Candlestick Basics | K线基础

Candlestick charts from 18th century Japan remain the most powerful technical analysis tool. Each candle shows open, high, low, and close. The body represents opening-to-closing range; wicks show high-low range. Green candles indicate price increase, red candles decrease. K线图起源于18世纪的日本，是技术分析最强大的工具。每根K线显示开盘价、最高价、最低价和收盘价。

Single Candle Patterns | 单K线形态

Doji (open equals close, indicating indecision), Hammer (small body with long lower wick, reversal signal), Shooting Star (small body with long upper wick, bearish), and Marubozu (no wicks, strong momentum). Each reveals unique market sentiment. Doji（开盘等于收盘，表示犹豫不决）、Hammer（长下影线小实体，反转信号）。

Reversal Patterns | 反转形态

Head and Shoulders: three peaks with higher middle peak, break below neckline confirms reversal. Double Top: price tests resistance twice and reverses. Inverse Head and Shoulders signals bullish reversal. These patterns help identify trend changes before they happen. 头肩顶：三个峰中间最高，跌破颈线确认反转。双顶：价格两次测试阻力后反转。

Continuation Patterns | 持续形态

Flags form as rectangular consolidations sloping against the prior trend. Pennants are small symmetrical triangles after strong moves. Wedges can signal continuation or reversal depending on slope. These patterns help traders anticipate trend resumption. 旗形表现为与前期趋势相反的矩形整理。三角旗是强劲波动后的小对称三角形。

Volume Confirmation | 成交量确认

Volume confirms price action validity. Increasing volume during breakouts validates the move. Volume Profile shows trading activity at specific price levels. On-Balance Volume (OBV) tracks cumulative flow. Divergence between price and volume signals potential reversals. 成交量确认价格行为的有效性。突破期间成交量增加验证了走势。
