Recently, someone asked me this question again, so today I will clearly explain the difference between full margin and isolated margin.

First, let's talk about what full margin means. Full margin mode means that all available funds in your account can be used as collateral. What is the benefit of doing this? As long as the leverage isn't extremely high, the risk of liquidation is actually quite low. Because of this feature, full margin mode is especially suitable for hedgers, as they need stability.

On the other hand, isolated margin is different. Isolated margin mode allocates a specific amount of collateral to each position, and this money can only be used for that position. If the market moves significantly or leverage is used aggressively, the margin for that position might not be enough to cover unrealized losses, and it will be forcibly liquidated. But the advantage is that your losses are limited to the margin of that position and won't affect your entire account.

Regarding margin types, full margin is also called cross margin, meaning all positions share a single margin pool, and the entire account balance supports these positions. Isolated margin is also called independent margin, where each position's margin is separate and does not affect others.

So, how to choose? My view is that if you are an institution or have been active in this market for many years, full margin mode is indeed more flexible, especially for hedging. But if you are still learning or want to control risk, isolated margin is more suitable because the maximum loss is limited to the amount you allocated for that position, which also reduces psychological pressure. Especially for beginners, it's crucial to understand the risks of full margin; a single mistake could wipe out your entire account.
