收到“黄龙天翔81”同学很好的思路如下
 30个交易日内（注：牛市可以缩短日期，熊市增加日期反应更加快）
 三日最高价价平均值=(第一高价+第二高价+第三高价）/3
三日最高价量平均值=（第一高价的量+第二高价的量+第三高价的量）/3
三日最低价价平均值=（第一低价+第二低价+第三低价）/3
三日最低价量平均值=（第一低价的量+第二低价的量+第三低价的量）/3
当三日最高价价平均值/三日最低价价平均值>1.2（注：1.2至1.3之间应该是最好的值，少了坑小，多了庄不给力）
 且三日最高价量平均值/三日最低价量平均值>1.5（注：量能比越大越好，证明缩量得厉害）
 且现价>(三日最高价价平均值+三日最低价价平均值）/2
且现价在10日均线上
 输出预警。
