The Market Profile graphic was introduced to the public in 1985 as a part of a CBOT product, the CBOT Market Profile (CBOTMP1) (2). CBOTMP1 included the new Liquidity Data Bank (LDB) data; end-of-day clearings, all trade was categorized and identified by the class of trader in the pits ( (1) local, (2) commercial, (3) members filling for other members and (4) members filling orders for the public). The Profile was proposed as a visual organizing methodology in addition to these new data.
