This direction is chosen by convention. Actually when the concept of current came to be discovered by physicists, they did not know about the negatively charged electrons and hence they thought that current must flow in the direction of positively charged protons. So, even after the discovery of electrons, scientists refused to change the convention due to some reasons. Hence it is shown that current moves form + to - in the direction of conventional current (flow of protons).
