Cross-Margin Explained
Arcex utilizes cross margin on most assets
What is cross-margin?
At Arcex, we use a cross-margin system to make managing your account as simple and efficient as possible. Instead of juggling margin for each individual trade, your entire account balance works together to support all of your open positions.
Think of it like this: instead of having separate small savings accounts for each of your monthly bills, you have one large checking account that all your bills are paid from. This gives you more flexibility and security.
One Balance to Rule Them All
With cross-margin, all the USDC in your account is pooled together to act as a single, shared safety net for all your trades. This has a few key advantages:
Simplicity: You don't need to worry about allocating a specific amount of margin to each new position you open.
Flexibility: Profits from one of your winning positions can automatically be used to cover the losses of another, helping you avoid liquidation on that losing position.
Efficiency: You can often open larger positions than you could with an isolated margin system, as the risk is spread across your entire portfolio.
A Practical Example
Let's say you have $2,000 in your account and you open two positions:
A long position on Bitcoin (BTC)
A short position on Ethereum (ETH)
Suddenly, the price of Bitcoin drops, and your BTC position is now at an unrealized loss of -$500. At the same time, the price of Ethereum also drops, and your ETH position has an unrealized profit of +$500.
Isolated Margin
Might get liquidated if the -$500 loss exceeds its dedicated margin.
The +$500 profit is locked to this position and can't help the other.
One position could be closed at a loss, even though your overall account is even.
Cross Margin (Arcex)
The -$500 loss is offset by the profit from the ETH position.
The +$500 profit automatically helps to support the losing BTC position.
Both positions remain open, as your total account balance is unchanged.
As you can see, the cross-margin system provides a more holistic view of your account's health, giving your positions more breathing room and protecting them from being prematurely liquidated.
What to keep in mind
While cross-margin is powerful, it's important to remember that since your entire balance is shared, a single, very large losing position can put your whole account at risk. That's why it's always crucial to manage your risk, use leverage wisely, and keep a close eye on your overall portfolio.
