A friend asked me the day before yesterday: "I have 10,000 USDT in full position with 10x leverage, and it only dropped 3% before liquidation. Why is it so fragile?" When I checked his position history, I realized—he went all-in with 9,500 USDT without even setting a stop-loss.

Many traders fall into a misconception that "full position" means strong risk resistance, but in fact, it's the opposite. Misusing full positions often leads to quicker ruin than incremental positions.

**Position size is the fundamental reason for liquidation**

Compare it with a 1,000 USDT account for clarity: using 900 USDT with 10x leverage, a 5% adverse move wipes it out instantly; but if you only invest 100 USDT with 10x leverage, you'd need a 50% adverse move to be liquidated. My friend put 95% of his capital into a position with 10x leverage, so a slight pullback wiped him out completely.

**Three ironclad rules to significantly improve trading stability**

**Rule 1: Limit single position size to within 20% of total funds**

For example, with a 10,000 USDT account, never invest more than 2,000 USDT in a single trade. Even if you’re wrong and stop out with a 10% loss, that’s only 200 USDT lost, which minimally impacts the principal and leaves room for recovery.

**Rule 2: Set maximum loss per trade at 3% of total funds**

For instance, with 2,000 USDT at 10x leverage, set a stop-loss at 1.5%. Once triggered, you lose 300 USDT, hitting exactly the 3% red line of your total capital. Even if you make several wrong calls, you won’t be severely hurt.

**Rule 3: Observe sideways markets, do not add after profits**

Only open positions at key breakout points; avoid trading during consolidation phases, no matter how tempting. Once you open a position, strictly avoid chasing entries to prevent emotional trading.

**The true meaning of full position is to leave room for error**

The original design of the full position mechanism is to buffer against market volatility, but this premise must be based on light position testing and strict risk control.

A trader once shared with me that he kept blowing up his account every month. After applying these three rules for three months, his account grew from 5,000 USDT to 8,000 USDT. He later told me, "I used to think full position was just gambling with my life. Now I finally understand—the real purpose of full position is to survive more steadily."

The survival logic in the crypto world is simple—it's not about who makes the most money fastest, but who can survive the longest. Reduce directional gambling, focus more on position management; slow and steady often turns out to be the fastest way forward.
