Isolated margin limits the collateral behind a trade to an amount you choose, so a liquidation costs you that amount and no more. Cross margin lets every open position draw on the same shared pool, so a trade has more room to survive, but a losing one can pull down the whole account. Neither mode is safer in every case. The right one depends on how many positions you hold, how much leverage you use and how closely you can watch the account.
This guide explains how each mode works, runs the same trade through both, compares them side by side and gives you a way to pick before you place the order.
TL;DR
- Isolated margin: you assign a fixed amount of collateral to one position. If it is liquidated, that assigned margin is what you lose, and the rest of your balance is normally left alone.
- Cross margin: all eligible funds in the account back all your positions. You get a wider buffer, but one bad trade can put the entire balance at risk.
- Liquidation: isolated liquidation sits closer to your entry at the same leverage. Cross liquidation is further away, but it depends on the whole portfolio, not one trade.
- Exchange rules differ: collateral lists, leverage caps, switching rules and liquidation thresholds change by exchange and even by product, so read the rules for the exact contract you trade.
- Neither mode protects you from bad sizing. Risk per trade still decides how much you can lose.

What cross and isolated margin mean
Margin is the collateral you post to open a leveraged position. Kraken Learn describes leverage as controlling a larger position with less capital. At 10x, one dollar of margin controls a ten-dollar position. It defines collateral as the cash or crypto pledged to secure that exposure, and liquidation as the forced closing of a position when margin falls below the maintenance requirement.
The margin mode answers one question: which of your money stands behind this trade?
Coinbase's help page on margin types gives the clearest short version. Under cross margin, available account or portfolio funds can support losing trades, and gains on one position can offset losses on another. Under isolated margin, you assign a chosen amount to a single position. That position's margin is at risk, and unallocated funds are normally kept separate from it.
That is the whole idea. The consequences are what matter in practice.
How cross margin works
In cross mode, your positions share one pool. On Coinbase, all funds in the Perpetuals portfolio back cross positions. Other exchanges describe the same structure in their own terms:
- Binance says it runs one cross-margin account, shared across your cross positions and the available trading pairs.
- Bitso says cross margin uses one shared collateral pool for all margin trades, and gains in one position can offset losses in another.
- KuCoin says its cross margin uses all assets in the margin account as collateral and treats the account as one position with a shared debt ratio.
Two practical effects follow.
The buffer is bigger. A single position is backed by your whole pool, so a sharp wick against you is less likely to force a close. Kraken's derivatives support notes that effective leverage depends on position size relative to your collateral value. Post a lot of collateral behind a small position and your effective leverage is low, whatever the maximum setting says.
The downside is shared too. Coinbase warns that under cross margin one poorly performing position can put the portfolio at risk of liquidation. Your winners can keep a loser alive. A loser can also drain the margin that was supposed to protect your winners.
Collateral breadth varies by venue. Kraken Pro says its cross margin accepts 48 or more eligible crypto assets, including BTC, ETH, SOL and XRP, subject to its current list. Coinbase's comparison lists USDC plus multi-asset collateral. Check what your exchange accepts, because a pool that holds volatile coins can shrink at the same moment your position moves against you.
How isolated margin works
In isolated mode, you decide how much margin goes into the position. Coinbase's example is a portfolio of 10,000 USDC with 8,000 USDC posted to one isolated position. Only the 8,000 USDC is exposed to that position's liquidation, and the other 2,000 USDC stays outside it. Added margin also becomes exposed, which matters later.
On Binance, isolated margin is independent for each trading pair, you can open several isolated accounts for different pairs, and liquidation of one does not affect the others. Kraken's derivatives support says isolated margin sets aside initial margin for a specific contract and identifies that allocated margin as the funds at risk. It also states an account-wide liquidation exception, so read that exception on any venue you use.
Kraken Learn adds the trade-off: because isolated margin uses only part of your collateral, liquidation generally sits closer to your entry, while your loss can be capped at the collateral deployed for that position.
That cap is the main reason traders choose isolated. You decide the worst case before you click.
The same trade in both modes
Here is a simplified illustration. The numbers are hypothetical and ignore fees, funding and maintenance margin, which all move real liquidation prices. Your exchange's calculator gives the exact figure.
