Liquidation

What is Liquidation?

Liquidation is when a platform force sells your position to repay what you borrowed because your account fell below safety levels. Think of it like a fire alarm that auto calls the firefighters, except the firefighters sell your stuff to stop the flames. Simple, a bit harsh, and very effective.

How Liquidation works

Here is the play by play with a quick scenario.

• Step 1: You open a position using margin trading and deposit collateral.
• Step 2: Price moves against you, so your equity shrinks compared to the amount you borrowed.
• Step 3: The platform checks a maintenance level. If your equity falls beneath it, an alert fires and the engine prepares a forced close.
• Step 4: The system sells assets or closes contracts to repay the loan, often in chunks to reduce price impact.
• Step 5: Fees get taken, any leftover balance stays with you. If the move was severe, you might end near zero and the insurance fund or ADL may kick in.

Not pretty, but it keeps markets from turning into unpaid IOUs.

Why Liquidation Matters

So what should you care about?

• Benefit: It protects lenders and venues from defaults, which lets you borrow and trade with confidence.
• Perspective: Cascading forced closes can speed up selloffs or short squeezes, which is why charts sometimes look like a waterslide.
• Relevance: You will see it on lending protocols, perpetuals, and futures trading venues every single week.

Key Characteristics of Liquidation

What sets it apart:

• Automated: Engines or keeper bots do the selling without waiting for your permission.
• Threshold: Triggered by maintenance requirements that factor price, interest, and fees.
• Sizing: The chance goes up as your leverage and position size go up.

Variations

Same theme, different flavors:

• Exchange: Centralized engines match orders and may use insurance funds for gaps.
• On chain: Keeper bots race to liquidate and earn a bonus for doing it fast.
• Cross: All positions share equity, which can save one trade but risk the rest.
• Isolated: Each position has its own margin, so damage stays contained.
• Partial: Only part of a position is closed to restore health, instead of closing everything.

Example

You long an asset with borrowed funds, price drops ten percent, your equity falls beneath maintenance, and the system auto sells part of your position to repay the loan.

Fun Fact

Old school brokers in commodity pits used the same idea long before crypto. If a farmer could not meet a margin call, the firm would close the wheat contract on the spot, then mail a stern letter.

Wrap-Up

Takeaway: borrow only what you can buffer, know your close out level, and let your future self sleep better.
