Re Quote

It determines the value that is changed between the time of sending the order by a trader and attempt of a broker to execute it. This means that the time differs from a period the order was to a period it reached the broker. The trader can either accept the possibility that the worse price is appeared or cancel the order with the aim of making next orders that can be better than the previous one. Such situation can happen with brokers according to the fast changes and fluctuations of the Forex market conditions.
