If you believe that the share-price will rise over the next 3 months, you would “buy” at 503.0. You need to decide your stake and then, click on the Trade button. For this example, lets say you choose a stake of £2 per penny movement.
This means that you will receive £2 for every penny the share price rises. If the share Capital Spreads quote for Barclays rises to 511.0-513.5 you may decide you want to close your position to realise the profit.
A sell bet always closes a buy bet, and vice versa. Alternatively, you can leave the bet to expire in March, when your bet will be automatically closed.
If, however, the share value falls and you do not sell to close, your bet will close if it reaches your CGSL or Stop-Loss level of your choice, ensuring that you do not incur excessive losses.
The previous example shows that you opened your bet at 503p and that when the market fell, the trade was automatically closed by a Computer Generated Stop-Loss (CGSL) at 453p. The maximum loss on this bet was £100 (503.0 – 453 x £2 = £100).
As the graph shows, the share price continued to fall, whilst the Stop-Loss ensured that further losses were not generated.
