通达信「高抛低吸」副图+选股公式全解析：捕捉红柱全仓、棕柱低吸的波段神器
公式介绍
该指标基于EMA均线差与5日随机指标构建动量柱，通过红、蓝、棕、白四色柱体判断买卖点。红柱代表多头加速（全仓信号），棕柱提示超卖低吸，蓝柱为离场警示，白柱则风险显现。副图还叠加了彩色带状线（gspt1与gspt2），直观反映趋势强弱。
使用方法
1. 副图：红柱放大且出现向上箭头（图标11）时全仓；棕柱（gspt7<-0.5）出现时低吸；蓝柱（gspt3<0且下降）离场；白柱（gspt3>0但下降）减仓。
2. 选股：公式`XG`筛选出满足“gspt16低吸信号+gspt3向上且为正”的个股，适合盘后选股。
3. 注意：结合成交量与均线过滤，避免单边下跌中过早抄底。
