請問最后一行代碼有無出錯?
variable:bj=0;
tr1 : max(max((high-low),abs(ref(close,1)-high)),abs(ref(close,1)-low));
atr : ma(tr1,20); //atr公式
ma20:ma(close,20); //20日均線
a1:=0.01*valuewhen(barpos=1,asset); //初始資金的1%
a2:=floor(a1/(2*atr)); //開倉手數
a3:=ref(hhv(high,20),1); //20日高點
if holding=0 and close>a3 and close>ma20 and bj=0
then begin
buy(1,a2,marketr);
bj:=1;
end //第一次開倉
if holidng=0 and close>enterprice+2*atr and bj=1
then begin
buy(1,a2,marketr);
end //請問這里還是if holidng=0嗎?還是應該是if holidng>0 ?
加倉的話要大于0,
等于0是在空倉的情況下用,
