What is crypto liquidation and how do I avoid it?

Leverage lets traders control a position that is larger than the margin they commit. That can increase capital efficiency, but it also leaves less room for the market to move against the position. If losses reduce the available margin below the amount required to keep the trade open, the exchange may begin closing the position. This process is called liquidation.

Liquidation is not simply a losing trade. It is a risk-control process that starts when a position or account can no longer meet its maintenance margin requirement. Understanding the trigger, the price used by the exchange and the effect of each margin mode can help traders act before the liquidation engine takes over.

Key takeaways:

• Crypto liquidation is the forced reduction or closure of a leveraged position when its margin can no longer meet the maintenance margin requirement.

• On Bybit, liquidation is triggered by Mark Price. The exact process depends on whether the account uses Isolated, Cross or Portfolio Margin.

• Traders can lower liquidation risk by using less leverage, limiting position size, monitoring margin and placing an exit before the liquidation level.

What is crypto liquidation?

Crypto liquidation occurs when an exchange forcibly reduces or closes a leveraged position because the supporting margin is no longer sufficient. The exchange does this to prevent the position from creating a loss that exceeds the funds available to cover it.

Every leveraged position requires maintenance margin. This is the minimum amount of margin that must remain available for the position or account to stay open. If an adverse market move pushes the margin below that requirement, liquidation may begin.

The basic relationship is straightforward:

• A long position loses value when the market falls.

• A short position loses value when the market rises.

• Higher leverage commits less initial margin relative to the position size, so a smaller adverse move can bring the trade closer to liquidation.

Leverage itself does not create the loss. Position size and price movement determine the profit or loss. Leverage changes how much margin supports that exposure. This is why overleveraging can lead to liquidation even when the underlying price move appears modest.

How does liquidation work on Bybit?

Bybit's Unified Trading Account supports Isolated Margin, Cross Margin and Portfolio Margin. The liquidation trigger and the funds available to support a position depend on the selected mode.

Liquidation under Isolated Margin

In Isolated Margin mode, each position has its own allocated margin. Liquidation is triggered when Mark Price reaches that position's liquidation price. The liquidation of one isolated position does not directly use the margin assigned to another isolated position.

Before closing a position, Bybit uses a laddered process. The system first cancels active orders that would increase the position size. If the position is above the lowest risk-limit tier, it may attempt to reduce the tier through a partial close. If the remaining margin is still insufficient, the position is closed at its bankruptcy price.

This separation can make the maximum amount assigned to a trade easier to control. It also means unused funds outside the isolated position do not automatically rescue it unless the trader adds margin or enables a relevant margin-management feature.

Liquidation under Cross Margin

In Cross Margin mode, available margin in the Unified Trading Account is shared across positions and orders. Account risk is measured through the Account Initial Margin Rate and Account Maintenance Margin Rate.

When the Account Maintenance Margin Rate reaches 100%, Bybit starts reducing risk. The process can include canceling orders that increase exposure, repaying liabilities, canceling remaining orders, closing fully hedged positions and liquidating unhedged positions. If necessary, short Options positions may also be liquidated.

Because margin is shared, a loss in one position can reduce the cushion supporting other positions. The displayed liquidation price is dynamic and can change with account equity, unrealized profit and loss, open positions, maintenance margin and available margin.

Liquidation under Portfolio Margin

Portfolio Margin also uses an account-level Maintenance Margin Rate. It estimates the risk of eligible positions as a combined portfolio through stress testing. Offsetting exposure may reduce the margin requirement, while concentrated or directional exposure may increase it.

Liquidation begins when the account Maintenance Margin Rate reaches the applicable threshold. Because risk is calculated across the portfolio, derivatives positions do not have a standalone liquidation price in the same way as an isolated position. Traders need to monitor the account's risk metrics and how each position changes the combined exposure.

What price triggers liquidation?

Bybit uses Mark Price to trigger liquidation for derivatives positions. Mark Price is designed to reflect a fair reference value and reduce the effect of temporary price spikes or abnormal trades in the Last Traded Price.

This distinction matters because the default candlestick chart may display Last Traded Price. A trader can therefore see candles that appear to remain away from the liquidation price while Mark Price has already reached the trigger. Traders should display or monitor Mark Price when managing a leveraged position.

A stop-loss order and liquidation can also use different trigger settings. If a trader chooses Last Traded Price for a stop while liquidation is based on Mark Price, Mark Price may reach the liquidation level before the stop is triggered. The trigger type should be chosen deliberately rather than left unchecked.

Liquidation price vs. bankruptcy price

Liquidation price and bankruptcy price describe different stages of risk.

• Liquidation price is the estimated price at which the position or account reaches its maintenance margin requirement and the liquidation process begins.

• Bankruptcy price is the point at which the position's losses consume the margin allocated to it. For a perpetual position taken over by the liquidation engine, this is the price at which the margin balance would fall to zero.

The displayed liquidation price should be treated as an estimate, particularly in Cross Margin. Trading fees, funding fees, added or removed margin, other positions and changes in the maintenance margin requirement can move the actual level.

What causes crypto liquidation?

Using too much leverage

High leverage creates a narrow margin buffer. For example, a 20x position uses initial margin equal to roughly 5% of its notional value before fees and other requirements. A move of about 5% against the position can consume that initial margin, although the actual liquidation point also depends on maintenance margin, fees and the contract setup.

Traders can review how leverage works in crypto trading before selecting a multiplier.

Opening a position that is too large

Low leverage does not make an oversized trade safe. A large position can still create a loss that is too large for the account. Position size should be based on the amount the trader is prepared to lose at the planned exit, not only on the maximum size the platform permits.

