主题：[求助]MACD取值问题

 DIFF :=EMA(CLOSE,12) - EMA(CLOSE,26);
DEA  :=EMA(DIFF,9);
MACD :=2*(DIFF-DEA);

dfjc:cross(diff,0);//diff上穿0轴
len1:BARSLAST(dfjc)+1;//dfjc距离现在的位置
cd1:macd>0;
cd2:macd>ref(macd,1);
cd:macd<ref(macd,1) and ref(all(cd2 and cd1,len1),1) and cd1;//判断当前是否是满足F点条件 1.macd红柱 2.macd由长变短 3.diff上穿0轴到上一个K之间满足指定条件

result:VALUEWHEN(cd,HHV(h,len1));
