通达信DDX和谐指标（资金型）指标公式

买卖信号

1. **出击买入信号**：主力线上穿-10、-2、0或前一日主力线上穿0，同时满足：趋势>=REF(趋势,1)且趋势<80、散户>-35、主力>REF(主力,1)、DIF>DEA、收盘价3日内涨幅<10% 2. **预警买入信号**：DDX>0且5日均量线上穿5日均量的均量，同时DDX1上穿DDX2 3. **★符号预警**：当预警条件满足时在DDX上方显示★符号

用法

1. **适用场景**：适用于判断主力资金动向，寻找资金流入的买入机会 2. **核心逻辑**：DDX表示主力资金净流入流出情况，正值表示主力买入为主，负值表示卖出为主 3. **出击条件**：需同时满足主力资金转强、趋势向上、散户离场、MACD金叉等多个条件共振，出击信号较为严格 4. **预警条件**：资金持续流入且成交量放大时触发预警 5. **注意事项**：该指标结合了资金面、技术面多重因素，信号较为可靠，但需结合大盘环境和个股基本面综合判断
