请老师出手把（工作线）指标改写选股公式，出现笑脸时写一个选股指标，上涨图给老师参考。 A1:=EMA(C,14)COLORWHITE,LINETHICK4; A1X:=(A1-REF(A1,1))/REF(A1,1)*100,NODRAW; 出击:IF(A1X>=0,REF(EMA(C,14),BARSLAST(CROSS(A1X,0))+1),DRAWNULL)COLORRED,LINETHICK4; 休假:IF(A1X<0,REF(EMA(C,14),BARSLAST(CROSS(0,A1X))+1),DRAWNULL)COLORGREEN,LINETHICK4; STICKLINE(CROSS(A1X,0),C,O,2,0)COLORYELLOW; STICKLINE(CROSS(0,A1X),C,O,5,0)COLOR666666; STICKLINE(CROSS(A1X,0)OR CROSS(0,A1X),REF(EMA(C,14),1),REF(EMA(C,14),1)*0.998,2,0)COLORWHITE,LINETHICK4; STICKLINE(ISLASTBAR,REF(EMA(C,14),1),REF(EMA(C,14),1)*0.998,5,0)COLORWHITE,LINETHICK4; 工作线:=EMA(C,14); 止盈线:EMA(C,7),LINETHICK1,COLORGRAY; 工作区:IF(C>=工作线 AND EMA(C,14)>=EMA(C,25),工作线,DRAWNULL), COLORRED,LINETHICK4; 准备区:IF(C>=工作线 AND EMA(C,14)EMA(C,14),L*0.99,1); DRAWICON(COUNT(CEMA(C,14) AND COUNT(C>止盈线,11)>=3,H*1.03,2); DRAWICON(CROSS(工作线,C) AND EMA(C,14)>EMA(C,25),H*1.01,10);{止损位} IF(CROSS(生命线,工作线),HIGH*1.04,DRAWNULL),CIRCLEDOT,COLORGREEN;
