When you open a perpetual position on Hyperliquid, you’ll notice two options in the top-right corner of the interface: Cross and Isolated. Most beginners leave it on whatever the default is and never think about it again. That’s a mistake — because the choice between cross and isolated margin determines how much of your account is at risk if a trade goes wrong, and it directly affects your liquidation price on every position you hold.
This guide explains both modes in plain English, with real dollar examples showing exactly what happens at liquidation under each one. By the end you’ll have a clear decision rule: use cross for this situation, isolated for that one — no ambiguity.
Cross Margin — How It Works
In cross margin mode, your entire available account balance acts as margin for every open position. All your positions share one common pool of collateral. When one position starts losing, Hyperliquid automatically draws from your available balance to keep it alive — right up until the entire account is exhausted.
📊 Cross Margin — Worked Example
You have a $1,000 USDC account on Hyperliquid set to Cross margin. You open a BTC long at $62,000 with 10x leverage. The position size is $1,000 worth of BTC (using the full account as collateral pool).
Account balance: $1,000 USDC
BTC entry price: $62,000
Position size: $1,000 notional (10x)
Margin mode: Cross
Liquidation price: ~$56,400 (approx. 9.1% below entry)
— Hyperliquid uses your full $1,000 as buffer
— Price must fall ~9% before liquidation triggers
— BUT if it liquidates, you lose your ENTIRE $1,000 account
BTC entry price: $62,000
Position size: $1,000 notional (10x)
Margin mode: Cross
Liquidation price: ~$56,400 (approx. 9.1% below entry)
— Hyperliquid uses your full $1,000 as buffer
— Price must fall ~9% before liquidation triggers
— BUT if it liquidates, you lose your ENTIRE $1,000 account
The defining characteristic of cross margin: a lower liquidation price, but higher total exposure. Because the full balance backs the position, the platform can absorb more adverse movement before liquidating. The tradeoff is that a liquidation wipes everything — not just the margin allocated to that trade.
The cascade risk: In cross margin, if you have three open positions and one gets liquidated, the liquidation engine doesn’t just close that one trade. It can pull margin from your entire account — including from the margin backing your other two positions — to try to cover the loss. In extreme market conditions, one bad position in cross mode can cascade and liquidate all of them.
Isolated Margin — How It Works
In isolated margin mode, you assign a specific amount of USDC as the margin for each individual position. That amount is ring-fenced — it’s all the platform can use for that trade. If the position is liquidated, you lose only the assigned margin, and the rest of your account is completely untouched.
📊 Isolated Margin — Same Scenario
Same $1,000 account, same BTC long at $62,000 with 10x leverage. But this time you assign only $100 as isolated margin for this position.
Account balance: $1,000 USDC
Isolated margin: $100 assigned to this trade
Position size: $1,000 notional (10x on $100)
Margin mode: Isolated
Liquidation price: ~$61,370 (approx. 1% below entry)
— Only $100 backs this position
— Liquidation triggers much closer to entry
— BUT if liquidated, you lose $100 max — $900 is untouched
Isolated margin: $100 assigned to this trade
Position size: $1,000 notional (10x on $100)
Margin mode: Isolated
Liquidation price: ~$61,370 (approx. 1% below entry)
— Only $100 backs this position
— Liquidation triggers much closer to entry
— BUT if liquidated, you lose $100 max — $900 is untouched
The defining characteristic of isolated margin: a higher liquidation price (closer to entry), but capped maximum loss. The position has less buffer before liquidation because only the assigned margin backs it. But no matter what happens — a flash crash, a manipulation event, a gap — the most you can lose on that trade is the isolated margin amount. Everything else in your account is protected.
Adding margin in isolated mode: On Hyperliquid, you can manually add more margin to an isolated position after it’s open — this moves the liquidation price further away, giving the trade more room. You can also remove margin from a winning position to free up capital. This gives isolated mode more flexibility than it might first appear.
