编写了一个自用指标公式“双 J 线背离+威廉 ”，旨在寻找长短 J 线（J1短线，J2长线）共振点。共振点：J1、J2几乎同时由下向上反转；J1、J2几乎同时由上向下反转。根据共振点寻求介入时机或回避风险。共振点位置不同，行情上升或下降幅度和强度不同。同时，J1、J2用画线的方式提示出顶底背离，可以更有效地判断行情。
指标同座标给出了长短线威廉指标，有利于综合对行情进行更可靠的判断。
J1、J1、威廉1、威廉2参数，可根据自己经验自行设定。

股票从底部企稳回升，这时绿上，黄红在下潜伏；
真正向上了，就形成绿上，黄中，红下的格局；
等到黄过中线才能确认是真正的涨升，直到红过中线，三线在顶部集合；
下跌时是绿先下，黄，红后下。分别下穿中线，到底部扒伏；
洗盘时，是绿下穿中线，黄，红在上，往往红的不下穿中线，它会浮在中线之上；好像人头在井口观看，而绿线像手在井下提水上来，只要绿线能上勾复起，就是洗盘结束。新一轮升势就会开始。
