A fan reached out to me early in the morning to complain: With the same market conditions, why did you earn 42% while I lost 28%?

Actually, we are looking at the same candlestick chart, but the difference lies in completely different trading logic. He sticks to the principal, while I use a profit rolling method.

This approach didn't come out of nowhere. After three margin calls over 8 years and losing 200,000 yuan, I gradually developed a relatively stable profit framework. The core idea is simple: preserve the principal and use profits to fight.

How exactly does it work? The first step is to respect the principal. Use 5% as the trial order size, with a strict stop loss set at 0.8%. If there are no clear signals, stay out of the market. This ensures your principal beats over 80% of traders.

Once profits reach 50%, split into two parts—half to lock in profits and secure gains, and the other half as operating capital for further entries. Only use profits to add positions, while the principal remains untouched.

After floating profits exceed the principal, switch your mindset. Take out 10% of the profits for hedging insurance, and extend the stop loss to 50%. This way, even if there's a pullback, you can withstand it, and profits will continue to appreciate.

The real turning point is within 3 minutes—breakout combined with volume expansion goes all in; if it breaks support with decreasing volume, close all positions immediately—no room for hesitation.

When the drawdown reaches 15%, lock in half of the profits immediately, and let the remaining part continue to run. Before each trading day's close, withdraw all profits earned that day, leaving only the principal plus 10% of liquid funds in the account. This helps avoid impulsive heavy positions.

Market opportunities are always present, but most people lack discipline. Use profits to take risks, let the principal sleep, and finally, watch the market close with a smile.
