红绿灯（源码 副图/选股、通达信）
红绿灯副图的选股思路；本人做了一下研究，经过对副图的解读后编了一个选股指标，思路是：1 将红、黄灯后一交易日出现绿灯提示后提炼出来，2 整合四个参数下的红、黄灯变绿灯后作为选股提示条件；3 经过测试后发现，全部符合条件后会以后掉不少走势不错的个股，所以就将最后的选股条件设定为大于等于三个参数，并添加了阳线实体大于上影线部分的限制条件，其目的就是要金莲选出上影线很小或光头阳的个股，这样就过滤掉了不少杂波，本想在附加几个限制条件，但考虑到每个人的反洗研判角度不同，就放弃了。洗完喜欢的坛友自己根据你的喜好来更改，如果你不会那就仅供参考，千万不要盲目的依照指标胡乱操作，有的人就是拿到指标买个股票涨了就开心跌了就埋怨指标不好，说发指标的大骗子，指标只是每个人用来减轻你的选股劳动强度的工具而已。可以作为预警选股使用
