自動交易回測失敗

回測期貨自動交易策略卻一直顯示空白,是否腳本撰寫有問題呢?

腳本如下:

input: Price(close); setinputname(1,"價格");

input: Length1(10); setinputname(2,"長期");

input: Length2(5); setinputname(3,"短期");

settotalbar(3);

var:InCondition(false),OutCondition(false);

InCondition  = Price > highest(high[1] ,Length1) 

OutCondition = Price < lowest(low[1] ,Length2) 

if position = 0 and InCondition then setposition(1,market);

if position <> 0 and OutCondition then setposition(0,market);

請小編幫忙 謝謝
