主题：为什么我写的程序测试不出来？

INPUT:N1(9,1,100,10)，M1（3，2，100，1），M2(3,2,30,3),M3(120,1,250,1);

RSV:= (CLOSE-LLV(LOW,N1))/(HHV(HIGH,N1)-LLV(LOW,N1))*100;

K:=SMA(RSV,M1,1);

D:=SMA(K,M2,1);

B:=MA(CLOSE,M3),COLORRED;

BUY(CROSS(K,D) AND CLOSE>B AND TIME>=090500 AND TIME<=145500 AND TIME>=210500 AND TIME>=210500 AND TIME<=225500 AND HOLDING=0,20%,MARKET);

SELL(CROSS(D,K) AND TIME>=145500 AND TIME>=225500 AND HOLDING>0,HOLDING,MARKET);

BUYSHORT(CROSS(D,K) AND CLOSE<B AND HOLDING=0 AND TIME>=090500 AND TIME<=145500 AND TIME>=210500 AND TIME>=210500 AND TIME<=225500,20%,MARKET);

SELLSHORT(CROSS(K,D) AND TIME>=145500 AND TIME>=225500 AND HOLDING<0,HOLDING,MARKET);

这段代码问题出在哪里？
