Do you know what the most frequently asked question is by someone just starting with derivatives? Margin selection. Especially whether to use isolated or cross margin always comes up in my conversations. Today, I want to explain the difference between these two modes in detail because making the right choice directly affects your profit.

Let's start with isolated mode. Suppose you have $200 in your derivatives wallet. The price of X coin is $1,000, and you open a position with $100 using 10x leverage. In this case, you're making a trade worth $1,000 of coin size, but you're risking only $100. This is where the beauty of isolated mode becomes apparent. Only that $100 is at risk, and the remaining $100 is completely protected.

But everything has a trade-off. In this mode, your liquidation price is close to $900. Why? Because with only $100 margin, you're carrying a position ten times larger. When the coin drops 10%, you lose $100 and the trade closes. But there's also an advantage; in case of sudden volatility or bad news, your entire balance isn't lost, only that $100 position is lost.

Now, let's explain what cross margin is. If you opened the same example in cross mode, the liquidation level would drop to $800. Why? Because here, your entire $200 in the derivatives wallet supports the position. The risk is higher, but the advantage is this: if the coin drops from $1,000 to $850 and then rises to $1,100, you can hold the position without liquidation. In isolated mode, you would be liquidated at $900 and lose $100. In cross mode, you make a $100 profit because the extra balance sustains the position.

The advantages and disadvantages brought by risk become clear here. Cross margin feels more like playing as a trader, with higher risk but also higher flexibility. Isolated mode is disciplined, controlled, with each position independent. If one position suffers a loss, others are unaffected. In cross mode, all positions influence each other.

And let me tell you this; in isolated mode, if you want to move your liquidation level further away, you can add extra margin to that position. But always remember, if risk increases, your chances of avoiding liquidation decrease. Which one you choose depends on your risk tolerance. If you're just starting out, I recommend isolated because it's more predictable.
