    Overview

    تحذير المخاطر Margin trading with leverage carries significant risk. Both isolated and cross margin can result in the loss of your deposited funds. This guide is for educational purposes only and is not financial advice.

    عندما تفتح مركزًا برافعة على أي منصّة كريبتو كبرى، أحد أول الخيارات التي تتّخذها هو اختيار وضع هامشك: معزول أو متقاطع. هذا الإعداد يغيّر جوهريًا كيف يُدار ضمانك وكم يمكنك خسارته.

    فكّر فيه هكذا: الهامش المعزول كوضع المال في مظاريف منفصلة لكل صفقة — إن نفد مظروف، الأخرى دون مساس. الهامش المتقاطع كإبقاء كل مالك في محفظة واحدة — أي صفقة يمكنها السحب من كامل الرصيد.

    اختيار الوضع الصحيح حاسم لـإدارة المخاطر في التداول بالرافعة. لنفصّل كيف يعمل كل منهما.

    What Is Isolated Margin?

    ✓ How It Works

    1. You allocate a fixed margin amount to a single position (e.g., $1,000). 2. You select leverage (e.g., 10x), giving a notional position size of $10,000. 3. Only that allocated margin — not your full account — backs the trade. 4. If price moves against you, losses are capped at the assigned margin plus any manual top-ups. 5. Liquidation triggers when equity on that position falls below the maintenance margin requirement (typically 0.4%–0.5% of notional on Binance and Bybit for BTC perps, scaling up with position size).

    ✓ Key Characteristics

    • Loss is ring-fenced to the margin assigned to that position. • Each position has its own liquidation price, calculated independently. • Liquidation price sits closer to entry than in cross mode. • You can manually add margin to push the liquidation price further away. • Risk per trade is easy to size — max loss ≈ assigned margin minus liquidation fees. • Funding payments (on perpetuals) are still deducted from the position's margin every 8 hours on most venues.

    الخلاصة الأساسية 💡 Example: You have $10,000 in your account and open a long BTC position with $1,000 margin at 10x leverage ($10,000 position). If BTC drops enough to liquidate you, you lose only the $1,000 — your remaining $9,000 is safe.

    What Is Cross Margin?

    ✓ How It Works

    1. Your entire available balance in the margin wallet acts as collateral. 2. All open positions share that collateral pool. 3. Unrealized profit on one position offsets unrealized loss on another in real time. 4. Liquidation only triggers when total account equity falls below the aggregate maintenance margin of all open positions. 5. When liquidation does occur, the engine can close any or all positions to restore the maintenance margin — not just the one underwater.

    ✓ Key Characteristics

    • A single bad trade can drain the whole margin balance if other positions don't offset it. • Positions share collateral, so liquidation prices are further from entry on each individual trade. • Useful for hedged or delta-neutral books (e.g., long BTC perp / short ETH perp) where PnL nets out. • Funding fees from all positions are debited from the same pool. • Most venues let you toggle a sub-account or 'isolated wallet' inside cross mode to wall off specific strategies.

    Liquidation Examples

    ✓ Isolated Margin Scenario (worked example)

    Account balance: $10,000. Long BTC/USDT perp at $60,000 entry. Isolated margin: $1,000 at 10x leverage → notional $10,000, position size 0.1667 BTC. Maintenance margin rate (MMR): 0.5%. Liquidation price ≈ Entry × (1 − 1/Leverage + MMR) = 60,000 × (1 − 0.10 + 0.005) = $54,300. So liquidation hits at roughly a 9.5% drop, not a full 10% — and arrives sooner once you factor in funding payments and the liquidation fee (~0.5%–1.5% of notional on Binance/Bybit). Result: you lose the $1,000 isolated margin. The remaining $9,000 in the account is untouched and still available for other trades. Note that exchanges use the mark price (an index-based fair value), not the last traded price, to trigger liquidation — this prevents wick liquidations on thin order books.