Letting losses run without an exit plan

Liquidation becomes more likely when a trader waits for the exchange to close the trade. A planned stop can close the position while some margin remains. Without one, a fast market move can erase the available buffer before the trader reacts.

Ignoring other positions and liabilities

Under Cross and Portfolio Margin, positions share account-level risk. A new order, a loss elsewhere or a borrowed-asset liability can raise the Maintenance Margin Rate and move liquidation closer. Looking at one position in isolation may give an incomplete picture.

Funding fees and trading costs

Funding fees, closing fees and other costs can reduce available margin. Their effect is more serious when the account already has a small buffer. If the available balance is exhausted, further deductions may come from position margin and move the liquidation price closer to Mark Price.

Sudden volatility and poor liquidity

Crypto markets can move quickly, especially around major announcements or periods of thin liquidity. A stop order can experience slippage, and an exit may fill at a worse price than expected. Risk controls reduce exposure, but they cannot guarantee execution at the selected price.

What happens during liquidation?

The exact sequence depends on the margin mode, risk tier and products in the account. Bybit generally attempts to reduce risk before completing a full liquidation.

For an isolated derivatives position, this can mean canceling orders that would add exposure, lowering the risk tier through a partial close and closing the remaining position if it still cannot meet maintenance margin.

For a Cross Margin account, the system may cancel exposure-increasing orders, repay liabilities, cancel all orders and reduce open positions until the Maintenance Margin Rate falls below the trigger. If the Account Maintenance Margin Rate reaches 160% or more, the liquidation engine may take over the entire position, excluding bought Options under the current rules.

Liquidation may also involve fees and execution through the order book or other liquidity arrangements. Traders should not assume the final result will equal the liquidation price shown before the event.

How to avoid crypto liquidation

No method can remove market risk, but traders can increase the distance between normal price movement and forced closure.

Use lower leverage

Lower leverage requires more margin for the same position size and usually creates more room before liquidation. It also reduces the temptation to open exposure far larger than the account can support.

Choosing 5x instead of 20x does not guarantee safety. The position still needs a suitable size and exit plan. The benefit is a wider margin buffer for the same notional exposure.

Size the position from the stop-loss level

Start with the amount you are prepared to lose, then calculate the position size using the distance between the entry and the stop. This ties risk to a planned exit rather than the exchange's maximum leverage.

For example, if a trader is prepared to risk 100 USDT and the stop is 2% from entry, a simplified position-size estimate is 5,000 USDT before fees and slippage. Leverage changes the initial margin required, but it should not change the 100 USDT risk limit.

Place a stop before the liquidation price

A stop-loss order should normally sit far enough from the liquidation level to close the trade while margin remains. Check whether the stop is triggered by Mark Price, Last Traded Price or Index Price and choose the setting that matches the strategy.

Stops are not guaranteed at an exact execution price. During a rapid move, the order may fill with slippage. A stop placed extremely close to liquidation may also fail to provide a useful buffer.

Monitor Mark Price and margin metrics

Do not rely only on the main candlestick chart. Track Mark Price, liquidation price, available balance, Account Initial Margin Rate and Account Maintenance Margin Rate as relevant to the selected mode.

Set alerts before the account reaches a critical level. Early warnings give the trader time to reduce a position, close another trade or add margin without making a rushed decision.

Add margin carefully

Adding margin to an isolated position can move its liquidation price farther from the market. It does not improve the quality of the trade or reduce the position's notional exposure. Adding funds repeatedly to avoid accepting a planned loss can increase the total amount at risk.

Under Cross Margin, depositing collateral may improve the account buffer, but all positions can draw on the shared funds. The trader should review the whole account before adding capital.

Reduce or partially close the position

Reducing position size lowers exposure and may release margin. This is often more direct than adding collateral because it reduces both the potential loss from another adverse move and the margin required to maintain the trade.

Choose the margin mode deliberately

Isolated Margin limits a position to its assigned margin but offers less automatic support from the rest of the account. Cross Margin shares available funds, which can prevent one position from being liquidated as early but can expose more of the account. Portfolio Margin may suit experienced traders with offsetting positions, but its account-level risk is more complex.

The right choice depends on the strategy. Margin mode should be selected before opening the trade, not after risk has already become difficult to manage.

Keep an account-level risk limit

Set limits for total open exposure, maximum loss per trade and maximum daily loss. Multiple individually reasonable trades can combine into a highly directional portfolio. A simple account-level cap helps prevent several correlated positions from reaching liquidation together.

This crypto trading risk management guide explains how position sizing, stop losses and diversification fit into a wider plan.

A simple liquidation-risk checklist

Before opening a leveraged position, check the following:

1. How much of the account will be lost if the stop is reached?

2. Which price type triggers the stop and which price triggers liquidation?

3. How far is the planned stop from the estimated liquidation level?

4. Is the position using Isolated, Cross or Portfolio Margin?

5. Could another position, liability or funding payment reduce the margin buffer?

6. Is there enough room for normal volatility and possible slippage?

7. What action will be taken if the trade moves against the original idea?

If these questions do not have clear answers, the position may be too large or too highly leveraged.

The bottom line

Crypto liquidation is the forced reduction or closure of a leveraged position when the supporting margin can no longer meet the maintenance requirement. On Bybit, Mark Price is the key liquidation trigger, while margin mode determines whether risk is measured at the position or account level.

Avoiding liquidation starts before entry. Use leverage that leaves room for volatility, size the trade from a defined loss limit and place an exit before the liquidation level. Continue monitoring Mark Price and account margin after the trade opens because fees, liabilities and other positions can change the available buffer.

Liquidation should be treated as an emergency mechanism rather than a normal exit strategy. A trader who waits for the liquidation engine has already surrendered control over when and how the position closes.
