請教：ma1:=ma(c,5);
ma2:=ma(c,10);
ma3:=ma(c,20);
ma4:=ma(c,30);
n:=0;
A:=ref(ma3>ma4,n) and ref(ma2>ma3,n) and ref(ma1>ma2,n);
if ma1<ma2 and ma3>ma4 and ma2>ma3
then repeat n:=n+1 until not(A);
if n>10 then DRAWICON(ma1<ma2,low,4)

目前在練習(xí)用循環(huán)結(jié)構(gòu)~在均線多頭排列超過10天的情況下，在5日均線和10均線死叉的位置提示買入。

公式測試能通過，但一用在副圖就卡死，是不是陷入死循環(huán)了，請問哪里除了問題呢？

n:=0;
A:=ref(ma3>ma4,n) and ref(ma2>ma3,n) and ref(ma1>ma2,n);
if ma1<ma2 and ma3>ma4 and ma2>ma3
then repeat n:=n+1 until not(A);
改成

variable:n=0;
A:=ma3>ma4 and ma2>ma3 and ma1>ma2;
if ma1<ma2 and ma3>ma4 and ma2>ma3  then n:=n+1;

if not(a) then n:=0;

if n>10 then DRAWICON(ma1<ma2,low,4)

n:=0;
A:=ref(ma3>ma4,n) and ref(ma2>ma3,n) and ref(ma1>ma2,n);
if ma1<ma2 and ma3>ma4 and ma2>ma3
then repeat n:=n+1 until not(A);
改成

variable:n=0;
A:=ma3>ma4 and ma2>ma3 and ma1>ma2;
if ma1<ma2 and ma3>ma4 and ma2>ma3  then n:=n+1;

if not(a) then n:=0;

if n>10 then DRAWICON(ma1<ma2,low,4)

貌似沒用，圖上一個箭頭也沒顯示~
