公式编写要求：
指标如下：Q2:=(CLOSE-LLV(LOW, 18))/(HHV(HIGH, 18)-LLV(LOW, 18))*100; Q3:=SMA(Q2, 9, 1); Q4:=SMA(Q3, 3, 1); 长趋势:3*Q3-2*Q4,COLORWHITE,LINETHICK3; 趋势线:EMA(Q3, 3),COLORRED,LINETHICK3; DRAWTEXT(CROSS(趋势线, 长趋势) AND REF(长趋势,1)>80, REF(长趋势,3), '◤顶'),COLOR00FF00,LINETHICK1;逢低买: DRAWTEXT(REF(CROSS(趋势线,长趋势),82) AND 趋势线>1.3*长趋势,长趋势,'逢低买'),LINETHICK1;买: DRAWTEXT(REF(CROSS(长趋势,趋势线),1) AND 长趋势>1.3*趋势线,趋势线,'★买入'),COLORYELLOW,LINETHICK1; 金叉: CROSS(长趋势,趋势线);DRAWTEXT(金叉,趋势线,'金叉'),COLORYELLOW;请老师在”金叉“和”逢低买“各做一个选股公式
公式编写方法：
Q2:=(CLOSE-LLV(LOW, 18))/(HHV(HIGH, 18)-LLV(LOW, 18))*100;
Q3:=SMA(Q2, 9, 1);
Q4:=SMA(Q3, 3, 1);
长趋势:=3*Q3-2*Q4;
趋势线:=EMA(Q3, 3);
金叉: CROSS(长趋势,趋势线);
==========================
{逢低买}
Q2:=(CLOSE-LLV(LOW, 18))/(HHV(HIGH, 18)-LLV(LOW, 18))*100;
Q3:=SMA(Q2, 9, 1);
Q4:=SMA(Q3, 3, 1);
长趋势:=3*Q3-2*Q4;
趋势线:=EMA(Q3, 3);
逢低买:REF(CROSS(趋势线,长趋势),82) AND 趋势线>1.3*长趋势;
