Your phone keeps ringing nonstop, and a friend who trades contracts is getting frantic, sending multiple voice messages: "What's going on? Using 3600U full margin 10x long, only a 3% pullback, and the account is wiped out?"

After reviewing his trading records, I understood—he went all-in with 3420U in a single trade, and didn't set a stop-loss at all. This is a classic case of failed position management.

Many people are deceived by the concept of "full margin," thinking it's a risk-averse tool, but in reality, it's quite the opposite. Misusing full margin can lead to liquidation much faster than using isolated positions.

**The truth about full margin liquidation: it's not about leverage, but about position size**

Let's look at specific numbers:

Trading with 3600U capital using contracts, two ways to open positions:

• Using 3240U with 10x leverage (90% of capital), a 5% adverse move wipes out the account
• Using 360U with 10x leverage (10% of capital), it takes a 50% adverse move to liquidate

The difference is clear—this friend put 95% of his capital into one position. When leverage is amplified, even a normal market correction can instantly wipe out the account.

**3 Rules to Stay Alive**

1. **Single position no more than 20% of total funds**

With a 3600U account, invest at most 720U at once. Even if you get the direction wrong and hit stop-loss, you only lose 72U, staying within your capital limits. For volatile contracts like BTCUSDT, a 20U trial fund can still earn 36U, allowing for a quick comeback.

2. **Limit single-loss to 3% of total margin**

Using 720U with 10x leverage, set a 1.5% stop-loss, risking at most 108U—exactly 3% of total funds. Even a few wrong trades won't wipe you out.

3. **Observe sideways markets, do not add to profits**

Only trade breakout opportunities; avoid trading in choppy markets, no chasing after prices post-entry. This helps prevent emotional trading.

**The true value of full margin: a buffer mechanism, not a gambling tool**

The original design of full margin trading was to provide room for market fluctuations. But this requires combining light position sizing for trial trades and strict risk control.

There was a trader who kept getting liquidated every month, but after following these 3 rules, he turned 5000U into 8000U in three months. Someone else used 2000U to grow their account close to 10,000U. He summarized: "I used to treat full margin as gambling, but now I realize, full margin is actually for safer trading."

Many can make money in crypto markets, but few can survive long. The market tests not who earns fast, but who can stay steady until the end.

Manage your positions well, protect your capital—slow is fast. Opportunities are always there; as long as you have bullets, there's always a chance to turn things around.
