Losses can exceed deposits

### Got any questions?

The best way to understand how CFDs work is to follow some examples.

Assume you want to buy 1000 Vodafone CFDs and the exchange price stands at 249.9-250.0p. Your CFD position will be opened at the upper price of 250.0p. The full contract value of this position is 1000 x 250.0p or £2500, but to open the contract you need only put down a margin deposit.

Your margin requirement will be 4% of the full contract value, which is £100, although you can reduce this margin by attaching a stop-loss to your position. Your commission to open this position will be 0.1% of your total position value. This comes to 0.1% x £2500 = £2.50, paid on opening.

Suppose a fortnight later Vodafone shares have risen steadily and the market price now stands at 268.3-268.4p. You can now close your CFD position by selling at the bid price of 268.3p. Your commission to close this position will be 0.1% x £2683 = £2.68.

BUY price 250.0 268.3 18.3p 1000 £183

### CFD Example: Selling Wall Street

Suppose you want to go short of Wall Street. Our quote for the cash index has a 1-point dealing spread and might be 17463-17464. This means that you can sell at 17463, the lower end of our quote. One CFD contract on Wall Street is worth \$1 per index point. You want to risk \$3 per point so you sell three CFD contracts at 17463.

Your margin requirement to open this position will be 0.5% of your position value. This comes to \$3 x 17463 x 0.5% =\$261.95 (converted into your account currency). You can reduce this margin by attaching a stop-loss to your position. For example, if you attach a stop 10 points from your opening price, your margin requirement will be (\$261.95 x 50%) + (\$3 x 10) = \$160.98. There is no commission to pay as all the charge is included in the dealing spread.

SELL price 17463 17339 124 points \$3 \$372
