Crypto Liquidation Explained | How It Works & 5 Mistakes That Get Traders Liquidated

Over $740 million in crypto positions were liquidated in a single 24-hour period on February 3, 2026, when BTC dropped to a 14-month low before bouncing back above $76,000. On Pi Day, March 14, another wave wiped out hundreds of millions more. Every time the market moves sharply, the same pattern plays out. Leveraged traders who did not understand their liquidation price wake up to empty accounts and a hard lesson about how margin actually works.

With the FOMC meeting on March 18 and BTC trading in a $65,600-$72,500 range, another volatility spike is coming. BTC has dropped after 7 of 8 FOMC meetings in 2025, and the January 2026 meeting produced a 7.3% drop in 48 hours. If you are trading with leverage this week, understanding liquidation is not optional.

Here is how it works, how to calculate your exact liquidation price before opening any trade, and the five most common mistakes that get traders liquidated unnecessarily.

What Is Liquidation?

When you trade with leverage, you control more capital than you deposited. A $1,000 deposit with 10x leverage gives you $10,000 in market exposure, amplifying both gains and losses equally. If the price moves against you far enough that your $1,000 margin is used up, the exchange closes your position automatically. It does not ask permission. Your margin is gone and the trade is over.

Exchanges do this because the leveraged capital came from somewhere, usually the platform’s liquidity pool or the counterparty on the other side of your trade. The liquidation mechanism prevents a scenario where a trader’s losses exceed their deposit, which would create a debt that destabilizes the platform. For the trader, the result is binary. Your position is forcibly closed and your collateral is lost, sometimes in minutes, sometimes in seconds during a fast move.

How to Calculate Your Liquidation Price

Before you open any leveraged position, you should know exactly where it gets liquidated. The math is not complicated, and the number should be checked before every single trade.

Here is a worked example using BTC at $71,000:

1. You have $1,000 in your account

2. You open a 10x leveraged LONG on BTC at $71,000

3. That gives you $10,000 in notional exposure (approximately 0.141 BTC)

4. Liquidation price = entry price minus (margin / position size in BTC)

5. $71,000 minus ($1,000 / 0.141) = approximately $63,900

BTC only needs to fall about 10% from your entry for your entire margin to be wiped. Here is how leverage changes that equation:

At 50x leverage, a 2% move against you ends the trade. BTC regularly moves 2% in an hour during volatile sessions. At 100x, a single bad candle on a 5-minute chart can liquidate you before you even check your phone.

One detail that catches traders off guard. Most exchanges do not liquidate exactly when your initial margin hits zero. They liquidate earlier, when your remaining equity drops to the “maintenance margin” level (typically 0.5-1% of position value). This means your actual liquidation price is slightly worse than the simple calculation, slightly higher for longs and slightly lower for shorts.

Phemex shows the exact liquidation price in the position panel both before and after you open a trade. Always verify this number before confirming any leveraged position.

Mark Price vs. Last Price

This is a detail that matters more than most traders realize, especially during volatile events like FOMC announcements.

Phemex and most major exchanges use “mark price” rather than “last traded price” to trigger liquidations. The mark price is calculated from an index of prices across multiple exchanges, which prevents a single platform’s order book from being manipulated to trigger mass liquidations. If one exchange experiences an artificial wick driven by a large market sell on thin liquidity, the mark price across the broader market may not reflect that spike, and your position stays open.

During FOMC week, this distinction becomes especially relevant. Algorithmic trading surges in the 15-30 minutes after the 2:00 PM ET statement, and individual exchanges can experience brief price dislocations that do not reflect the broader market. Mark price-based liquidation smooths out those anomalies.

You can see the mark price on Phemex’s trading interface next to your position details. If you ever notice a large gap between last traded price and mark price, pay attention to it, because that difference is the buffer between you and a liquidation triggered by a single-exchange anomaly.

Isolated Margin vs. Cross Margin

How you set your margin mode determines how much of your account is at risk if a trade goes wrong.

Isolated margin means only the margin you assign to a specific trade is at risk. If you allocate $1,000 to a BTC long with isolated margin and the trade gets liquidated, you lose $1,000 and the rest of your account balance is untouched. This is the safer option for most traders because it caps your maximum loss per trade.

Cross margin means your entire account balance serves as margin for all your open positions. This gives each position more room before liquidation (because the full balance backs it), but if the trade moves far enough against you, your entire account is at stake. Multiple positions going wrong simultaneously under cross margin can drain your full account in a single event.

For FOMC week specifically, isolated margin is the lower-risk choice because it prevents a bad outcome on one position from cascading into your entire portfolio.

The 5 Most Common Liquidation Mistakes

These are the errors that show up repeatedly in liquidation data during every major volatility event, and all five are avoidable.

