Recently, many beginners have been scared and asked me, "What does liquidation mean?" It actually means you guessed the wrong direction, losing so much that you can't even cover the margin, and the system automatically liquidates your position. Today, I will break down this issue thoroughly so that everyone's hard-earned money doesn't evaporate in an instant.

Simply put, liquidation occurs when your trading direction goes against the market, and your principal (net worth) drops below the minimum margin requirement set by the broker. The system will automatically close all your positions. Not only do you lose all your principal, but in some cases, you may even owe money to the broker.

Why does liquidation happen? The most common reason is using too much leverage. For example, using 100k yuan of capital to trade futures with 10x leverage means you're controlling a 1 million yuan position. At this point, just a 1% move against your position will wipe out 10% of your principal. If the market moves 10% in the opposite direction, your margin is completely lost, leading to forced liquidation. Many people initially think they can control the risk, but market changes are often much faster than expected.

Another common mistake is holding onto losing positions with a stubborn mindset. Thinking "it will rebound soon," but then encountering a gap-down drop, the broker liquidates at market price at open, resulting in losses far beyond expectations. Some also overlook hidden costs, like additional margin requirements for day trading that hasn't been cleared, causing a gap-down the next day and a liquidation. Or when selling options, volatility spikes can suddenly double margin requirements. Liquidity traps are also dangerous; trading less popular assets with wide bid-ask spreads can cause stop-loss orders to execute at absurd prices.

The risk of liquidation varies greatly across different assets. Cryptocurrencies, due to their high market volatility, are considered high-risk. A 15% fluctuation in Bitcoin can cause most investors on the network to be liquidated. Forex margin trading is also a game of using small money to control large positions; many traders like to leverage to reduce margin requirements. The margin calculation differs for standard, mini, and micro lots. When your account margin ratio drops below the platform's minimum (usually 30%), forced liquidation occurs.

In stocks, trading with 100% of your own funds is the safest—if the stock drops to zero, you only lose your principal, with no debt owed. But if you buy stocks on margin, a maintenance margin below 130% will trigger a margin call, and if you don't add funds, your position will be liquidated. Day trading failures can also lead to liquidation; if a gap-down causes a stock to hit the limit down and you can't sell, the broker will directly liquidate your position.

To prevent liquidation, risk management tools are essential. Stop-loss and take-profit functions are crucial—they automatically set sell prices and profit targets, helping the system control risk. Beginners can use simple percentage methods, like setting 5% above or below the purchase price. There’s also a negative balance protection mechanism; regulated platforms must protect leveraged trading investors, at most risking losing all account funds, without owing a huge debt.

Ultimately, investing involves both gains and losses. When trading with leverage, caution is a must. Before making any trade, thoroughly understand trading knowledge and make good use of risk management tools to set stop-loss and take-profit points, which will benefit long-term investment planning. Beginners are advised to start with cash stocks to avoid waking up to a margin call. For options trading, start with micro lots to gradually familiarize yourself with the market. Don’t over-leverage; 10x or less is enough for beginners. Most importantly, always set a stop-loss—never stubbornly fight the market.
