Pictured in the photo I purchased above (no photographer credited) is the old CBOT financial room which is also the original trading room at the CBOT. When the grains moved to their current trading floor in 1982, the financials were able to occupy the entire room and remained trading there until the construction of the new CBOT financial floor in 1997. After the move to the new floor in 1997, this room became occupied by the Mid American Exchange (MidAm) and after the
MidAm was closed in 2001, it was leased out as it currently is today by options trading firm
Peak6 and the room is prominently displayed on the homepage of their website. As usual, click on the photo to enlarge for detail.
