Blackboard Trading The trading of commodities and futures contracts off a blackboard found on the wall of a commodity exchange. Investopedia Says: Not all commodity- and futures-contract transactions occur electronically. On some smaller exchanges or on certain contracts where the volume of trade is relatively small, blackboard trading is a cheaper and logical alternative to electronic trading.
