你这是什么意思？不太懂llv(diff)和ref(llv(diff),1)

判断最近一次绿住macd最小值时，是在绿住上做判断还是在红柱上做判断？

因为最新的macd住红绿不确定，如果是红柱计算红柱值，如果是绿住取绿住值？

mm1:=sumbars(cross(macd,0),1);

nn1:=sumbars(cross(0,macd),1);

 

当前为绿住时的最低diff:

l1:=llv(diff,nn1);

if macd<0 then ll_diff1:=l1;

 

当前为绿住时之前一个绿住最低diff:

l2:=ref(llv(diff,nn1),mm1);

if macd<0 then ll_diff2:=l2;

 

当前为红柱时的最高diff:

h1:=hhv(diff,mm1);

if macd>0 then hh_diff1:=h1;

 

当前为红柱时之前一个红柱的最高diff:

h2:=ref(hhv(diff,mm1),nn1);

if macd>0 then hh_diff2:=h2;
