红极云梯——趋势确认+红柱买入信号，三轨定位支撑压力

这个指标做三件事：用13日EMA方向判断趋势、用四日K线重叠找支撑位、用120日高低算出三轨定位压力支撑。三件事同时满足时，出红色箭头信号——这就是"云梯启动"。

主图红色K线=趋势向上持股，灰色K线=趋势向下观望。副图红柱/橙柱配合箭头信号，一目了然。

信号逻辑拆解

条件①：13日EMA方向向上

EMA13今日值>昨日值，说明中期趋势向上。这是最基础的过滤——只做多头方向的票。

条件②：四日K线重叠支撑确认

最近4根K线的高开低收互相包含（交叉重叠），说明多空在这个价位反复争夺，形成密集成交区。当价格突破这个区域时，支撑力度很强。

条件③：三轨系统定位

120日高低价计算出上轨（1.2倍中轨）、中轨、下轨（0.8倍中轨）。价格在中轨以上=强势区，在下方=弱势区。

选股额外过滤：

收盘价≥中轨（站上关键位）、量>5日均量（放量确认）、收阳线、低点不低于中轨97%（不远离支撑位）、排除ST/北交所/科创板/退市风险股。

使用说明

主图用法：红色K线持股，灰色K线观望。三轨系统中，价格站上中轨（紫线）为强势区，跌破中轨注意风险。红色箭头=首次趋势确认信号。

副图用法：红柱=趋势向上，橙柱渐变=趋势向下。箭头出现=趋势首次转多。白线为下轨参考。

选股时机：收盘后运行选股，"云梯启动"信号已包含7层过滤（趋势+支撑+放量+站上中轨+收阳+排除ST/北交所/科创板），选出后次日观察竞价。

止损纪律：主图变灰K线就是离场信号，不用等亏损扩大。中轨跌破也应减仓。

适用周期：日线最佳。60分钟级别也可以用，但信号会更频繁，需要配合止损更紧凑。
