Actually, there is generally nothing like the best trade in engineering. If you mean the popular engineering branches, in most universities they are computer science, mechanical, electrical, civil, Electronics and Communication. However, ideally this should never be the basis for decision making. What interests you in engineering should be the ideal choice rather than what others take up. That will allow you to shine in what you like.
