先建一个公式“ZMACD”：
 {ZMACD}
 DIFF : EMA(CLOSE,25) - EMA(CLOSE,65);
 DEA  : EMA(DIFF,45);
 

上面公式要单独建，建好后，再建一个公式“牛股战法”：
 
{牛股战法}
 DIFF := EMA(CLOSE,12) - EMA(CLOSE,26);
 DEA  := EMA(DIFF,9);
 牛股攻击 : 2*(DIFF-DEA), COLORSTICK;
 stickline(牛股攻击>ref(牛股攻击,1) and diff>dea,牛股攻击,0,10,0),COLORRED;
 stickline(牛股攻击>ref(牛股攻击,1) and diff>dea,牛股攻击,0,1,0),coloryellow;
 A:"zMACD.DIFF#WEEK",LINETHICK2;
 B:"zMACD.DEA#WEEK",LINETHICK2;
 PARTLINE(a<ref(a,5),a),linethick2,colorblue;
