ret = condition1 and condition2 and condition3 篩選結果卻 正確與錯誤參雜

Hello 
我用了一個指標當作選股參考寫腳本
code 如下 : 

input: FastLength(12), SlowLength(26), MACDLength(9), OscDecrease(5);

variable: price(0);

SetInputName(1, "DIF短天數");

SetInputName(2, "DIF長天數");

SetInputName(3, "MACD天數");

price = WeightedClose();

Value1 = XAverage(price, FastLength) - XAverage(price, SlowLength);

Value2 = XAverage(Value1, MACDLength) ;

Value3 = Value1 - Value2 ;

condition1 = CrossOver(Value1,Value2);

condition2 = Value3[1] < 0 and Value3 > 0;

condition3 = TrueAll(Value3>Value3[1], OscDecrease);

ret = condition1 and condition2 and condition3;

這樣子篩選出來的結果卻是
有 condition1 = 0 and condition2 = 0 and condition3 = 1 的結果 (如附圖)

我期望的結果是 condition1 = 1 and condition2 = 1 and condition3 = 1

想請問這段code是哪邊寫得有問題呢 謝謝
