There's something in the trading market that always makes beginners nervous—that's liquidation. Today, let's have a thorough discussion about what liquidation really means, why it happens, and how to avoid this pitfall.

Simply put, liquidation means you bet against the market direction, and when your losses deplete your margin to the point where you no longer have enough collateral, the system forcibly closes your position. When your principal drops below the minimum margin requirement set by the broker, the system automatically liquidates all your positions, giving you no chance to turn things around. At this moment, your capital instantly evaporates, and in severe cases, you might even owe money.

Why is liquidation so easy to happen? There are mainly two reasons. First, your trading direction is opposite to the market. Second, you lose so much that you can't even cover the margin, and your equity falls below the maintenance margin standard.

The most common trap leading to liquidation is using too much leverage. High leverage is like a double-edged sword; it can amplify profits, but risks grow proportionally. For example, if you use 100k yuan of capital to trade with 10x leverage, you're controlling a position worth 1 million yuan. If the market moves just 1% against you, your capital loses 10%. If the move reaches 10%, your margin is wiped out, and you face a margin call and forced liquidation.

Another common mistake is having a stubborn mindset. Many people think, "It will bounce back if I wait a little longer," but then a gap-down occurs, and the broker liquidates at market price at the open, resulting in losses far beyond expectations.

Hidden costs are also easily overlooked. If you don't close your day trades and forget to add margin for holding overnight, a gap can cause an instant liquidation. Or if you're selling options, a surge in volatility can suddenly double the margin requirement. Liquidity traps are also dangerous—trading obscure assets or during night sessions, where bid-ask spreads are large, can cause stop-loss orders to execute at absurd prices.

The liquidation risk varies greatly across different assets. Cryptocurrencies, due to their high market volatility, are considered high-risk. Previously, Bitcoin's 15% swings caused most investors to be liquidated. When crypto liquidates, not only is the margin wiped out, but the coins you bought can also disappear.

Forex margin trading allows you to play big with small money. How is margin calculated? It’s the contract size times the lot size, divided by the leverage. For example, placing a 0.1 lot order of currency pair A with 20x leverage, assuming the value is $10k, requires a margin of $500. When your account margin ratio drops to the platform's minimum (usually 30%), the broker will forcibly close your position.

Stocks also carry liquidation risks. Trading with 100% of your own funds is safest—if the stock drops to zero, you only lose your principal. But if you buy on margin, falling below a maintenance ratio of 130% will trigger a margin call, and if you don’t add funds, your position will be liquidated. If a day trade fails and you hold the position overnight, a gap-down can cause a limit-down sell that you can't unload, leading the broker to liquidate your position directly.

Want to avoid liquidation? Risk management tools are your lifesavers. Stop-loss orders automatically sell your position when the price hits a set level, preventing losses from snowballing. Take-profit orders automatically lock in gains when the target price is reached. Both features are extremely important.

The risk-reward ratio should also be calculated carefully—profitable trades should earn more than they risk. The lower the ratio, the more worthwhile the trade. For example, risking 1 dollar to make 3 dollars is quite good. Beginners can use a simple percentage method, setting buy and sell points at 5% above and below the entry price, so they don’t have to watch the screen anxiously all day.

Regulated exchanges often provide negative balance protection, meaning you can only lose up to your account balance and won’t owe money to the broker. If you do lose everything, the broker absorbs the remaining losses.

A straightforward tip for beginners: start with cash stocks, using spare money to buy stocks so you won’t wake up to a margin call. Avoid leverage products and futures contracts until you gain more experience. Keep your strategy stable—dollar-cost averaging is safer than going all-in. If you must trade futures, start with micro lots, keep leverage below 10x, and always set stop-losses. Never fight the market blindly.

Investing involves both gains and losses. Before trading, you should thoroughly understand trading knowledge and make good use of risk management tools to set stop-loss and take-profit levels. This helps with long-term investment planning. Understanding the risks of liquidation is more important than blindly chasing high returns.
