"CFD | | | Cash | 1398514 | 0.055364"

A CFD (contract for difference) is a financial agreement that lets an investor profit from the change in an asset’s price without actually owning that asset — like betting on a car’s value rising or falling without buying the car. It matters because CFDs use leverage, which can amplify gains and losses and allow easy access to different markets, so they change an investor’s potential return and risk profile and can lead to rapid losses if prices move unfavorably.
