核心逻辑
该指标是一个复合型趋势跟踪系统，主要包含三个核心部分： 1. **主趋势线**：通过三次SMA嵌套平滑处理价格（类似"蛇形"均线），用于追踪中期趋势 2. **止损线**：动态计算的支撑位，当价格跌破时可能触发止损 3. **K线形态识别**：识别连续上涨（红三兵到七连阳）和连续下跌（黑三兵到七连阴）的K线组合，用于判断趋势转折 4. **波动率分析**：结合均线偏离度和布林带原理判断超买超卖 整体逻辑是：通过平滑后的均线判断趋势方向，结合K线形态和波动率指标寻找趋势转折点，并设置动态止损保护。
买卖信号
**买入信号：** - A32条件触发（符合特定买入形态）时显示"←═≒∝"黄色文字信号 - LIFENGCYC条件满足（前日偏离度<-15%且当日回升）时显示紫色"☆"信号 - VAR1B条件满足（连续下跌后出现上涨K线）时显示青色柱状线 **卖出信号：** - AA条件满足（连续上涨后出现下跌K线）时显示绿色柱状线 - B2<SMA2时显示绿色线条（趋势转弱） - 停损下限被跌破时触发止损
用法
1. **趋势判断**：红线表示上升趋势（买入持有），绿线表示下降趋势（观望或卖出） 2. **买入时机**：关注"☆"和"←═≒∝"信号出现时，结合红线和蓝色区域判断 3. **止损保护**：关注停损下限线，跌破后及时止损 4. **形态配合**：红三兵/七连阳后出现绿色柱状线可能预示顶部；黑三兵后出现青色柱状线可能预示底部 5. **综合分析**：建议结合成交量和其他趋势指标综合判断，避免单一信号交易