You have $10,000 in a futures account. You want a $20,000 long position in a coin trading at $100.
| Isolated | Cross | |
|---|---|---|
| Collateral behind the trade | $2,000 (you assign it) | Up to the full $10,000 |
| Position size | $20,000 | $20,000 |
| Effective leverage | 10x | 2x |
| Approximate drop that wipes the collateral | About 10% (near $90) | About 50% (near $50) |
| Most you lose if it liquidates | The $2,000 assigned | Potentially the whole $10,000 |
| What happens to the other $8,000 | Untouched | Backs the position, and every other position |
The cross trade looks far safer because the liquidation price is distant. But if the coin falls 40% and you do nothing, you have lost $8,000 of an account you thought was diversified into other positions. In the isolated trade, the same 40% fall would have ended at the 10% mark, with a $2,000 loss and $8,000 intact.
Now notice the reverse. In a fast 12% wick that recovers within the hour, the isolated trade is liquidated and the cross trade survives. Isolated gives you a defined loss. Cross gives you staying power and an undefined one.
You can get a similar loss cap in cross mode with a hard stop-loss and sensible sizing. Without them, cross has no built-in ceiling.
Isolated vs cross margin side by side
| Factor | Isolated margin | Cross margin |
|---|---|---|
| Collateral | Fixed amount per position | Shared pool for all positions |
| Maximum loss on one trade | The margin assigned (plus anything you add) | Potentially the whole pool |
| Liquidation distance at same leverage | Closer to entry | Further from entry |
| Effect of one liquidation | Other isolated positions are unaffected | Can close positions across the account |
| Monitoring | Each position's health | One account-wide margin ratio |
| Gains on one position | Do not support another | Can offset losses elsewhere |
| Best suited to | High-conviction single trades, small tests, defined risk | Hedged or multi-leg portfolios, low effective leverage |
Liquidation and monitoring: where the modes really differ
With isolated margin, you watch each position separately. Coinbase displays a liquidation price for isolated positions as the actual trigger, and the cross price as only an estimate, because the cross figure depends on the rest of your portfolio. That estimate can move when your other positions move.
With cross margin, you watch one ratio for the whole account. A few examples from exchange documentation show how this works:
- Binance calculates cross margin level from total asset value and debt in the cross account, and warns you to add margin or close positions.
- Bitso keeps one account-wide Margin Level rather than one per position, and closes positions across the Margin Wallet at 1.10×.
- Kraken Pro compares aggregate equity with aggregate maintenance margin live, and its liquidation engine closes positions if total equity falls below maintenance.
- KuCoin states a 90% debt ratio triggers a warning and 95% triggers forced liquidation on its margin account.
The pattern matters more than any one threshold. In cross mode, a position you forgot about can become the reason a position you care about gets closed. In isolated mode, you can lose a trade you were not watching, but only that trade.
Market-wide stress makes the difference sharper. When many leveraged positions are forced shut at once, price moves feed on themselves. Our write-up of the October 10 crypto liquidation cascade walks through how that plays out, and why shared collateral can fail quickly in those moments. If you want to follow liquidation activity as it happens, see our comparison of crypto liquidation trackers.
Rules change by exchange and by contract
Margin mode is not a universal standard. The same words can come with different rules.
- Leverage caps. KuCoin states that its cross margin supports up to 5x leverage, with maximum borrowable assets described as up to four times total cross-account assets.
- Spot margin versus derivatives. Kraken Pro uses cross margin for all of its spot-margin trading, pooling your full balance across every open eligible position. Isolated is not an option there. Its derivatives platform is different.
- Switching. Kraken's derivatives support says margin preferences apply per contract, cannot be changed after opening without closing the position, and that cross and isolated positions can coexist on different contracts but not the same one.
- Funding and collateral. Collateral scope, funding treatment and liquidation mechanics can differ even inside one provider.
Before you trade, find these four answers in your exchange's help pages for your exact product: which modes it offers, what counts as collateral, whether you can switch with a position open, and what the liquidation rule is. Also note that US rules and product availability differ from other countries, and some products described in exchange documentation are not offered to US residents. Confirm what is available to you.
Forex and stock margin work differently. Retail brokers usually apply a single account-level margin requirement, which resembles cross margin in practice, and typically do not give you an isolated option per trade. If you also trade forex, our guide to position sizing in forex covers how to size when the account is effectively one pool.
