Understanding S&R | 理解支撑阻力

Support is a price level where buying pressure exceeds selling, preventing further decline. Resistance is where selling pressure exceeds buying, preventing further advance. These levels form due to trader memory, pending orders, and institutional interest zones. 支撑位是买压超过卖压阻止进一步下跌的价格水平。阻力位是卖压超过买压阻止进一步上涨的水平。

Drawing Levels | 绘制关键位

Horizontal S&R levels connect significant highs and lows. Trendlines connect ascending/descending swing points. Moving averages (50, 100, 200) act as dynamic S&R. Fibonacci retracement identifies potential reversal zones within trends. Volume Profile VAH/VAL show high-volume nodes. 水平支撑阻力连接重要高点和低点。趋势线连接上升/下降摆动点。斐波那契回撤确定趋势中的潜在反转区域。

Role Reversal | 角色转换

When price breaks resistance, it often becomes support (breakout confirmation). When price breaks support, it often becomes resistance on retest. This principle is fundamental to breakout trading. Failed breaks (false breakouts) are powerful reversal signals. 当价格突破阻力时，它往往成为支撑（突破确认）。这是突破交易的基本原则。虚假突破是强反转信号。

Breakout Trading | 突破交易

Bullish breakout: price exceeds resistance with increased volume. Bearish breakout: price falls below support. Entry after confirmed close beyond level. Stop-loss inside the broken zone. Target measured move (project height of the pattern). Volume confirmation is critical for avoiding false breakouts. 看涨突破：价格以放量突破阻力。目标为测量移动（形态高度投射）。成交量确认对避免虚假突破至关重要。

Mean Reversion at Levels | 关键位均值回归

When price reaches strong S&R with overextended RSI (above 70 or below 30), mean reversion opportunities arise. Entry at the level with stop beyond it. Target mid-range. This strategy works best in ranging markets and at major round-number levels. 当价格到达强支撑阻力位且RSI过度延伸时，均值回归机会出现。该策略在震荡市场和整数关口最有效。
