Definition: Intertrading is a type of financial market where two or more parties engage in trading activities on an exchange. This means that there are multiple investors who participate in the same transaction, and each party has their own account to track their position. In intertrading, traders often use various forms of securities such as stocks, bonds, options, and commodities. They may also trade futures or swaps, which are financial instruments that are bought or sold based on future prices rather than a fixed amount of money
