飞狐版本牛股战法
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;
