Isolated vs Cross Margin: What's the Real Difference?

Isolated margin locks a fixed, pre-set amount of margin to one specific position. If that position gets liquidated, you only lose the amount you allocated to it — the rest of your account balance is never touched.

Cross margin works differently: it shares your entire account balance as margin across all your open positions. If a position starts losing, the exchange can draw on your whole balance to keep it alive longer and delay liquidation.

That flexibility comes with a tradeoff. Under cross margin, a big enough loss doesn't just wipe out one position — it can put your entire account at risk.

This is much easier to see with actual dollar figures than with definitions alone.

Say you're trading with a $1,000 account. You open a position and allocate $100 to it as isolated margin. If that position gets liquidated, you lose exactly $100 — the remaining $900 stays untouched and available for other trades.

Now open the same position under cross margin. If price moves against you, the exchange can pull from the full $1,000 to keep the position open longer. That can buy you time, but it also means a large enough adverse move puts the entire $1,000 at risk — not just the $100 you originally intended to risk.

If you're new to leveraged trading, or you're taking a higher-leverage, higher-risk bet, isolated margin is generally the safer choice. It caps your maximum possible loss on that one trade before you even enter it.

Because the rest of your account is protected no matter what happens to that position, one bad trade can never take down your whole balance. That's why isolated margin is usually the recommended default for beginners.

Cross margin tends to appeal to more experienced traders who are actively managing several positions at once and want their full balance acting as a buffer against short-term volatility on any single one of them.

That flexibility comes at the cost of more active risk management. A string of losses draws down your entire account rather than staying contained to one position, so you need to keep a close eye on total exposure across everything you're holding.

If you're newer to leverage or futures, isolated margin is usually the safer default — it puts a hard ceiling on what any single trade can cost you.

Save cross margin for situations where you have a specific reason to want it and fully understand the tradeoff involved. And this is exactly the kind of setting worth testing in a calculator before real money is on the line.

Margin mode is a risk-management setting, not a profit setting. It determines how much of your account is exposed to a single bad trade — not how much you stand to earn.

Choosing it intentionally, instead of just going with whatever the exchange defaults to, is a simple, free way to keep your risk under control.
