Position management is not a mathematical formula, but a war against human nature!

The brutality of the contract market never changes a bit because of anyone's prayers. I remember one night when Bitcoin plunged 15% in two hours, and a friend heavily invested in contracts tried to turn the tide by going all-in on N times the contract after being liquidated.
This gambler's mentality is like lighting a torch in a hurricane, destined to turn to ashes in the uncontrollable flames.
Real traders understand to keep each position controlled within 5% of the total capital, guarding their capital like a desert traveler cherishes their water pouch.

There are too many shattered dreams of getting rich quickly wandering in the market. Some mortgage their properties to chase "financial freedom" with a hundred times leverage, while others continue to gamble extravagantly after being liquidated by borrowing from various online loans. Behind these bloody cases lies a disregard for risk management.
The "2% principle" refined over a century on Wall Street is not the timidity of the conservative, but rather the wisdom of survival: a single loss should not exceed 2% of total capital to ensure you can stay at the table forever.

The harsh truth of the contract market: there are no technical indicators that provide timely assistance, no breathtaking reversals that can turn the tide, only cold, hard risk calculation formulas.
Those traders who survive are simply more aware of their own weaknesses than the market—they weave stop-loss orders into a net, build dams with quantitative strategies, and maintain clarity amidst the flood of desire.
Perhaps the true wealth code is hidden between the strokes of the word "restraint".
