I received a trader's request for help early in the morning: 10,000U full position with 20x leverage going long, and it was liquidated after just a 5% adverse move.

This case reveals a common misconception—many people equate "full position" with "risk tolerance," but in fact, it's the opposite. Full position is actually an accelerator for liquidation. Using 900U with 10x leverage, a 5% adverse move results in liquidation; similarly, with 10x leverage and a 100U position, it takes a 50% move to be liquidated. The key difference isn't the leverage multiple but the weight of the position.

A trader who has been zero-liquidation for half a year and still doubled their account summarized three ironclad risk control rules:

**Rule 1: Do not invest more than 20% of total funds in a single trade**
Protecting the principal means protecting the chance to turn things around. Even with small positions, continuous losses still leave enough buffer in the account.

**Rule 2: Limit single-loss to within 3% of total position**
No trading strategy is 100% accurate. Set strict stop-loss levels to ensure that even with consecutive mistakes, the account can withstand the losses.

**Rule 3: Do not open positions in choppy markets; do not chase profits during upward moves; only enter during trend breakouts**
Most liquidations happen during frequent operations in sideways markets. Wait for clear trend signals—once they appear, that's the real opportunity.

Full position is essentially a buffer, not gambling. Spend less time guessing the market direction, and focus more on position control—this way, you can be more stable and go further.
