Slippage

Slippage is the result of a difference between the expected price of the trade and the acquired price at the time of execution. On a high liquidity market, a slippage usually occurs as a result of a sudden swing in price. A slippage occurs if the price of the EUR/USD is at 1.2022 the moment the buy button is clicked and the posted final price that the trader receives is at 1.2085.
