BeaconWhat Is Ký Quỹ in Giao Dịch Crypto?
Margin is the collateral you put up to open a leveraged position in perpetual futures trading. When you trade with leverage, you are borrowing against your margin to control a larger position. The margin mode you choose - cross or isolated - determines how that collateral is allocated and what happens when a trade moves against you.
Choosing the right chế độ ký quỹ is one of the most important decisions you make before opening a vị thế. It directly affects your giá thanh lý, your maximum potential loss, and how efficiently you use your capital. Both modes have legitimate use cases, and most experienced traders use both depending on the situation.
Ký Quỹ Chéo Explained
In cross margin mode, your entire available account balance serves as collateral for all of your open positions. If one position starts losing money, it can draw from the unused margin in your account to avoid liquidation. This means your positions have access to more collateral than what was initially assigned to them.
The primary advantage of ký quỹ chéo is capital efficiency. Because all vị thế share the same pool of collateral, you need less total ký quỹ to maintain multiple vị thế. Profitable vị thế can effectively subsidize losing ones, reducing the chance of any single vị thế being bị thanh lý.
The downside is risk concentration. If one vị thế experiences a large adverse move, it can consume ký quỹ from your entire account, potentially triggering thanh lý across multiple vị thế. In the worst case, a single bad trade in chế độ ký quỹ chéo can wipe out your entire account balance.
Ký Quỹ Cách Ly Explained
In chế độ ký quỹ cách ly, each vị thế has its own dedicated ký quỹ that is completely separate from your other vị thế and your remaining account balance. If a vị thế is bị thanh lý, you lose only the ký quỹ assigned to that specific trade - the rest of your account remains untouched.
This makes ký quỹ cách ly ideal for quản lý rủi ro. You know exactly how much you can lose on each trade before you open it. It is essentially a built-in cắt lỗ mechanism at the vị thế level. If you assign $100 of ký quỹ cách ly to a trade, that $100 is the maximum you can lose on that vị thế, regardless of how far the price moves against you.
The trade-off is that isolated vị thế have tighter giá thanh lýs compared to ký quỹ chéo vị thế of the same size. Because the vị thế can only draw from its dedicated ký quỹ, even temporary price spikes can trigger thanh lý if the ký quỹ is insufficient. You may need to monitor isolated vị thế more actively and add ký quỹ if the price moves unfavorably.

Khi Nào Sử Dụng Mỗi Chế Độ
Use cross margin when: You are running multiple correlated positions (like a hedged portfolio), you want maximum capital efficiency, you are comfortable with advanced risk management, or you are confident in your directional thesis and want a wider margin of safety before liquidation.
Use isolated margin when: You are taking a speculative trade with defined risk, you are trying a new strategy and want to limit exposure, you are trading volatile assets where price can spike unpredictably, or you want to be absolutely sure that one bad trade cannot affect the rest of your portfolio.
Many professional traders use a hybrid approach. They keep their core positions in cross margin mode for capital efficiency and use isolated margin for smaller, higher-risk trades. This way, their main portfolio benefits from shared collateral while individual speculative bets are contained.
