Before opening a position on Binance futures, you need to choose a margin mode: Isolated or Cross. This choice directly affects your risk level, so don't just stick with the default setting.
Isolated Margin: Capped Losses
In isolated margin mode, you allocate a specific amount of margin to each position. If that position gets liquidated, you only lose the margin assigned to it — the rest of your account balance stays untouched.
Example: You have 1,000 USDT in your account and use 200 USDT to open a BTC long position in isolated mode. Even if you get liquidated, the maximum loss is 200 USDT — the remaining 800 USDT is completely safe.
Think of isolated margin as a firewall around each position.
Cross Margin: All Funds Share the Risk
In cross margin mode, your entire available balance in the futures account serves as margin for your positions. The upside is that you're less likely to get liquidated — more funds are backing the position. The downside is that if liquidation does happen, your entire account could be wiped out.
Example: You have 1,000 USDT in your account and open a BTC long position in cross mode. As losses mount, the system automatically dips into your remaining balance to maintain the position. If the market keeps moving against you, all 1,000 USDT could eventually be lost.
Pros and Cons at a Glance
| Isolated Margin | Cross Margin | |
|---|---|---|
| Maximum loss | Limited to allocated margin | Could be your entire account balance |

| Best for | Experimental trades, high-risk positions | Multi-position hedging, experienced traders |
| Capital efficiency | Lower | Higher |
Which Should Beginners Choose
Beginners should strongly consider using isolated margin. The reason is straightforward: while you're still learning the ropes of futures trading, isolated margin ensures that a single mistake won't wipe out your entire account. Once you've built up enough experience and risk management skills, you can consider switching to cross margin.
How to Switch Modes
On the Binance futures trading page, you'll find an "Isolated/Cross" toggle button near the position information. Just tap to switch. Note: you can switch even while holding positions, but it may affect your liquidation price, so always double-check before making the change. If you don't have an account yet, sign up for Binance to get started.
Risk Warning: Regardless of which margin mode you use, futures trading carries the risk of losing your principal. Choosing a mode is just one piece of risk management — it must be paired with sensible leverage and stop-loss strategies.
