What is a CFD?
A contract for difference lets you trade the price movement of an asset without owning it. You profit or lose based on the difference between the opening and closing price.
Leverage and margin
Leverage lets you open a larger position with a smaller deposit, called margin. It increases both potential gains and potential losses.
Bid, ask and spread
The bid is the price you can sell at, the ask is the price you can buy at. The difference between them is the spread.
Stop loss and take profit
A stop loss closes a position automatically to limit losses; a take profit closes it once your target is reached.
Margin level
Equity divided by used margin. If it falls too low, positions may be closed automatically to protect your account.
Managing risk
Size positions sensibly, always use a stop loss, and never risk money you cannot afford to lose.
