Recently, many people have been liquidated directly in futures trading because they don't understand the concept of margin ratio. In fact, most of these situations can be avoided.

Let's start with the most critical point. When your margin ratio reaches 100%, the exchange will begin to liquidate your position. How is this ratio calculated? It’s the maintenance margin divided by the margin balance. It sounds simple, but many people don’t understand it, and as a result, they get liquidated with only slight price fluctuations. I think this is the most easily overlooked risk point.

Here's an example. Suppose you have 500 USDT in your account, and you open a 1,000 USDT BTC long position with 50x leverage at a price of $50,000. It seems like a good profit opportunity, but your liquidation price is actually locked at $25,100.40. Once the price drops to that level, your position is gone. That’s why monitoring the margin ratio is so important — it directly determines how much loss you can withstand.

So how can you reduce the risk of liquidation? The most straightforward way is to increase your margin balance. The more money you have in your account, the lower the liquidation price, and the stronger your risk resistance. Many exchanges have calculation tools; you can try adjusting your balance to see how the liquidation price changes.

The second tip is to always use stop-loss orders. A stop-loss order automatically executes when the price reaches your set level, helping you exit early. For example, if you set a stop-loss at a 20% decline from your entry price, then when BTC drops from $40,000 to $32,000, the order will trigger. This way, you won’t keep falling until you get liquidated.

The last common pitfall is—never add to a losing position. I’ve seen too many people try to “average down,” only to end up in an even worse situation. Losing positions already consume your margin; adding more will only speed up liquidation. Instead, maintain a safe margin ratio and cut losses when necessary.

Futures trading’s biggest danger is passive liquidation. Once it happens, you lose everything. So instead of gambling on the market, it’s better to focus on risk control. Monitoring the margin ratio, setting stop-losses, and controlling your position size — doing these three well will greatly reduce the chance of liquidation.
