通达信双量成交量指标（成交量型）指标公式

核心逻辑

该指标是一个成交量分析工具，主要用于判断成交量的主动性。核心原理是通过比较收盘价与开盘价的关系，结合价格波动幅度，计算出主动买入量和主动卖出量。公式首先计算VAR1（成交量与价格波动的关系值），然后根据当日涨跌情况分别计算主动买入（红柱）和主动卖出（粉红柱）的成交量大小。同时包含预成交量估算和换手率统计，用于分析资金流向和市场活跃程度。

买卖信号

1. **买入信号**：当"买"值大于0时，显示红色柱子，表示存在主动买入量 2. **强势信号**：当成交量大于5日均量，且股价上涨时，显示红色柱状线（变） 3. **买卖比例**：通过"买卖%"指标观察主动买入与主动卖出的比值 4. **换手率观察**：换手率明显增加时可能表示资金活跃

用法

1. 观察红色柱子（买）的增长情况，若持续放大且股价上涨，表明买盘强劲 2. 对比买与卖的柱状高度，买大于卖时表示多方占优 3. 配合"变"信号（成交量放大且股价上涨）判断短期强势 4. 换手率突然放大时需关注是否伴随股价异动 5. 可结合股价趋势判断资金是持续流入还是流出
