Trade-lista is a list that advocates for the interests of all bba students at Haaga-Helia. The goal of the list is to bring more club activities and easily accessible initiatives, providing more valuable Helga membership and making Helga more student-oriented and approachable. Trade-lista has been created in collaboration with Talko, Atkins, Hsoy, HePo, and Sture.

In the Helga Representative Council, decisions are made regarding tutoring, club activities, events, and how Helga's activities are visible within and outside the school. Every Helga member has the opportunity to influence these matters by voting.

​

In the year 2023, Trade-lista has gotten thirteen out of twenty representative posts.
