Isolated vs Cross Margin: Which One Liquidates You First

Isolated vs cross margin comes down to one question: how much of your account stands behind the trade. In isolated mode, only the margin you assign to the position backs it, so it liquidates first but can cost you at most that margin. In cross mode, your whole wallet backs the trade, so the liquidation price sits further away, but when it hits you can lose the entire balance.

That is why isolated liquidates you first on the same position, and why cross is not "safer". It only moves the cliff further out. The rest of this guide shows the difference with a worked example, then lays the same levels over a real BTCUSDT chart. Exchange rules below come from the Binance and Bybit help centers, checked on 13 Oct 2026. Formulas differ per exchange and change over time, so treat every number here as a model, not a quote from your platform.

How isolated margin works

In isolated mode, each position carries its own margin. Bybit describes it this way: each position is managed independently, with its own allocated margin, and liquidation occurs when the mark price reaches the position's liquidation price. Liquidation of one position does not affect the others.

Binance says the same for hedge-mode positions: if long and short positions on one symbol are isolated, they have separate liquidation prices that depend on the margin allocated to each.

You can add margin to a live isolated position to push its liquidation price away. On Binance this is the Edit icon in the Positions tab, and the added margin comes from your wallet balance. The cost of that move is that you are now putting more of the account behind one trade.

How cross margin works

In cross mode, positions share one pool of collateral. Binance's help center says cross mode shares your margin balance across all open positions on the same type of asset, so USDT-margined contracts draw on the same USDT balance and BTC-margined contracts on the same BTC.

The practical effect is that a loss on one position eats the margin that backs every other position. A winner can carry a loser for a while, and the account is liquidated only when the shared margin runs out. Binance defines the margin ratio as maintenance margin divided by margin balance, and liquidation comes when it reaches 100%. Bybit's cross mode uses the same idea: liquidation triggers when the account maintenance margin rate reaches 100%.

The figure is the same 1,000 USDT account in both modes. Isolated puts 500 on the trade and leaves 500 outside it. Cross puts all 1,000 behind it.

Isolated vs cross margin on the same trade

Here is a worked example. All numbers are made up. It ignores fees and maintenance margin so the arithmetic stays visible.

• Account: 1,000 USDT.
• Position: a long with 10,000 USDT notional, entered at a price of 100. That is 100 units.
• Isolated: you assign 500 USDT of margin. That is 20x on the trade.
• Cross: all 1,000 USDT backs the trade.

A long loses 100 USDT for every 1 point the price falls (100 units). In isolated mode, 500 USDT of margin is gone after a 5-point fall, at a price of 95. In cross mode, 1,000 USDT is gone after a 10-point fall, at a price of 90.

Read the table row by row.

1. Margin on the trade. 500 in isolated, 1,000 in cross.
2. Liquidation price. 95 in isolated, 90 in cross. Isolated is hit first.
3. Drop to liquidation. 5% against 10%.
4. Amount lost. 500 against 1,000.
5. Left in the wallet. 500 in isolated, nothing in cross.

Same position, same size, same entry. The only change is how much margin stands behind it. Cross gave the trade twice the room and risked twice the money.

Real exchanges liquidate a little earlier than this model, because maintenance margin and closing fees take a slice of the margin first. Bybit's isolated-mode formula includes both, and notes that minor differences from the actual liquidation price may arise from closing fees. Use the liquidation price calculator to see the level for your own size and leverage.

Margin mode does not change your stop

A stop-loss sits well inside either liquidation price. If your stop fills at 98 in the example, you lose 200 USDT in both modes. The margin mode only decides what happens when the stop fails to fill: a gap, a fast wick through a thin book, or no stop at all. For how each stop type fills, see order types on crypto futures.

That is the right way to think about it. Size the position from the stop distance, as in the position size calculator, and choose the margin mode for the worst case. Isolated caps the worst case at the assigned margin. Cross leaves the whole account in play.

