“短”上穿“中”，“ 中”上穿“长”，“长”上穿“超长”预警

编写要求：

P1=8 P2=13 P3=21 P4=34 JJJ:=IF((8)>0.01,0.01*(10)/(8),(3)); DDD:=((5)<0.01 ||(6)<0.01); JJJT:=IF(DDD,1,(JJJ<((5)+0.01) && JJJ>((6)-0.01))); 短:IF(JJJT,0.01*EXPMA(AMOUNT,P1)/EXPMA(VOL,P1),EMA((HIGH+LOW+CLOSE)/3,P1)); 中:IF(JJJT,0.01*EXPMA(AMOUNT,P2)/EXPMA(VOL,P2),EMA((HIGH+LOW+CLOSE)/3,P2)); 长:IF(JJJT,0.01*EXPMA(AMOUNT,P3)/EXPMA(VOL,P3),EMA((HIGH+LOW+CLOSE)/3,P3)); 超长:IF(JJJT,0.01*EXPMA(AMOUNT,P4)/EXPMA(VOL,P4),EMA((HIGH+LOW+CLOSE)/3,P4)); AA:=CROSS(短,中); BB:=CROSS(中,长); CC:=CROSS(长,超长); DRAWICON(AA,O,9); DRAWICON(BB,O,26); DRAWICON(CC,O,24); 分别做三个预警公式， “短”上穿“中” ， “ 中”上穿“长”， “长”上穿“超长”

解答：

?P1=8 ? P2=13 ? P3=21 ? P4=34

JJJ:=IF((8)>0.01,0.01*(10)/(8),(3));
