Abstract

Methods, systems, and computer readable media for facilitating trading two items (L,Q) from the group of items comprising commodities and financial instruments. At least two agents (2) want to trade the items (L,Q). There is a trading channel (3) between the two agents (2) allowing for the execution of trades. There are flow (trading) limits on the items being traded. A central computer (1) is coupled to the two agents (2). Said computer (1) is adapted to convey to each agent (2) current tradable bid and offered prices and sizes subject to the agent'"'"'s (2) trading limits.
