1分鐘頻率獲取日線平均移動成本

我用1分鐘頻率去抓取 日線的close然後算出均線 但是60ma這邊一直顯示"資料長度不足"不知道錯在哪邊

我拿掉superLongAvaerage的話前面兩個可以跑 

variable: shortaverage(0);

variable: Longaverage(0);

variable: SuperLongaverage(0);

shortaverage=Average(getfield("Close","D"),5);

Longaverage = Average(getfield("Close","D"),20);

SuperLongaverage = Average(getfield("Close","D"),60);

settotalbar(63);

print(shortaverage);

print(Longaverage);

print(SuperLongaverage);