Liquidation Price Comparison — Same Trade, Both Modes
This table shows the same BTC long at $62,000 with 10x leverage on a $1,000 account — in both margin modes, at three different isolated margin allocations.
The key insight from this table: More isolated margin = lower liquidation price = more room for the trade to breathe. Less isolated margin = higher liquidation price = tighter stop. The practical solution is to set isolated margin to match where your stop-loss should logically sit — enough margin to keep the position alive until your stop triggers, but no more.
How to Switch Between Cross and Isolated on Hyperliquid
Hyperliquid makes this straightforward — the toggle is always visible in the trading interface.
The Decision Framework — Which Should You Use?
Here is the straightforward rule. It covers 95% of situations:
✅ Use Isolated When…
— You’re holding multiple positions at once and want them independent
— You’re trading a volatile altcoin (XPL, TIA, AI coins, memecoins)
— You’re testing a new setup or trading a new market you don’t know well
— You’re away from the screen and want a hard max-loss cap
— You’re a beginner — isolated protects you from yourself
— The trade is a speculative punt with a wide stop or uncertain setup
— You want to use higher leverage without risking the whole account
— You’re trading a volatile altcoin (XPL, TIA, AI coins, memecoins)
— You’re testing a new setup or trading a new market you don’t know well
— You’re away from the screen and want a hard max-loss cap
— You’re a beginner — isolated protects you from yourself
— The trade is a speculative punt with a wide stop or uncertain setup
— You want to use higher leverage without risking the whole account
⚡ Use Cross When…
— You’re trading a single position with your full account conviction
— You’re trading BTC or ETH with a wide structural stop and need room
— You’re an experienced trader who actively monitors positions
— You’re running a bot that closes positions via stop-loss before liquidation
— You want the lowest possible liquidation price on one large trade
— You’re hedging — holding opposing positions that partially cancel each other
— You’re trading BTC or ETH with a wide structural stop and need room
— You’re an experienced trader who actively monitors positions
— You’re running a bot that closes positions via stop-loss before liquidation
— You want the lowest possible liquidation price on one large trade
— You’re hedging — holding opposing positions that partially cancel each other
The Simple Rule for Beginners
Start every trade in Isolated mode.
Switch to Cross only when you have a specific reason to.
Switch to Cross only when you have a specific reason to.
Isolated is the defensive default. You can always switch to cross as you get more experienced — the other direction is harder to undo.
What Is “Unified” on Hyperliquid?
You’ll notice a third option in the Hyperliquid interface alongside Cross and Isolated: Unified. This is Hyperliquid’s account-level mode that allows your entire portfolio — spot holdings, perp positions, and USDC balance — to contribute to your margin in a single unified account. In unified mode, if you hold BTC spot, that BTC value can act as collateral for your perp positions without converting it to USDC first.
For most traders starting out, stick with the standard non-unified account — it’s simpler to understand your margin requirements and liquidation prices. Unified accounts are for more experienced users who actively manage a portfolio of spot and perp positions together.

The Bottom Line
Cross margin gives you a lower liquidation price and more room for your trade to breathe — but one bad position can drain your entire account. Isolated margin caps your loss at whatever you assign, protects everything else, and is the right default for most traders on most trades.
The practical setup: use isolated margin as your default, assign margin that gives your stop-loss room to trigger before the liquidation price, and only move to cross when you have a specific reason — a single high-conviction trade, a hedged position, or a bot that manages stops automatically. Combined with a proper stop-loss (and ideally a trailing stop), isolated margin gives you two independent layers of downside protection on every trade you make on Hyperliquid.

I run all my altcoin and memecoin positions in isolated margin. For BTC with a wide structural stop, I’ll use cross — but only when I’m watching it closely. The default for anyone who isn’t glued to the screen should be isolated every time. It’s the one setting that prevents a single bad trade from ending your session entirely. Set it once, make it your habit.
