A CFD is a sort of financial derivative that enables traders to speculate on the price of various financial asset classes including forex, shares, indices, futures, metals or commodities.
When trading CFDs, traders don’t actually own the underlying instrument but rather only trade price movements, both rising or falling, over a short time period.
You can open a CFD position by choosing the number of contracts, also known as trade size, that you want to purchase or sell. With each point the market moves in your favour, your profit will increase accordingly. However, if the market goes against you, you might take a loss.
In other words, CFDs operate by imitating the underlying market. Therefore, in addition to mimicking a typical trade that generates revenue when a market price increases, you may also establish a CFD position that generates revenue when the underlying market price declines.
