does the electric field only move in the + ---> - direction? Or does it depend on the charge, so that the electric field moves in a + ---> - direction for a + charge and moves in the - ---> + direction for a - charge?

In the latter case, if a + charge is moving toward the - plate of a capacitor, is its direction negative since it's moving toward the negative, or is its direction positive, since it's moving with the electric field?
