高手帮忙编写个出现买入信号的选股公式
原码:RSV=(CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100;
a=SMA(RSV,3,1);
b=SMA(a,3,1);
e=3*a-2*b;
MA$1:MA(CLOSE,n);
IF(a<0) a=0;
IF(a>100) a=100;
IF(b<0) b=0;
IF(b>100) b=100;
IF(e<0) e=0;
IF(e>100) e=100;

IsNowBuy:=FALSE;

sBUY:=CLOSE<1.2*LLV(LOW,7) AND CLOSE>MA(CLOSE,5) AND a>50 AND CROSS(MA(CLOSE,5),MA(CLOSE,10)); //买入信号
DRAWICON (sBUY,LOW,"buy");

//判断现在是否买入状态
IF(sBuy==TRUE OR IsNowBuy[1]==TRUE)
IsNowBuy:=TRUE;
//

 
解答如下:
RSV:=(CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100;
a:=SMA(RSV,3,1);
sBUY:CLOSE<1.2*LLV(LOW,7) AND CLOSE>MA(CLOSE,5) AND a>50 AND CROSS(MA(CLOSE,5),MA(CLOSE,10));