6. Not checking the liquidation price before entry.

Many traders open a leveraged position, glance at the entry price, and walk away. They come back an hour later to find the position liquidated because they never verified where the threshold sat relative to recent support levels.

On Phemex, the liquidation price is displayed in the position panel before you confirm the trade. If your liquidation price sits above a recent support level on a long (or below recent resistance on a short), the trade does not have enough room to survive normal movement. Adjust the leverage or position size before entering.

7. Not using stop-losses.

A stop-loss closes your position at a predetermined price before you reach liquidation. Your loss is controlled and predictable. Without one, the exchange decides when you exit, and that exit happens at the worst possible price, the liquidation level itself.

Consider a BTC long entered at $71,000. A stop-loss at $66,000 costs you roughly 7% if triggered. Liquidation at $63,900 costs you 100% of your margin. The stop-loss converts an all-or-nothing gamble into a defined, survivable risk.

8. Max leverage on volatile events.

Opening a 20-50x position before FOMC, CPI, or geopolitical news is the single most common path to liquidation. At 20x, a 5% move against you ends the trade.

BTC moved 7.3% in 48 hours after the January FOMC meeting. During the February crash, it moved 15% in a single day. The Phemex FOMC playbook recommends 2-3x maximum leverage during high-volatility events, and the historical data strongly supports that approach.

9. Adding margin to a losing position.

When a trade moves against you and approaches liquidation, the instinct is to deposit more margin to push the liquidation price further away. This is throwing good money after bad. You extend the position’s life, but if the trend continues, you now lose the original margin plus everything you added.

Unless you have a specific thesis for why price will reverse at a defined level, adding margin to a losing position usually just delays and enlarges the final loss.

10. Ignoring funding rates.

On perpetual futures contracts, funding rates are periodic payments between long and short traders that keep the contract price aligned with spot. When funding is positive, longs pay shorts. When funding is negative, shorts pay longs.

If you hold a leveraged position for days with adverse funding, those payments quietly erode your margin balance, pulling your effective liquidation price closer without the market even moving. Check the funding rate and its payment schedule before holding any position overnight, and factor the cost into your position sizing.

FOMC Week Context: Why This Matters Right Now

BTC is trading between $65,600 and $72,500 as of March 16. The FOMC announces at 2:00 PM ET on March 18. If the announcement triggers a $5,000 move in either direction (which is within the range of recent FOMC reactions), the math for leveraged positions is unforgiving.

A 10x leveraged long opened at $71,000 with $1,000 margin gets liquidated if BTC drops to roughly $63,900. A $5,000 drop from $71,000 puts the price at $66,000, still $2,100 above that liquidation level, but a $7,000 move (the size of the January FOMC reaction) would end the trade entirely. At 20x, a $5,000 move liquidates the position outright.

The safe approach for this week is simple. Keep leverage at 2-3x maximum, use isolated margin, set stop-losses before the announcement, and if you are not comfortable with the risk, move to spot-only positions or stablecoins until the volatility passes. The 48-hour window after the announcement is where most of the damage historically occurs.

Patience is cheaper than liquidation.

Frequently Asked Questions

What is liquidation in crypto?

Liquidation is when a leveraged position is automatically closed by the exchange because the trader’s margin has been consumed by losses. The exchange closes the position to prevent the account from going negative, and the trader loses the margin they deposited for that trade.

How do I check my liquidation price?

On Phemex, the liquidation price is displayed in the position panel both before and after you open a trade. Verify this number before confirming any leveraged position and compare it to nearby support or resistance levels to confirm the trade has enough room to survive normal price movement.

What leverage is safe during FOMC week?

Historical data shows BTC dropped an average of roughly 5% in the 48 hours after FOMC meetings throughout 2025. At 10x leverage, that 5% becomes a 50% account drawdown. The recommended maximum during high-volatility macro events is 2-3x, which keeps the potential drawdown manageable even if the worst-case scenario plays out.

What is the difference between isolated and cross margin?

Isolated margin limits your risk to the margin assigned to one specific trade. Cross margin uses your entire account balance as collateral across all positions. Isolated is safer per-trade because a liquidation only costs the allocated margin. Cross margin provides more room before liquidation but puts your full account at risk.

Bottom Line

Liquidation is not a market event. It is a risk management failure. Every liquidation happens because a trader took more leverage than the price range could support, did not set a stop-loss, or did not check where their position would be forcibly closed before opening it.

The traders who survive FOMC weeks, flash crashes, and liquidation cascades are not the ones with better predictions. They are the ones who sized their positions so that being wrong did not cost them everything. Knowing your liquidation price, using stop-losses, keeping leverage low during volatility, and choosing isolated margin are the four decisions that separate a controlled loss from an account wipeout.

Check the number before you enter the trade. That is the entire lesson.
