If you hold a forex spot CFD position “overnight” you may pay a Rollover charge or be paid a rollover benefit by your CFD provider. It is important to know at what time this “overnight” rollover charge occurs for your timezone.
Compared to the specificity of trading with spot forex, trading currency index CFDs allows the trader to take a general view. This is because the underlying reference is actually a weighted basket of currencies. The weightings are chosen and determined by your CFD broker.
When you trade a Spot Forex, you, as a trader, take a position on the foreign exchange rate of one currency against another (For example, USD/JPY, EUR/USD or AUD/USD). Therefore, when trading with a spot forex CFD you are trading the CFD which has a currency exchange rate as the Underlying Reference Security.
