Quarterly CFDs refer to contracts for difference that expire every quarter, typically at the end of March, June, September, and December. These contracts are derivatives that allow traders to speculate on the price movements of underlying assets, such as stocks, commodities, or currencies, without actually owning them. Quarterly CFDs are popular among traders who prefer a longer-term approach to trading and want to avoid the rollover fees associated with daily or weekly CFDs. However, since they have a longer expiration period, quarterly CFDs may also expose traders to greater risks and require a higher level of capital.
