The primary difference between CFDs (Contracts for Difference) and NASDAQ contracts lies in their structure and trading mechanisms. CFDs are derivative instruments that allow traders to speculate on the price movements of an underlying asset without owning the asset itself. On the other hand, NASDAQ contracts typically refer to actual stocks listed on the NASDAQ exchange. When you buy NASDAQ stocks, you own a share of the company. Additionally, orders for CFDs are typically executed over-the-counter (OTC), while NASDAQ stocks are traded on the exchange. 

It is also important to note that CFD trading may not be available in your broker or in your region. We recommend contacting customer support for relevant info on trading conditions.
