通达信无为K线主图指标（趋势型）指标公式

📅 2026-09-10

核心逻辑

这是一个综合型趋势指标，结合了多周期比较逻辑和布林带思路。核心原理是：比较最近4天（含当天）的收盘价，找出最高价和最低价，通过判断当天收盘价与前几天的高低点关系来识别趋势方向。具体包括： - 通过连续4日高低点比较判断多空趋势 - 使用SAR指标判断短期买卖点 - 30日EMA作为生命线基准 - 布林带（中轨26日均线，上下轨2倍标准差）判断波动区间

买卖信号

1. **买入信号（绿色）**：B1是最高价且收盘价是最低价；或收盘价站上SAR（A1） 2. **卖出信号（蓝色）**：B1是最高价且收盘价低于B2；或收盘价跌破SAR（A1） 3. **持股待涨（红色）**：收盘价创新高且上升趋势延续 4. **下跌风险（黄色）**：收盘价创新低且下降趋势延续 5. **变盘信号（品红）**：创新高后遇到最低价支撑，可能反转

用法

1. 红色彩带持股期持有，蓝色彩带抛售期观望 2. 绿色标记处可考虑买入，蓝色标记处考虑卖出 3. 生命线（黄色圆点）向上时看多，向下时看空 4. 股价站上SAR显示为彩龙（黄色），跌破SAR显示为绿色 5. 布林带收窄时关注突破方向，上轨受阻回落可减仓，下轨获得支撑可考虑低吸
