A Bitcoin derivative liquidation occurs when an exchange's margin rules require it to take over, reduce or close a position. It is different from a voluntary sale of spot Bitcoin. The trigger depends on the contract, margin mode and venue rules.
To understand a liquidation headline, ask which positions were affected, which price triggered the margin test and what the published total actually measures.

A simple leverage example
Imagine a hypothetical linear long position with $10,000 of exposure supported by $1,000 of collateral. A 5% adverse move creates approximately $500 of trading loss before fees and other adjustments.
That example shows why a modest asset move can consume a large share of collateral. It does not calculate the liquidation price. Maintenance margin, fees, funding, margin mode and other balances can alter the threshold. Do not use “10× leverage means liquidation after exactly 10%” as an exchange formula.
| Item | Hypothetical value |
|---|---|
| Exposure | $10,000 |
| Collateral | $1,000 |
| Adverse move | 5% |
| Approximate trading loss before other adjustments | $500 |
For a short position, an upward price move creates losses instead. Position direction matters when reading “long liquidations” and “short liquidations.”
The chart price may not be the trigger price
Bybit's order execution and liquidation FAQ states that its derivatives liquidation uses mark price, while a trader's stop may use last traded price. The two can differ. Other venues and products should be checked individually.
This explains why a chart screenshot alone may not show the relevant threshold being reached. Verify the platform's trigger-price setting and contract documentation before concluding that an execution was wrong.
A stop order and liquidation are separate processes
A stop is a trader's instruction that activates under specified conditions. Liquidation is part of the exchange's margin process. A stop trigger is not a guarantee that the position will close at that exact price.
Our Liquidation Price vs Stop Loss guide explains that distinction. This page focuses on the margin mechanism rather than order-setting instructions.
Why liquidations can accompany rapid moves
Forced position reductions can add buying or selling pressure when available liquidity is limited. Other participants may also change quotes or close risk. The size of the effect depends on the execution process and order book; a cascade is a possible mechanism, not a guaranteed sequence after every liquidation.
Read the liquidity cascade guide for the market-level feedback loop. Keep the original catalyst separate from anything that amplified the move.
Read the reported total carefully
- Check the reporting window and its time zone.
- Check which exchanges, assets and products are included.
- Separate long-position closures from short-position closures.
- Verify whether the figure is liquidated position notional, rather than trader collateral lost.
- Note gaps in provider coverage and the time of the latest update.
A “$100 million liquidation” headline does not by itself prove that traders lost exactly $100 million of collateral. Nor does it establish the next price direction or identify a single cause.
A useful incident summary
Describe the observation window, the provider, affected contracts and the known trigger mechanism. State what remains unverified. If an exchange outage is also reported, distinguish the service incident from the market move rather than assuming one caused the other.
The Crypto Volatility hub links the related explanations. This guide is educational and does not recommend leverage or predict recovery after a liquidation event.
