编写要求：

20,POINTDOT;80,POINTDOT;VAR1:=(2*C+H+L)/4;VAR2:=LLV(LOW,34);VAR3:=HHV(HIGH,34);AA:EMA((VAR1-VAR2)/(VAR3-VAR2)*100,5),COLORRED;BB:EMA(AA,5)COLOR00FFFF;DRAWBAND(AA,RGB(200,0,0),BB,RGB(0,200,200));DRAWICON(CROSS(AA,BB),BB-5,1);DRAWICON(CROSS(BB,AA),AA+5,2);STICKLINE(AA<20,2,7,1,1),COLORFF00FF;STICKLINE(AA>80,92,97,1,1),COLOR00FFFF;IF(AA>=BB,100,108);IF(AA=BB,105,1);DRAWICON(BB>AA,-8,2);STICKLINE( CROSS(AA,BB),-8,15,1,0),COLORRED,LINETHICK2;STICKLINE( CROSS(AA,BB),1,6,1,0),COLOR00FFFF,LINETHICK2;DRAWICON(CROSS(AA,BB),13,13);STICKLINE( CROSS(BB,AA),108,85,1,0),COLOR00FF00,LINETHICK2;STICKLINE( CROSS(BB,AA),94,99,1,0),COLORFF00FF,LINETHICK2;DRAWICON(CROSS(BB,AA),85,14);

解答：

VAR1:=(2*C+H+L)/4;
