Liquidation is the most painful thing in futures trading — your margin gets wiped out to zero and the system forcibly closes your position. But liquidation isn't bad luck. In the vast majority of cases, it's entirely preventable.
How Liquidation Happens
When your position's losses grow to the point where your remaining margin falls below the required maintenance margin, the system triggers forced liquidation. In plain terms: you've lost so much that you're almost out of money, so the system stops the bleeding for you.
In isolated margin mode with 10x leverage going long on BTC, a price drop of roughly 10% will trigger liquidation. With 20x leverage, it only takes about a 5% drop.
How to Check Your Liquidation Price
On the Binance futures page, each open position displays a Liquidation Price. This number is your lifeline — when the market reaches it, your position is gone.
The first thing to do after opening a position is check how far the liquidation price is from the current price. If it's too close (say, less than 3% away), your position is at extremely high risk.
Five Practical Ways to Prevent Liquidation
1. Lower your leverage
The lower the leverage, the farther your liquidation price is from the current market. 3–5x leverage gives you plenty of breathing room.
2. Control your position size
Don't put all your funds into a single position. Each position should be no more than 10%–20% of your total capital.
3. Always set a stop-loss
Set your stop-loss at the same time you open your position. For example, auto-close if the loss reaches 20% of your margin. Don't let losses grow unchecked.
4. Monitor your margin ratio
On the Binance futures page, when the Margin Ratio approaches 100%, you're in serious danger. Keep it below 50%.
5. Use isolated margin mode
In isolated mode, liquidation only costs you the margin allocated to that one position. In cross margin mode, liquidation can eat through all the funds in your account.

Risk Warning: Even with risk management measures in place, futures trading still carries the risk of losing your principal. In extreme market conditions, prices can gap instantly, and stop-losses may not fill at your expected price. Please trade within your means.
