出现买入的选股公式

 网友求助：

VAR1:=(CLOSE-LLV(LOW,20))/(HHV(HIGH,20)-LLV(LOW,20))*100;
VAR2:=SMA(VAR1,20,1);
VAR3:=SMA(VAR2,15,1);
VAR4:=(3*VAR2+2*VAR3)/4;
VAR5:=REF(VAR4,1);
RSA:(SMA(MAX(VAR4-VAR5,0),2,1))/(SMA(ABS(VAR4-VAR5),2,1))*100;
RSB:MA(RSA,10);
买入:IF(RSB<10 AND CROSS(RSA,RSB),50,0),STICK,LINETHICK3,colorFF;
卖出:IF(RSB>90 AND CROSS(RSB,RSA),50,0),STICK,LINETHICK3,colorFF00;
DRAWTEXT(RSB<10 AND CROSS(RSA,RSB),40,'买入'),colorFF;
DRAWTEXT(RSB>90 AND CROSS(RSB,RSA),40,'卖出'),colorFF00;

RT 谢谢了~~~~~~~~

解答如下：

VAR1:=(CLOSE-LLV(LOW,20))/(HHV(HIGH,20)-LLV(LOW,20))*100;
VAR2:=SMA(VAR1,20,1);
VAR3:=SMA(VAR2,15,1);
VAR4:=(3*VAR2+2*VAR3)/4;
VAR5:=REF(VAR4,1);
RSA:=(SMA(MAX(VAR4-VAR5,0),2,1))/(SMA(ABS(VAR4-VAR5),2,1))*100;
RSB:=MA(RSA,10);
RSB<10 AND CROSS(RSA,RSB);