What the exchanges say, side by side

• Scope. Binance says switching the margin mode only applies to the selected contract. Bybit's Unified Trading Account applies the selected mode to the entire account, so you cannot mix modes per pair there. For how Bybit's and OKX's account modes compare, see Bybit vs OKX.
• Default. Both use cross by default.
• Switching. Binance does not allow a switch while you have open orders or positions on that contract. Bybit allows a switch under conditions, for example enough assets to cover the increased margin and a mark price that is not worse than the liquidation price after the switch.
• Trigger. In Bybit's isolated mode, liquidation triggers when the mark price reaches the liquidation price, and the displayed liquidation price is the actual trigger. In cross mode, the trigger is the account maintenance margin rate reaching 100%, and Bybit says the displayed liquidation price is an estimate and reference only.
• Auto margin. Bybit lists auto margin replenishment as supported in isolated mode and not in cross mode.
• Price used. Both exchanges liquidate on the mark price, not the last price, so a wick on your chart is not the same event. See mark price vs last price.

Bybit gives a worked example for adding margin in isolated mode: a long of 1 BTC at 40,000 USDT with 50x leverage, with 3,000 USDT of extra margin added, a 0.5% maintenance margin rate and a 0.055% taker fee. Its formula gives a liquidation price of 36,380.25 USDT. That is the model for the "add margin to move liquidation away" move. Check the arithmetic yourself: 40,000 − 800 − 3,000 ÷ (1 − 0.00055) = 36,198.35, and 36,198.35 ÷ 0.995 = 36,380.25.

How it looks on a real chart

The chart below is a hypothetical, not a trade anyone took. It uses real BTCUSDT 4-hour candles from Binance spot klines, 6 to 10 Oct 2026, and the same 1,000 USDT, 10,000 USDT notional example as above, with a long entered at the open of the 7 Oct 00:00 UTC candle, 85,550.

1. Isolated level. 5% below entry is 81,272. The candle for 8 Oct 12:00 UTC traded down to 80,914 and the candle after it to 80,394, about 6.0% under entry. In isolated mode with 500 USDT assigned, this position is gone.
2. Cross level. 10% below entry is 76,995. Price never came close in this window, so the position survives, with an unrealized loss of roughly 600 USDT at the low (0.1169 BTC × 5,156).

Two cautions. First, real liquidation uses the mark price, and this chart shows spot candles, so the true trigger can differ by some distance. Second, nothing here says price should have gone one way or the other. The chart only shows how the same fall lands on two different margin setups.

The cross trader in this hypothetical held on and kept the account. A different week, with a deeper fall, would have taken all 1,000. Neither outcome tells you which mode is better.

Which one to use

There is no universal answer, but a few rules hold up.

• Isolated fits a single directional trade where you know the most you are willing to lose. It also fits high leverage on a small slice of the account.
• Cross fits hedged or paired positions and low effective leverage, where you want the account to absorb noise.
• Isolated with a manual top-up lets you choose a liquidation distance, but every top-up is a decision to risk more on the same idea.
• If you hold several positions in cross, one bad trade can take down the others. Count your total exposure, not the single trade.

For the mechanics behind these levels, read mark price vs last price, the exchange comparison in Binance vs Bybit for futures, and how fees move your break-even in risk-reward ratio and break-even. More guides are in the Learn ICT section.

Common mistakes

• Treating cross as lower risk. It lowers the chance of a liquidation on that one trade and raises the amount you can lose.
• Opening a trade in cross by default, because the exchange set it that way, without checking.
• Adding margin to a losing isolated position over and over until it is the same as cross, with no plan.
• Reading the liquidation level off a last-price chart and ignoring that the mark price decides.
• Running several positions in cross and forgetting that they share one pool.
• Assuming the numbers from one exchange apply on another. Margin rules, tiers and formulas differ.

FAQ

Which liquidates first, isolated or cross margin? Isolated, on the same position size and entry. Only the margin you assigned backs the trade, so the liquidation price sits closer to entry. Cross is further away because the whole wallet backs the trade.

Is cross margin safer than isolated? It makes a liquidation on one trade less likely, but when it happens you can lose the entire balance. Isolated caps the loss at the assigned margin.

Can I switch between isolated and cross margin with an open position? On Binance Futures, no: you cannot change the mode while you have open orders or positions on that contract. Bybit allows it under conditions, such as having enough assets to cover the new margin requirement.

Does isolated margin protect my other positions? Yes. Bybit states that liquidation of one isolated position does not affect the others, and Binance gives separate liquidation prices to isolated positions.
