Practical use
How to verify Slippage
Read Slippage together with Strike distance, Barrier, Barrier distance. The comparison must preserve the exact rule, value, state, and evidence described below.
A neutral example
Exported Slippage history omits the pre-trade quote. A contemporaneous ticket capture is paired with result rather than inferring Strike distance. The result is classified under Slippage because expected and accepted levels differ only after quote side, timestamp, and server acceptance are aligned.