    ✓ Cross Margin Scenario (worked example)

    Same setup: $10,000 balance, long 0.1667 BTC at $60,000, but in cross mode the full $10,000 backs the position. Effective leverage on the position is 1x ($10,000 collateral vs $10,000 notional). Liquidation price ≈ 60,000 × (1 − 1 + 0.005) ≈ $300 — i.e., BTC would have to fall ~99.5% before this single position liquidates. In practice, you'd open multiple positions, and liquidation triggers when total equity < sum of maintenance margins across all of them. Trade-off: a single position is far harder to liquidate, but if a tail event does push you there (e.g., a Luna-style 99% collapse on a held altcoin perp), the liquidation engine can close every position in the account, not just the losing one. Cross mode also means correlated drawdowns — a sharp ETH/BTC sell-off — can liquidate several positions at once because the shared collateral runs out.

    When to Use Each Mode

    ✓ Isolated Margin: typical use cases

    • Sizing a single directional bet on a volatile altcoin perp without risking the rest of the account. • Testing a new strategy with strict, pre-defined max loss. • Trading low-liquidity pairs prone to wicks (mark-price liquidation still applies, but capped downside helps). • Beginners learning how leverage, funding, and liquidation interact. Exchange notes: Binance USD-M Futures lets you set isolated mode per symbol (one direction at a time, or per long/short in Hedge Mode). Bybit USDT Perp supports both per-position isolated and cross under its Unified Trading Account, and you can switch on a per-symbol basis. offers isolated, cross, and a 'Portfolio Margin' tier that uses risk-based offset for advanced accounts. Hyperliquid defaults to cross but exposes per-position isolated margin via the order ticket — adjustable after entry.

    ✓ Cross Margin: typical use cases

    • Hedged books where long and short legs offset (basis trades, pair trades, delta-neutral funding farms). • Holding multiple correlated positions where you want shared collateral to absorb noise. • Experienced traders running tight, monitored risk who prefer fewer manual margin top-ups. Exchange notes: Binance's Portfolio Margin (separate product, requires ~$100k+ equity and approval) goes further than standard cross — it nets risk across spot, margin, and futures using a SPAN-style model, lowering margin requirements on hedged positions. The Unified Account on Bybit offers similar cross-product netting at lower thresholds. Hyperliquid's cross mode shares collateral across all perps in the account; there is no separate spot margin to net against. Across all four venues, switching modes typically requires the position (or all positions, on some venues) to be flat.

    الأسئلة الشائعة

    What is the difference between isolated and cross margin?
    In isolated margin, only the margin you assign to a specific position is at risk. In cross margin, your entire available balance is shared across all open positions and can be used to prevent liquidation.
    Which margin mode is safer for beginners?
    Isolated margin is generally considered safer for beginners because your maximum loss is limited to the margin allocated to that specific position. Cross margin can drain your entire account balance to cover a losing trade.
    Can I switch between isolated and cross margin?
    Yes, most exchanges (including Binance) allow you to switch margin modes before opening a position. Some exchanges also allow switching on open positions, but this varies. Always check before opening a trade.
    Does margin mode affect trading fees?
    No, margin mode does not affect trading fees. Fees are determined by your position size, order type (maker vs taker), and your fee tier on the exchange. Both isolated and cross margin use the same fee structure.
    What happens when I get liquidated in cross margin?
    In cross margin, the exchange uses your entire available balance to maintain the position. If the market moves far enough against you, your entire account balance (not just the initial margin) can be lost to liquidation.
    Can I use isolated and cross margin at the same time?
    On most exchanges, you set margin mode per trading pair. So you could use isolated margin for BTC/USDC and cross margin for ETH/USDC simultaneously. However, you can't use both modes on the same pair at the same time.
    Which margin mode do professional traders use?
    Professional traders often use cross margin because it's more capital-efficient and reduces the chance of individual position liquidations during normal market volatility. However, they combine it with strict risk management, stop-losses, and position sizing rules.
