Liquidation
Understanding Liquidation in Cryptocurrency Trading
Welcome to the world of cryptocurrency trading! It’s exciting, but it can also be risky. One of the most important concepts for new traders to understand is *liquidation*. This guide will break down what liquidation is, why it happens, and how to avoid it. We'll focus on the context of *leverage* trading, as that's where liquidation is most common.
What is Liquidation?
Imagine you want to buy a house worth $200,000, but you only have $20,000 saved. You could take out a mortgage (a loan) for the remaining $180,000. This is similar to using *leverage* in crypto trading.
Leverage lets you control a larger position in a cryptocurrency with a smaller amount of your own money. For example, with 10x leverage, $100 of your money can control $1,000 worth of Bitcoin. This magnifies both your potential *profits* and your potential *losses*.
Liquidation happens when a trade goes against you so much that your account doesn't have enough funds to cover your losses. The exchange (like Register now Binance) then *automatically closes* your position to prevent you from owing them money. Essentially, they sell your cryptocurrency, even if you don’t want them to, to cover the losses.
Think of it like this: if the bank believes you won't be able to repay your mortgage, they can *foreclose* on your house. Liquidation is the crypto equivalent of foreclosure.
Why Does Liquidation Happen?
Liquidation is triggered when your *margin ratio* falls below a certain level.
- Margin* is the amount of money you put up as collateral to open a leveraged trade.
- Margin Ratio* is calculated as: (Your Account Value / Your Position Value) x 100%.
Exchanges have a *maintenance margin* requirement. This is the minimum margin ratio you must maintain. If your margin ratio drops below this level, your position will be liquidated.
Let's say you open a trade with $100 and 10x leverage, controlling $1,000 worth of Bitcoin. Your initial margin ratio is 10% ($100 / $1,000 x 100%). If the price of Bitcoin moves against you and your losses reach $90, your account value will be $10. Your margin ratio becomes 1% ($10 / $1,000 x 100%). If the maintenance margin is 5%, your position will be liquidated.
Types of Liquidation
There are two main types of liquidation:
- **Partial Liquidation:** The exchange closes a portion of your position to bring your margin ratio back above the maintenance margin. This is preferable to total liquidation, as you retain some of your position.
- **Full Liquidation:** The exchange closes your entire position. You lose all the margin used for that trade.
How to Avoid Liquidation
Here are some practical steps to help you avoid getting liquidated:
1. **Use Lower Leverage:** The higher the leverage, the smaller the price movement needed to trigger liquidation. Start with lower leverage (e.g., 2x or 3x) until you’re more comfortable with the risks. 2. **Set Stop-Loss Orders:** A *stop-loss order* automatically closes your position when the price reaches a specific level. This limits your potential losses and reduces the risk of liquidation. See Stop-Loss Orders for more information. 3. **Manage Your Position Size:** Don't risk too much of your capital on a single trade. Consider your *risk tolerance* and only use a small percentage of your account for each trade. 4. **Monitor Your Margin Ratio:** Regularly check your margin ratio on the exchange. Most exchanges will send you alerts when your margin ratio gets close to the liquidation level. 5. **Add Margin:** If your margin ratio is dropping, you can add more margin to your account to prevent liquidation. This is essentially adding more collateral to your trade. 6. **Understand Funding Rates:** In perpetual futures contracts, *funding rates* can impact your account balance. Negative funding rates mean you pay a fee, reducing your margin.
Comparing Leverage and Risk
Here's a table illustrating the impact of leverage on liquidation risk:
| Leverage | Potential Profit | Potential Loss | Liquidation Risk |
|---|---|---|---|
| 1x | Moderate | Moderate | Low |
| 5x | High | High | Moderate |
| 10x | Very High | Very High | High |
| 20x | Extremely High | Extremely High | Very High |
Understanding Liquidation Price vs. Mark Price
It's important to understand the difference between the *liquidation price* and the *mark price*.
- **Liquidation Price:** The price at which your position will be liquidated. This is calculated based on your entry price, leverage, and margin.
- **Mark Price:** The current price of the cryptocurrency as determined by the exchange, often based on the price from multiple other exchanges. Exchanges use the Mark Price to prevent *manipulation* and ensure fair liquidations.
Liquidation is generally triggered by the Mark Price, not the last traded price on the exchange.
Advanced Considerations
- **Insurance Funds:** Some exchanges have an *insurance fund* that can cover a portion of liquidation losses, but don’t rely on this.
- **Partial Fill Liquidation:** In fast-moving markets, your liquidation order might only be partially filled, resulting in a worse price than expected.
- **Hidden Fees:** Be aware of trading fees, as these can also contribute to liquidation.
