請問欄位資料長度不夠

請問一下，我想寫一隻均線 20ma < 10ma < 5ma 的選股程式，寫完遇到欄位長度不夠。

看了錯誤商品，有些卻有足夠的長度。以下為程式碼。

input: shortlength(5);  setinputname(1,"短期均線期數");
input: midlength(10);   setinputname(2,"中期均線期數");
input: Longlength(20);  setinputname(3,"長期均線期數");

variable: shortaverage(0);
variable: midaverage(0);
variable: Longaverage(0);

variable: shortaverage1(0);
variable: midaverage1(0);
variable: Longaverage1(0);

shortaverage = average(close,shortlength);
midaverage = average(close,midlength);
Longaverage = average(close,Longlength);

shortaverage1 = average(close[1],shortlength);
midaverage1 = average(close[1],midlength);
Longaverage1 = average(close[1],Longlength);

condition1 = shortaverage > midaverage;
condition2 = midaverage > Longaverage;
condition3 = shortaverage1 < shortaverage;
condition4 = midaverage1 < midaverage;
condition5 = Longaverage1 < Longaverage;

if condition1 and condition2 and condition3 and condition4 and condition5 then ret = 1;
