My pending order did not open at the price in which I selected, why?

FXCM takes the required steps to ensure that trades are executed at the quoted price with the best possible result for our clients. Due to fast moving markets, transaction executions may occasionally be at a price that is no longer the best market price. This is known as slippage. FXCM provides a number of ways to help clients reduce execution risk. One way may be using a tool called Market Range. This allows traders to specify the amount of slippage allowed by defining a specific, individually acceptable range. An FXCM client has the ability to change this value to 0 to ensure that no slippage is permitted. The order is either opened at the predefined price or not executed at all.
