Every leveraged trader encounters liquidation eventually — either by experiencing it firsthand or by watching it wipe out someone else's account. It's the mechanism that makes leverage trading finite: at some point, if a position moves far enough against you, the exchange forcibly closes it.
Understanding crypto liquidation isn't just academic. Knowing exactly what triggers it, how to calculate the price at which it happens, and what you can do to avoid it is the difference between a manageable loss and a completely depleted trading account. This guide covers all of it.
What Is Liquidation in Crypto Trading?
Liquidation occurs when the losses on a leveraged position consume your margin to the point where it falls below the exchange's maintenance margin requirement. At that threshold, the exchange automatically closes your position — regardless of whether you want it to — to prevent your balance going negative.
The exchange takes this action to protect itself. When you trade with leverage, you're effectively using the exchange's capital for the borrowed portion of your position. If your losses exceed your collateral, the exchange is left with an uncovered loss. Liquidation is the mechanism that prevents that.
From your perspective, liquidation means losing the margin you allocated to that position. From the exchange's perspective, it's risk management.
How Liquidation Price Is Calculated
Every open leveraged position has a specific liquidation price — the exact price level at which your margin runs out. You should know this number before you confirm any trade.
For Long Positions
When you're long (betting on price rising), your liquidation price is below your entry:
Liquidation Price ≈ Entry Price × (1 − 1 / Leverage)
Example — Long BTC at $90,000 with 10x leverage:
Liquidation Price = $90,000 × (1 − 1/10) = $90,000 × 0.9 = $81,000
BTC needs to drop 10% from your entry to trigger liquidation.
Example — Long BTC at $90,000 with 50x leverage:
Liquidation Price = $90,000 × (1 − 1/50) = $90,000 × 0.98 = $88,200
With 50x leverage, just a 2% decline triggers liquidation. In crypto, that's a single volatile candle.
For Short Positions
When you're short (betting on price falling), your liquidation price is above your entry:
Liquidation Price ≈ Entry Price × (1 + 1 / Leverage)
Example — Short BTC at $90,000 with 10x leverage:
Liquidation Price = $90,000 × (1 + 1/10) = $90,000 × 1.1 = $99,000
BTC needs to rise 10% against you to trigger liquidation.
These formulas give approximate values — the actual number shown by the exchange accounts for maintenance margin rates and fees, which vary slightly per platform. BYDFi displays the exact liquidation price in your order confirmation panel and on your open positions screen. Always check it.
Isolated Margin vs Cross Margin: How Each Affects Liquidation
Your margin mode is one of the most important decisions you make before opening a leveraged position, and it directly determines how liquidation plays out.
Isolated Margin
With isolated margin, you allocate a specific amount of USDT to a single trade. That's the maximum you can lose on that position. If the trade moves against you and hits the maintenance threshold, the exchange liquidates just that position — it cannot touch the rest of your account balance.
Example: You have $10,000 in your account. You open an isolated margin position using $1,000 as margin. If you get liquidated, you lose $1,000 — the remaining $9,000 is untouched.
Isolated margin is the right choice for most traders, especially beginners. Your risk is defined and contained.
Cross Margin
With cross margin, your entire account balance serves as collateral for all open positions. This gives each individual position more buffer before liquidation — the exchange can draw from your full balance to keep it open — but it also means a series of losing positions can drain your entire account.
Example: You have $10,000 in your account and open multiple cross-margin positions. If one position runs into trouble, the exchange pulls from your full $10,000 balance to maintain it. If all positions move against you simultaneously, your entire account can be liquidated.
Cross margin has legitimate uses — primarily for sophisticated traders who are actively managing multiple correlated positions. For everyone else: use isolated margin.
Partial Liquidation vs Full Liquidation
Not all liquidations wipe out your entire position. Many exchanges, including BYDFi, use partial liquidation as a first step to reduce exposure and potentially save part of your position.
When your margin ratio approaches the maintenance threshold, the exchange may close a portion of your position — enough to bring your margin ratio back to a safer level. If the position continues moving against you, further partial liquidations follow until either the position stabilizes or is fully closed.
This system is gentler than a single full-position liquidation, but the outcome is still significant losses. Don't rely on partial liquidation as a substitute for a stop-loss — it's a last-resort mechanism, not a risk management tool.
The Insurance Fund and Auto-Deleveraging (ADL)
What happens when a position is liquidated but the market moves so fast that it can't be closed before going into negative equity — meaning the trader would technically owe the exchange money?
The Insurance Fund
Most exchanges maintain an insurance fund to cover these scenarios. If a liquidation order fills at a better price than the bankruptcy price (the point of zero margin), the difference goes into the insurance fund. If a liquidation fills at worse than the bankruptcy price, the insurance fund covers the shortfall.
BYDFi maintains an insurance fund for each trading pair. You can usually view its size in the platform — a healthy, growing insurance fund signals that the exchange's liquidation system is working well.
