Evaluate macroeconomic factors (GDP/CPI), policy trends, and corporate financial reports to determine the intrinsic value of assets, suitable for medium to long-term investment decisions. Combine changes in trading volume/open interest to verify the reliability of price trends, for example, a significant breakout above key resistance levels is more effective. Strictly set stop-loss levels (usually 3%-5% of principal), control individual position sizes, avoid emotional trading, optimize strategies through risk-reward ratios, cross-reference different time frames (daily/weekly) and analysis methods (technical + fundamental) to improve decision-making success rates. Beginners are advised to practice on a simulated account and establish a trading system before operating in real markets.
