高低点连线指标 (文华财经)

老师，当高点比高点高，低点也比低点高时，当这2个条件同时成立时，ab划一条直线，cd也划一条直线，要如何写？

M:=1;
DIFF := EMA(CLOSE,12*M) - EMA(CLOSE,26*M);
DEA  := EMA(DIFF,9*M);
MACD:=2*(DIFF-DEA),COLORSTICK;
J:=CROSS(DIFF,DEA),NODRAW;
S:=CROSSDOWN(DIFF,DEA),NODRAW;
HH:=CROSS(EVERY(MACD>0,5*M),0.5),NODRAW;
LL:=CROSS(EVERY(MACD<0,5*M),0.5),NODRAW;
//HH:=CROSS(EVERY(DIFF>0,5),0.5),NODRAW;
//LL:=CROSS(EVERY(DIFF<0,5),0.5),NODRAW;
AA:=COUNT(HH,BARSLAST(LL)+1)=1&&HH,NODRAW;
BB:=COUNT(LL,BARSLAST(HH)+1)=1&&LL,NODRAW;
T1:=BACKSET(REFX(AA,15),LLVBARS(L,BARSLAST(REFX(BB,15))+1)+1);
T2:=BACKSET(REFX(BB,15),HHVBARS(H,BARSLAST(REFX(AA,15))+1)+1);
DRAWLINE1(CROSS(T1,0.5),L,CROSS(T2,0.5),H,0),COLORGREEN,LINETHICK2;
DRAWLINE1(CROSS(T2,0.5),H,CROSS(T1,0.5),L,0),COLORRED,LINETHICK2;
GG:=VALUEWHEN(CROSS(T2,0.5),H);
DD:=VALUEWHEN(CROSS(T1,0.5),L);
