编写要求：

VAR1:=IF(DATE>=10201201,0,1); VAR2:=EMA(SLOPE(CLOSE,21)*20+CLOSE,55); VAR3:=EMA(CLOSE,3); VAR4:=(2*CLOSE+LOW+HIGH)/4*VAR1; VAR5:=VAR2-VAR3; 风险线:EMA(VAR4,45)*1.15; 必卖线:EMA(VAR4,55)*1.3; 底线:EMA(VAR4,40)*0.85; 铁底线:EMA(VAR4,88)*0.7,COLORRED; 成本线:EMA(VAR4,55),COLORGREEN; 持仓:STICKLINE(VAR5>=0,VAR3,VAR2,0.5,0),LINETHICK2; 减仓:STICKLINE(VAR5

股票网解答：

VAR4:=(2*CLOSE+LOW+HIGH)/4;

底线:=EMA(VAR4,40)*0.85;

铁底线:=EMA(VAR4,88)*0.7;

l<=底线 or l<=铁底线;
