Technical Analysis（技术分析）
A family of methods using market data to form conditional signals—not a reliable forecast of future price direction.
Technical analysis studies price, volume, volatility, positioning, and related market data to identify patterns or construct trading rules. Signals depend on definitions, parameters, timeframe, data quality, execution, and market regime, and historical patterns do not guarantee future results.
Frequently Asked Questions
Does technical analysis predict future prices?
No method reliably predicts future prices in all markets or periods. Indicators provide conditional signals that can fail, reverse, or become crowded.
Are indicators independent evidence?
Often not. Many indicators are transformations of the same price and volume data, so combining several can create an illusion of confirmation without independent information.
What makes a backtest misleading?
Overfitting, look-ahead bias, survivorship bias, data revisions, parameter searching, omitted costs, unrealistic fills, and regime selection can materially overstate results.
Can technical analysis be used without risk controls?
No strategy removes loss risk. Position sizing, liquidity, gap risk, fees, market impact, stop execution, and portfolio-level exposure remain important.
