将“扭亏为盈”公式中出现上箭头信号改为选股公式

编写要求：

请将公式中出现上箭头信号改为选股公式，选出当天出现上箭头的个股 BIAS1:=MA((CLOSE-MA(CLOSE,13))/MA(CLOSE,13),3)*100,COLORWHITE; BIAS3:=MA((CLOSE-MA(CLOSE,27))/MA(CLOSE,27),3)*100,COLORFF00FF,LINETHICK2; 操作区:IF(BIAS3<0,BIAS3,0),COLORRED,LINETHICK2; 观望区:IF(BIAS3>0,BIAS3,0),COLORGREEN,LINETHICK2; VAR1:=IF(DATE>=1990601,0,1); VAR2:=TROUGHBARS(3,15,1)<10; VAR3:=PEAKBARS(3,15,1)<10; VAR4:=IF(VAR2=1,50,0); VAR5:=IF(VAR3=1,50,0); TJ1:=观望区REF(操作区,1); 顶: IF(TJ1 AND VAR5=50,15,0),STICK,LINETHICK1,COLORGREEN; 底: IF(TJ2 AND VAR4=50,10,0),STICK,LINETHICK1,COLORRED; DRAWICON(TJ1 AND VAR5=50,-2,2); DRAWICON(TJ2 AND VAR4=50,11,1);

解答：

?BIAS1:=MA((CLOSE-MA(CLOSE,13))/MA(CLOSE,13),3)*100,COLORWHITE;

?BIAS3:=MA((CLOSE-MA(CLOSE,27))/MA(CLOSE,27),3)*100,COLORFF00FF,LINETHICK2;
