The Alkek Library and the 4th Floor Computer Lab are proud to have a Bloomberg Terminal available for use. It is located just outside the glass wall lab, and you do have to sign in to use it. It is first come, first serve.
Bloomberg terminals are dual screen, professional grade trading platforms. Many brokerages ask for new hires to be proficient in their use. They are notoriously expensive, and you are not getting access to one in your private life (well, probably.)
And no yelling BUY and SELL in the work area!
