通达信BOLL+变色均线+SAR组合主图指标（趋势型）指标公式

买卖信号

1. **短买信号**：VAR19条件满足时，在最低价位置显示"短买"文字提示（绿色） - 条件：前一日持币（VARD-VAR18），今日转为持股（VAR1） 2. **离场信号**：VAR1A条件满足时，在最高价+0.1位置显示"离场"文字提示（粉色） - 条件：前一日持股（VAR1-VARC），今日转为持币（VARD） 3. **持股区间**：当VAR1-VARC任一条件满足时，显示红色粗点状线（辰星线） 4. **持币区间**：当VARD-VAR18任一条件满足时，显示浅灰色粗点状线（辰星线） 5. **急速超跌**：(C-MA(C,34))/MA(C,34)*100<-14

用法

1. **适用场景**：中短期趋势交易，适合震荡市和趋势行情 2. **核心逻辑**： - 辰星线（黄线）为短期均价，牵牛线（绿线）为26日均线 - 当MA3≤辰星线时，显示绿色等待线（牵牛线） - 利用布林带思想设置上轨、下轨、上极限、下极限 3. **交易策略**： - "短买"信号：持币转持股时买入 - "离场"信号：持股转持币时卖出 - 红色点状线区域为持股期，灰色点状线区域为持币期 4. **注意事项**： - 该指标包含"持股"和"持币"状态判断，属于趋势跟踪系统 - 急速超跌可用于抢反弹参考 - 建议结合其他指标或均线系统确认信号
