主题：表达不一致

我又看了下。调整下代码顺序。

再简化下代码：

INPUT:N(30,1,250,10);
MA30:MA(CLOSE,N);
A:CLOSE-AVGENTERPRICE;
B:CLOSE-MA30;
D:AVGENTERPRICE-CLOSE;
E:MA30-CLOSE;

IF ((D>0 AND D>=3*E) or D<0) AND CROSS(CLOSE,MA30) THEN
BEGIN
SELLSHORT(holding<0,HOLDING ,MARKET);
BUY(holding=0,20%,MARKET);
END


IF ((A>0 AND A>=3*B) or A<0)  AND CROSS(MA30,CLOSE) THEN
BEGIN
SELL(holding>0,HOLDING,MARKET);
BUYSHORT(holding=0,20%,MARKET);
END
