Slippage
The Formal Definition
The difference between the expected execution price of an order and the actual price at which the trade is executed.
Slippage = Executed Price - Expected Trigger Price
Cole Barrett's Reality Check
The Unvarnished Bottom Line"Slippage is the ghost tax of active trading. You hit buy at $50.00, your order gets filled at $50.08, and you never even realize you just paid an 8-cent commission to a high-frequency trading firm."
