Recently, a friend asked me what liquidation in virtual currencies means, and I realized that many beginners really don’t understand this concept clearly. Actually, liquidation, to put it simply, is when your trading position moves against the market, losing so much that you can’t cover your margin, and then the system automatically closes all your positions. That’s liquidation.

I’ve seen quite a few people suffer big losses because of this. During intense market volatility, if you’re not careful, your principal can evaporate instantly, and sometimes you even end up owing money. It’s really quite scary.

Why does liquidation happen? There are usually a few reasons. The most common one is opening too much leverage. I’ve seen someone use 100k yuan of capital with 10x leverage to trade futures, which is like trading a 1 million yuan position. Just a 1% move against you, and your principal loses 10%. Think about how risky that is. From my experience, leverage is like a double-edged sword; it can amplify gains, but risks also double.

Another common pitfall is holding onto losing positions with the mindset of “waiting for a rebound.” Many people think, “It’ll bounce back soon,” but then they encounter a gap-down drop, get liquidated at market price, and lose far more than expected. I’ve seen this happen too many times.

There are also some hidden costs that are easy to overlook, such as holding a day trade position that isn’t closed, and then a gap-up the next day causes a liquidation. Or trading options as a seller, where a surge in volatility causes margin requirements to suddenly double. Liquidity traps are also a concern—trading less popular assets with wide bid-ask spreads can lead to stop-loss orders being executed at absurd prices.

When it comes to cryptocurrency liquidation, the risk is especially high. Crypto assets are highly volatile; for example, Bitcoin’s 15% fluctuation can cause a large number of investors to get liquidated. The worst part is, during crypto liquidation, not only is your margin wiped out, but the coins you hold can also disappear.

Forex margin trading is also high risk. Many people like to use leverage, playing big with small amounts. How is margin calculated? It’s the contract size times the number of lots, divided by the leverage. When your account’s margin level drops to the platform’s minimum, forced liquidation occurs. I’ve seen accounts with remaining balances but with losses reaching 90%, and the system still closes the positions—that’s liquidation.

Stocks are somewhat safer. Trading with 100% of your own funds means that even if the stock price drops to zero, you only lose your principal, and you won’t owe the broker money. But if you buy on margin, and your maintenance margin falls below 130%, you’ll receive a margin call. If you don’t add funds, your positions will be liquidated. Day trading that fails and leaves positions overnight also carries risks—if the market gaps down to the limit down the next day, the broker will directly liquidate your positions.

To avoid liquidation, risk management tools are very important. Setting stop-loss and take-profit orders is like a safety net for trading. Stop-loss sets an automatic sell price; when the stock hits that price, the system automatically sells. Take-profit sets an automatic profit target; when the stock reaches that price, it automatically locks in gains. These two features are crucial—they help you control risk and prevent losing everything in one go.

You also need to calculate the risk-reward ratio properly. Simply put, your potential gains should outweigh your potential losses. Beginners can use a percentage method, setting 5% above and below the entry price, so you don’t have to watch the screen anxiously all day.

Another important protective mechanism is negative balance protection. On regulated exchanges, this is a required safeguard. Basically, it means you can only lose the money in your account—you won’t end up owing the broker a huge debt. This protection mainly helps beginners, giving them some room to make mistakes.

My advice is that beginners should first learn trading knowledge thoroughly and make good use of risk management tools to set stop-loss and take-profit levels. Don’t be tempted by high leverage; practicing steadily is more important than anything. Investing involves both gains and losses, but as long as you know how to control risk, you can survive longer in the market.
