Stop-Loss Slippage: A Worked Crypto Example With Fees Included
A stop fills at the market after it triggers. In fast moves, that fill is worse than the trigger, and the extra loss belongs in your sizing.
Short answer
Stop slippage is the gap between the stop trigger and the average fill. Example: ETH long 2.5 ETH at $3,000, stop $2,940 (planned loss $150 + fees ≈ $7.4). In a fast drop, the stop fills at an average $2,925: an extra $37.50 loss, about 24% more than planned. Measure your typical stop slippage, add it to the loss per unit when sizing, and avoid stops at crowded round numbers.
Worked example
| Step | Value |
|---|---|
| Position | 2.5 ETH at $3,000 |
| Stop trigger | $2,940 |
| Planned loss | $150 + ≈ $7.4 fees |
| Actual avg fill | $2,925 |
| Extra loss | $37.50 |
| Size with $15 slippage allowance | ≈ 2.0 ETH for same total |

Sources and methodology
Arithmetic uses standard sizing formulas. Fee rates (0.05% taker, 0.02% maker), slippage and funding values are illustrative; check your venue's schedule. Liquidation figures are simplified approximations; exchanges calculate them with their own maintenance-margin rules (see Bybit's documentation).
