将公式中‘红色三角’和‘黄s柱子’分别改为两个预警选股公式
选股公式：
【红色三角】：
趋势线:=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);
买点准备:趋势线<=10;
【黄s柱子】：
A1:=HHV(HIGH,50)/LLV(LOW,100)>1.5;
A2:=(HHV(HIGH,50)-LOW)/(HHV(HIGH,50)-LLV(LOW,100));
A3:=(LOW-LLV(LOW,100))/(HHV(HIGH,50)-LLV(LOW,100));
A4:=HHVBARS(HIGH,50)<LLVBARS(LOW,100);
A5:=A1 AND A2>0.5 AND A3>0.3 AND A4;
A6:=COUNT(A5,20)=1;
抢反弹:A6 AND A5;
