Trading in contracts for difference, frequently referred to as CFDs, is becoming increasingly popular among both institutional and private traders because of the flexibility they offer. CFD trading is a speculative instrument for trading shares, indices, futures and commodities. It is a retail-level market derivative utilised by traders for its leverage advantages. CFDs are also known as equity swaps in the institutional marketplace.
A CFD is an arrangement made in a futures contract whereby differences in settlement are made through cash payments, rather than the delivery of physical goods or securities. (Investopedia)
