核心逻辑
这是一个综合型趋势交易指标，结合了均线系统、布林带和超买超卖指标。核心逻辑是以21日均线（界）作为多空分界线，配合13日均线（风险线）和27日均线（止损线）形成风险控制体系，同时使用VAR1/VAR2/VAR3超买超卖指标判断市场情绪。当价格站上21日均线且处于上升趋势时显示红色K线，表示多头行情；反之显示黄色K线，表示调整或下跌趋势。
买卖信号
1. **买入信号（Ｂ）**：VAR2上穿MA(VAR3,6)，表示超卖区金叉，形成买入机会 2. **卖出信号（Ｓ）**：MA(VAR3,6)下穿VAR1，表示超买区死叉，形成卖出机会 3. **底背离信号**：MA5上穿21日均线（界），且价格处于低位，可能出现底背离 4. **主升浪信号**：价格上穿27日均线（止损线）且27日均线大于13日均线（风险线），表示进入主升浪行情
用法
1. **趋势判断**：价格站上21日均线（界）且21日均线向上倾斜时，表示处于多头趋势，可考虑做多；反之则观望 2. **买入时机**：当出现"Ｂ"字信号且价格站上21日均线时，是较佳买入点 3. **卖出时机**：当出现"Ｓ"字信号或价格跌破27日均线时，应考虑止盈或止损 4. **风险控制**：13日均线作为风险线，跌破应严格止损；27日均线作为止损线参考 5. **主升浪确认**：当出现"主升浪"提示时，往往是一波较大行情的起点，可积极持仓
