核心逻辑
这是一个综合型均线趋势指标，主要通过不同周期的移动平均线组合来判断市场趋势。短期均线（3日均线）上穿中期均线（20日均线）时视为多头信号，同时配合成交量放大、涨幅达到1.8%以上等条件来确认买入时机。卖出信号则结合了价格跌破关键价位、RSI类指标（V4）下穿89以及波动率（V2）等多种判断方法。此外还加入了"肉夹馍"形态识别（类似多方炮组合）和划线辅助功能。
买卖信号
**买入信号：** - DT条件：3日均线向上穿越20日均线，且当日收阳线、收盘价高于昨日、涨幅≥1.8%（显示为"买"） - 肉夹馍形态：连续三天满足特定组合条件（VAR410），显示"肉夹馍"买入信号 **卖出信号：** - V1与V2死叉：（最高价+最低价）/2向下穿越（21日均线+2倍标准差），显示"卖" - V5信号：V4（类似RSI指标）下穿89，显示"卖"
用法
1. **均线多头排列观察**：关注M1上穿M2的位置，结合89日均线（生命线）和321日均线（牛熊线）判断整体趋势方向 2. **买入时机**：当出现"买"字信号或"肉夹馍"信号时，可考虑分批建仓 3. **卖出时机**：当出现"卖"字信号时，应考虑减仓或离场 4. **辅助参考**：保护价和止损价可作为实际操作的参考价位 5. **板块查询**：公式自带概念板块、主题投资和主营业务显示功能，方便把握热点
