核心逻辑
该指标是一个**资金进出统计指标**，用于分析股票的成交量中有多少是主动买入（买量）和主动卖出（卖量）。 计算原理： - **买量（DT）**：将成交量按一定比例分配给买方。根据当日涨跌情况，如果上涨（收盘≥昨收），则分配更多成交量给买方；反之分配给卖方。 - **卖量（KT）**：剩余的成交量归为卖方。 - **进出量**：买量与卖量的差值，正值表示净流入（资金进入），负值表示净流出（资金退出）。 指标分别统计了**当日、3日、6日、9日**的累计资金进出情况，并换算成占流通市值的百分比。
买卖信号
该指标**不包含明确的买入/卖出信号条件**，主要是资金流向的监控工具。但可参考以下规律： - **资金净流入（进出量>0）**：表示近期资金流入，可能推动股价上涨 - **资金净流出（进出量<0）**：表示近期资金流出，可能导致股价下跌 - 连续多日净流入/净流出可作为趋势判断参考
用法
1. **观察资金流向**：通过"进出量"的正负判断当前资金是流入还是流出 2. **多日累计分析**：结合3日、6日、9日的累计数据，判断中期资金趋势 3. **对比买量卖量**：买量持续大于卖量，说明多方力量较强 4. **结合股价**：若股价上涨伴随资金净流入，可靠性更高；若价涨量缩或价跌量增，需警惕趋势反转 5. **看直方图**：红柱（买量）越多越长越好，黄柱（净流入）表示资金净流入
