Isolated Margin
Share post
In Brief
Isolated margin is a trading mode in which a specific amount of collateral is allocated to a single position, containing liquidation risk to that position and protecting the rest of the trader's account.
What Is Isolated Margin?
Isolated margin is a margin mode in leveraged trading where a trader allocates a specific amount of collateral to a single position. If the position is liquidated, only the
allocated margin is lost — the rest of the trader's account balance is untouched.
Isolated margin is the preferred mode for speculative trades, high-leverage positions, and new traders who want to strictly limit their downside per trade.
How Does Isolated Margin Work?
The trader chooses a position size and leverage.
They allocate a specific margin amount — for example, $500 out of a $10,000 account.
The platform uses only that $500 as collateral for the position.
If the market moves against the trader and margin is consumed, the position is liquidated at a predetermined liquidation price.
The remaining $9,500 in the account is unaffected.
Isolated Margin Example
A trader has $10,000 in their account and opens a 50x long BTC position with $500 of isolated margin:
Position size: $25,000 (0.417 BTC at $60,000)
Margin allocated: $500
Liquidation distance: approximately 2% below entry
If BTC drops 2%, only the $500 allocated margin is lost. The remaining $9,500 in the account is untouched and available for other trades.
Isolated vs Cross Margin
| Feature | Isolated Margin | Cross Margin |
|---|---|---|
| Collateral at risk | Allocated margin only | Entire account balance |
| Liquidation scope | Single position | Can cascade across positions |
| Capital efficiency | Lower | Higher |
| Complexity | Simpler | More complex |
| Best for | Speculation, high leverage | Hedged or correlated portfolios |
Advantages of Isolated Margin
Strict loss containment — maximum loss is known in advance
Simpler mental model — each position stands alone
Safer for high-leverage trades — a liquidation does not threaten the rest of the account
Better for beginners — clearer understanding of per-trade risk
Disadvantages of Isolated Margin
Lower capital efficiency — margin must be posted separately for each position
No natural hedging — gains on one position cannot offset losses on another
Faster liquidation — less collateral means less buffer against adverse moves
When to Use Isolated Margin
High-leverage speculative trades (50x+) where strict loss limits are essential
Experimenting with a new market or strategy
Keeping independent risk per trade in a portfolio of unrelated positions
Isolated Margin and Trust Wallet
Trust Wallet users can select isolated margin mode when opening perpetual futures positions on Hyperliquid or Aster DEX. Isolated margin is often the safer choice for high-leverage
trades, since it limits the maximum loss to the collateral allocated to that single position.
