买卖信号
1. **中线【买入】**：COUNT(CLOSE<EMA18,5)=4 AND CLOSE/EMA18>1.004 AND CROSS(CLOSE,EMA18) AND EMA18>=REF(EMA18,1) - 条件：连续5天内有4天收盘价低于EMA18，且收盘价上穿EMA18，同时EMA18向上运行 2. **洗盘结束**：VAR111<=VAR110 AND VAR18>REF(VAR18,1)，经FILTER过滤20天 - 条件：VAR111小于等于VAR110，且VAR18较前一天增加 3. **抄底**：CROSS(VAR23,VAR24) AND VAR23<20，经FILTER过滤10天 - 条件：VAR23上穿VAR24，且VAR23低于20 4. **逃顶**：CROSS(VAR24,VAR23) AND VAR23>80，经FILTER过滤5天 - 条件：VAR24上穿VAR23，且VAR23高于80
用法
1. **均线系统**：使用6、18、55、144、250、288日等多周期均线判断趋势 2. **中线买入信号**：在下跌趋势中，连续4天收盘价低于18日均线后，出现放量上穿18日均线时买入，属于趋势反转信号 3. **洗盘结束信号**：结合VAR14和VAR18判断主力洗盘是否结束，可在洗盘结束时买入 4. **抄底信号**：VAR23<20表示超卖，结合金叉可尝试抄底 5. **逃顶信号**：VAR23>80表示超买，结合死叉可考虑逃顶 6. **注意事项**：该指标综合了均线、威廉变异离散量（VAR12/VAR14/VAR18）和KDJ类指标（VAR22/VAR23/VAR24），信号较多需综合判断，建议结合成交量和其他指标验证