Auto-Deleveraging (ADL)
If the insurance fund is depleted or insufficient, exchanges use auto-deleveraging as a backstop. ADL automatically reduces the positions of the most profitable traders on the opposite side to cover the loss. This is rare in normal market conditions but can occur during extreme volatility events.
Neither mechanism should be something you expect to encounter. They exist for tail-risk scenarios. The practical takeaway: set stop-losses before the liquidation price so your position is never in a situation that requires these systems to activate.
6 Ways to Avoid Liquidation
1. Use Lower Leverage
The single most effective way to avoid liquidation is to use less leverage. Lower leverage means a wider buffer between your entry and your liquidation price — more room for the market to move against you without ending your trade.
The leverage trading guide recommends starting at 2x–5x for beginners. That advice exists primarily to prevent liquidation during normal market volatility.
2. Set a Stop-Loss Before Your Liquidation Price
A stop-loss is your first line of defense against liquidation. Set it at the price where your trade thesis is clearly wrong — based on technical analysis and support/resistance levels — well before the liquidation price is reached.
Your stop-loss should trigger long before the exchange needs to liquidate you. If your stop is at $85,000 and your liquidation is at $81,000 on a BTC long, you exit cleanly at $85,000 rather than getting wiped out at $81,000. The discipline of placing proper stop-loss orders on every leveraged trade is the most practical habit a leverage trader can build.
3. Monitor Your Margin Ratio
Your margin ratio shows how close your position is to the maintenance margin threshold. A ratio of 100% means you're at liquidation. Most exchanges display this prominently on open positions.
When your margin ratio climbs above 50–60% — meaning you've used more than half your buffer — it's time to reassess. Either exit, reduce position size, or add margin (see below).
4. Add Margin to Extend Your Buffer
If a position is moving against you but you still believe in the trade, you can add more margin to push the liquidation price further away. This lowers your effective leverage and gives the trade more room.
Be careful with this approach. Adding margin to a losing position is a form of averaging down with leverage. Do it only when you have a specific, logical reason to stay in — not simply to avoid accepting a loss.
5. Reduce Position Size During High-Volatility Events
Known volatility events — major economic data releases, Fed decisions, scheduled protocol upgrades, token unlocks — can cause sudden large moves that trigger liquidations even on well-structured trades. Reducing leverage or position size before these events is a professional risk management habit. You can always re-enter after the volatility resolves.
6. Avoid Holding High-Leverage Positions Overnight
Crypto trades 24/7. A high-leverage position left open overnight is exposed to whatever happens while you're asleep — an exchange hack, a regulatory announcement, a major liquidation cascade on another platform. Either reduce leverage before stepping away from the screen or use lower leverage that can survive large moves without your active management.
Common Mistakes That Lead to Liquidation
Chasing entries with high leverage. Entering at a worse price than planned with the same leverage ratio means a tighter stop to liquidation. If you miss your ideal entry, recalculate — don't just proceed with the original leverage.
Not accounting for funding rate erosion. On long-hold perp positions, ongoing funding payments eat into your margin, bringing your liquidation price progressively closer even if price doesn't move. Factor this into your margin planning for any position you intend to hold for multiple days.
Using cross margin without understanding the implications. Beginners who accidentally use cross margin instead of isolated margin can find their entire account balance at risk without realizing it. Check your margin mode before every trade.
Adding to losing positions without logic. "Averaging down" by adding margin or opening additional positions in the same direction as a losing trade is how small losses become account-ending ones. If the trade isn't working, exiting and reassessing is almost always the better choice.
A disciplined crypto trading strategy that accounts for liquidation risk on every trade prevents these from becoming costly habits.
FAQ
What is liquidation in crypto trading?
Liquidation occurs when the losses on a leveraged position consume your margin to the point where it falls below the exchange's maintenance margin threshold. The exchange automatically closes the position to prevent negative equity. You lose the margin allocated to that trade.
How do I calculate my liquidation price in crypto?
For long positions: Liquidation Price ≈ Entry Price × (1 − 1/Leverage). For short positions: Liquidation Price ≈ Entry Price × (1 + 1/Leverage). These are approximations — your exchange calculates the exact number based on maintenance margin rates and fees, and displays it in your order panel before you confirm.
What is the difference between isolated and cross margin liquidation?
With isolated margin, only the funds allocated to that specific trade can be lost in a liquidation. The rest of your account is safe. With cross margin, your entire account balance is collateral — a liquidation can consume your full balance. Most traders should use isolated margin to contain individual trade risk.
Can I get my money back after a crypto liquidation?
No. Once liquidated, the margin used to collateralize that position is gone. The exchange used it to cover the losses on the trade. This is why stop-losses before the liquidation price are critical — they let you exit with a defined, manageable loss rather than losing your entire position margin.
What is an insurance fund in crypto trading?
An exchange's insurance fund covers gaps when a liquidated position can't be closed before going into negative equity. It's funded by the difference between liquidation prices and bankruptcy prices on successful liquidations. A healthy, growing insurance fund signals the exchange's risk management system is working effectively.