When to use isolated margin, and when to use cross
Start with what you are trying to control.
Choose isolated margin when:
- You want a hard ceiling on what one idea can cost.
- You are testing a new setup, a new coin or a new exchange with small money.
- You use high leverage on a short-term trade. Isolating it keeps a mistake from reaching the rest of your balance.
- You hold several unrelated positions and want one failure not to spread.
- You cannot watch the screen. A defined loss is easier to live with when you are asleep.
Choose cross margin when:
- You run a hedge or a spread, where one leg offsets the other and separate margin would waste collateral.
- Your effective leverage is low, because the position is small relative to the account.
- You can monitor the account-wide ratio and keep stop-losses on every position.
- You mainly want to avoid being liquidated on a brief wick, and you accept the shared risk that comes with that.
A practical rule: if you cannot state, in dollars, the most you could lose on this trade in the current mode, switch to isolated or reduce size until you can. Cross margin with no stop and high size is the combination that empties accounts.
Both modes can also be misused. In isolated mode, topping up margin on a losing position moves your liquidation price further away, but it turns that cushion into more money at risk. Coinbase notes that added margin becomes exposed. Adding margin to hold a trade you would not open again today is a decision worth pausing on.
How to decide before you place the trade
- Set the loss first. Decide the share of your account you will risk on this idea. Our guides on risk per trade and position sizing methods cover how to turn that figure into a size.
- Place the stop where the idea is wrong, not where the margin runs out. A stop should trigger well before liquidation in either mode.
- Calculate leverage from size, not from the slider. The slider is a maximum. What counts is position value divided by the collateral behind it. Our leverage calculation guide shows the arithmetic.
- Pick the mode that matches the loss you set. If the assigned margin equals your intended risk, isolated fits naturally. If the position is small against a large pool, cross can work.
- Check the liquidation price on the exchange for your exact contract and compare it with your stop.
- Write down the rule for adding margin. For example: never add to a losing isolated position. Decide that now, not mid-drawdown.

Our perspective on margin modes
Most traders ask which mode is better. We think the better question is which mode makes your plan easier to follow when you are under stress.
Isolated margin turns risk into a number you chose in advance. That helps people who tend to move stops, add to losers or size up after a win, because the damage has a boundary. Cross margin is a more capable tool, but it rewards a trader who already has rules: fixed risk per trade, stops that actually get used, and a habit of checking the whole account instead of one chart.
At Discipline AI, we look at trading as a decision process, not a prediction contest. A margin mode is a decision about what you are willing to lose, so it belongs in the plan before the entry, next to your stop and your size. We also care about what the evidence says about a setup, including its sample size, and about the times when the best action is to stand aside. Leverage multiplies whichever of those you got right or wrong, and no mode guarantees a profitable trade.
Our view on beginners is simple. Start isolated, keep leverage low, and practice the mechanics with paper trading before real money is involved. Move to cross when you can explain, from your own journal, why a shared pool improves your trades and not just your comfort.

FAQ
Is cross or isolated margin safer?
Isolated margin is safer in the sense that your maximum loss on a position is the margin you assigned, plus anything you add later. Cross margin gives a trade more room to survive, but a bad position can reach your entire pool. Safety also depends on your stops and size, which matter more than the mode.
Can I switch between cross and isolated margin on an open position?
That depends on the exchange and the product. Kraken's derivatives support says margin preferences apply per contract and cannot be changed without closing the position. Check the help page for your exact contract before you rely on switching mid-trade.
Does isolated margin mean I can never lose more than the margin?
Not always. Exchange terms can include exceptions, and Kraken Pro warns that spot-margin users may lose more than their initial investment and remain responsible for a deficiency after liquidation. Read the liquidation and negative-balance terms for your product. Fast markets can also close a position at a worse price than the one you saw.
Why is my liquidation price different in cross mode?
Cross liquidation depends on the whole account, so the price shifts as your balance, other positions and prices change. Coinbase shows the cross figure as an estimate and the isolated figure as the actual trigger. Add or remove an unrelated position and the estimate for your first trade can change.
Which mode should a beginner use?
Most beginners are better served by isolated margin at low leverage, because the loss on any trade has a clear limit. Practice in a paper trading environment first so you can see how liquidation levels behave. Move to cross only when you have fixed risk rules and use stops every time.
