In forex, there are two types of spread brokers: fixed and variable. A fixed spread means the spread is fixed regardless of the market condition. However, the disadvantage of fixed-spread brokers is often requoting. While the variable spread is spread, the number depends on the market. The ECN broker uses variable spread; here, no requote problem occurs; all orders are forwarded to the market instantly. It is possible to get a zero spread on an ECN broker. FXOpen is an ECN broker offering a low spread of 0.0 pips and zero commission on index CFDs. Using the TickTrader terminal makes it possible to get negative spreads on pairs like EURUSD, USDJPY, AUDUSD, and more.
