指标公式逻辑介绍
核心逻辑架构
该指标通过复杂的K线形态组合识别潜在的趋势反转点，主要包含两大判断系统：
K线形态过滤系统（VAR1-VAR5）：
VAR1：双降K线（高/低点均下降）
VAR0：内包K线（高点降低点升）
VAR2：外包K线（高点升低点降）
VAR3：双升K线（高/低点均上升）
VAR5：特殊双底形态（隔日创新低）
时间窗口验证系统（VAR6-VAR60）：
采用6-11日不同周期验证：
要求至少3次双降K线
限制震荡K线数量
最低点位置要求
最高点位置要求
最终需出现双升K线确认
2. 信号触发条件
强势底分型需同时满足：
DFX条件（6-11日形态组合）
AA条件（经典底分型）：
前一日双降
当日双升
收盘突破前高
阳线确认
