把压力支撑出现红箭头做个选股公式

编写要求：

HIGHN:=10;LOWN:=10;HIGHDISPLAY:=0;LOWDISPLAY:=0;ZGDISPLAY:=0;MADISPLAY:=0;AA:=REF(H,HIGHN)=HHV(H,2*HIGHN+1);QY:=BACKSET(AA,HIGHN+1);CC:=FILTER(QY,HIGHN) AND H=HHV(H,HIGHN+1);DRAWICON(CC,H*1.02,2);DDD:=BARSLAST(CC);GDTS:=IF(CC,CURRBARSCOUNT,0);DINGBU:=IF(DDD,REF(H,DDD),H);{顶部}DINGBUTS:=IF(DDD,REF(GDTS,DDD),GDTS);DINGBU1:=REF(DINGBU,DDD+1);GDCS1:=CONST(DINGBUTS);DINGBUTS1:=REF(DINGBUTS,DDD+1);GDCS2:=CONST(DINGBUTS1);DINGBU2:=REF(DINGBU1,DDD+1);MM:=IF(CURRBARSCOUNT>GDCS2,0,1);高点压力:DRAWLINE(CURRBARSCOUNT=GDCS2,H,CURRBARSCOUNT=GDCS1,H,1) COLORGREEN,LINETHICK2;DRAWLINE(CURRBARSCOUNT=GDCS2,H,ISLASTBAR,REF(H,GDCS2-1),1),COLOR0055FF,POINTDOT;DRAWLINE(CURRBARSCOUNT=GDCS1,H,ISLASTBAR,REF(H,GDCS1-1),1),COLORYELLOW,POINTDOT;AA1:=REF(L,LOWN)=LLV(L,2*LOWN+1);QY1:=BACKSET(AA1,LOWN+1);CC1:=FILTER(QY1,LOWN) AND L=LLV(L,LOWN+1);DRAWICON(CC1,L*0.98,1);DD1:=BARSLAST(CC1);DDTS:=IF(CC1,CURRBARSCOUNT,0);YDB:=IF(DD1,REF(L,DD1),L);DDTS1:=IF(DD1,REF(DDTS,DD1),DDTS);DDCS1:=CONST(DDTS1);ZDB:=REF(YDB,DD1+1);DDTS2:=REF(DDTS1,DD1+1);DDCS2:=CONST(DDTS2);低点支撑:DRAWLINE(CURRBARSCOUNT=DDCS2,L,CURRBARSCOUNT=DDCS1,L,1) COLORRED,LINETHICK2;

解答：

 LOWN:=10;
