CFDs are derivative securities, their price is derived from the price of the underlying instrument in which the CFDs refer to. Derivative securities/markets can be highly volatile. The prices of CFDs, the underlying instrument and indices may fluctuate rapidly, in a wide range and may reflect unforeseeable events, or changes in conditions, none of which can be controlled by the Client, or the Company. Under certain market conditions it can be impossible for a Client's order to be executed at a declared price.
