Margin trading is the practice of using borrowed funds to trade a larger position than your account balance would otherwise allow. Your own capital serves as margin — collateral that secures the borrowed exposure. If the trade moves in your favor, returns are amplified. If it moves against you, losses are amplified too, and you risk liquidation.

How Margin Trading Works

When you open a margin trade, you deposit collateral (margin) and select a leverage level. The exchange effectively extends your buying power by the leverage multiplier.

For example, with $2,000 in margin and 5x leverage, you can open a $10,000 position. You're putting up 20% of the total position value as collateral, and the remaining 80% is effectively borrowed exposure.

Your profit and loss are calculated on the full $10,000 position, not your $2,000 margin. A 10% favorable move yields $1,000 in profit — a 50% return on your margin. A 10% adverse move costs $1,000 — wiping out half your collateral.

Isolated Margin vs. Cross Margin

Most crypto trading platforms offer two margin modes, and understanding the difference is critical for managing risk.

Isolated Margin

In isolated margin mode, each position has its own dedicated pool of margin. Only the margin assigned to a specific position is at risk if that position gets liquidated.

Advantages:

• Risk is contained — a liquidation on one position doesn't affect your other positions or remaining account balance
• Easier to manage risk on a per-trade basis
• Ideal for higher-risk, speculative trades where you want to cap your maximum loss

Disadvantages:

• Each position must be individually capitalized
• Liquidation price is closer to your entry (less margin backing the position)
• You may need to manually add margin to prevent liquidation

Cross Margin

In cross margin mode, all positions share a single margin pool — your entire available account balance. If one position is losing, it can draw margin from your full balance to avoid liquidation.

Advantages:

• Liquidation price is pushed further away because the entire account balance serves as collateral
• Unrealized profits from one position can help support another position
• More capital-efficient for traders running multiple positions

Disadvantages:

• A single bad trade can drain your entire account — not just the margin allocated to that position
• Harder to isolate risk per trade
• Cascading liquidations are possible if one position moves sharply against you and depletes the shared margin pool

Which Margin Mode Should You Use?

The choice depends on your trading style and risk tolerance:

| Scenario | Recommended Mode | | ------------------------------- | ---------------- | | Single focused trade | Isolated | | Experimental or high-risk setup | Isolated | | Multiple correlated positions | Cross | | Portfolio-level risk management | Cross | | New to margin trading | Isolated |

Many experienced traders default to isolated margin for individual trades and use cross margin only when they have a coordinated portfolio strategy. The safety of knowing exactly how much you can lose on each trade is worth the reduced capital efficiency.

Margin Requirements

Two key thresholds govern your positions:

• Initial margin — the minimum collateral to open a position. At 10x leverage, this is 10% of the position value. You can't open the trade without meeting this requirement.
• Maintenance margin — the minimum collateral to keep the position open. This is lower than the initial margin (often 0.5%–2%). If your margin balance drops to this level due to unrealized losses, your position is liquidated.

The gap between initial and maintenance margin gives your trade a buffer zone. The larger this buffer, the more room the position has to absorb adverse price movements before liquidation triggers.

Risks of Margin Trading

Margin trading introduces risks that don't exist in spot trading:

• Amplified losses — leverage magnifies losses in the same proportion as gains
• Liquidation — losing your entire margin if the trade moves too far against you
• Funding costs — holding leveraged positions over time incurs periodic funding rate payments
• Margin calls — in some systems, you're notified to add margin before liquidation; in crypto, liquidation often happens automatically without warning
• Overexposure — the ease of taking large positions can lead to taking on more risk than intended

Margin Trading in Competitive Environments

On platforms like Legend, margin mode selection is a strategic decision in competitive trading. Using isolated margin in a duel means your maximum loss is capped and predictable. Using cross margin gives more liquidation buffer but puts more capital at risk. Top competitive traders understand both modes deeply and choose based on the specific situation — asset volatility, position size, and how much of their account they're willing to risk on a single contest.

Margin trading is a powerful capability, but it demands respect. Master the mechanics of isolated and cross margin, understand your liquidation prices, and always know your maximum downside before entering a trade.
