在公式中出现蓝色箭头的时候做一条选股公式

 网友求助：

请老师在公式中出现蓝色箭头的时候做一条选股公式如图

卖出线: 99;
阶段卖: 90;
趋势: 3*SMA((CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27))*100,5,1)-2*SMA(SMA((CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27))*100,5,1),3,1);
底部: 10;
买入警戒: IF(趋势<=10,50,0)LINETHICK2 COLORGREEN;
买入信号: IF(CROSS(趋势,底部),100,0);
卖出警戒: IF(趋势>=90,50,100)LINETHICK2 COLORRED;
BIAS1:=(C-MA(C,6))/MA(C,6)*100;
BIAS2:=(C-MA(C,12))/MA(C,12)*100;
BIAS3:=(C-MA(C,24))/MA(C,24)*100;
BIAS:=(BIAS1+2*BIAS2+3*BIAS3)/6;
乖离:=MA(BIAS,3);
极品底:(CROSS(BIAS,乖离) AND 乖离<-9),COLORRED;
STICKLINE(CROSS(BIAS,乖离) AND 乖离<-9,10,0,5,0),COLORRED;
底:IF((MA(C,5)-C)/C>0.03 AND (MA(C,10)-MA(C,5))/MA(C,5)>0.03,23,0),LINETHICK2,COLORFF00FF;

解答如下：

趋势:=3*SMA((CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27))*100,5,1)-2*SMA(SMA((CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27))*100,5,1),3,1);
底部:=10;
买入信号:CROSS(趋势,底部);
