What is Slippage
The difference between the price you expected and the fill price. It happens with market and stop orders — more often in fast moves and thin books.
How it works
BTC 1m, 15.05.2024 12:30 UTC — US inflation release: a minute 25× longer than usual.
Example
The 12:30 minute covered 1 082 $ — from 62 662 to 63 744. A market or stop-market order in a minute like that fills against a thinning book: the average price can drift tens of dollars from the screen price.
Common mistake
Not logging the actual exit price: then the R in your journal is better than reality.
