Many people blame their margin calls entirely on leverage multiples, but the real issue lies in the position size—failing to leave room for mistakes.

For a $1000 account, how big is the difference?
• Using 900U with 10x leverage, a 5% adverse move could wipe out the account.
• Using 100U with 10x leverage, you'd need a 50% drop to threaten your funds.

The latter approach is a completely different game. I’ve maintained a full position for half a year—not only surviving but doubling my capital. The secret boils down to three unbreakable rules:

**Rule 1: Never open a single position exceeding 20% of the account**
For a $10,000 account, only use $2,000 per trade. Even if this trade hits the stop-loss and exits, it only risks 2-4% of the total capital, which is manageable. You can continue trading next time.

**Rule 2: Limit single trade losses to within 3% of total funds**
Set your stop-loss before opening the position. For example, with a $2,000 position, set a 1.5% stop-loss, capping the maximum loss at $300—this is the bottom line, and it must not be loosened.

**Rule 3: Only act in clear trends, take profits and exit**
• Abandon sideways markets; wait for a trend breakout before entering.
• Don’t be greedy after making money—thinking "it might still go up" is the most dangerous mindset. Use trailing stops to protect profits and avoid emotional trading.

The correct way to operate in full position mode isn’t to throw all chips at once and gamble, but to leverage flexibility by setting risk limits on each trade. A friend used to blow up his account every month, but after adopting these rules, he turned $2,600 into $53,000 in three months.

Living longer in this market is more valuable than making quick profits. True stability isn’t about avoiding risk altogether but about locking in risk with strict rules.
