在论坛上看了下，关于同花顺趋势画线主图基本没有，不过通信达的一些主图公式同花顺也能用，自己整理二个：
一：
N:=27;
DRAWLINE(H=PEAK(1 ,N ,1 ) ,H ,L=TROUGH(2 ,N ,1 ) ,L , 1),COLOR66BB00;
DRAWLINE(H=PEAK(1 ,N ,1 ) ,H ,L=TROUGH(2 ,N ,1 ) ,L+(PEAK(1 ,N ,1 )-TROUGH(2 ,N ,1 ))/3 , 1),COLOR66BB00;
DRAWLINE(H=PEAK(1 ,N ,1 ) ,H ,L=TROUGH(2 ,N ,1 ) ,L+(PEAK(1 ,N ,1 )-TROUGH(2 ,N ,1 ))/3*2 , 1),COLOR66BB00;

DRAWLINE(L=TROUGH(2 , 30,1 ) ,L ,H=PEAK(1 ,30 ,1 ) ,H ,1 ),COLOR0099FF;
DRAWLINE(L=TROUGH(2 , 30,1 ) ,L ,H=PEAK(1 ,30 ,1 ) ,H-(PEAK(1 ,30 ,1 )-TROUGH(2 , 30,1 ))/3*2 ,1 ),COLOR0099FF;
DRAWLINE(L=TROUGH(2 , 30,1 ) ,L ,H=PEAK(1 ,30 ,1 ) ,H-(PEAK(1 ,30 ,1 )-TROUGH(2 , 30,1 ))/3 ,1 ),COLOR0099FF;
-----------------------------------------------------------------------------------------------------------
二：
DRAWLINE(C=HHV(C,60),HHV(H,3),C=HHV(C,30) AND C<HHV(C,45),HHV(HIGH,3),1),coloryellow;
DRAWLINE(HIGH>=HHV(HIGH,30),HIGH,LOW<=LLV(LOW,10),HHV(HIGH,6),1),COLORFFCCCC;
AB:DRAWLINE(HIGH>=HHV(HIGH,10),HIGH,LOW<=LLV(LOW,3),HHV(HIGH,3),1),coloryellow;
DRAWLINE(LOW<=LLV(LOW,120),LOW,HHV(H,6)<=HHV(H,10),LLV(LOW,6),1),colorblue;
VA11:=HIGH>=HHV(HIGH,60);
V1:=(REF(VA11,1)>0 AND VA11<1);
VA12:=LOW<=LLV(LOW,60);
V2:=REF(VA12,1)>0 AND VA12<1;
DRAWLINE(V2,LOW,V1,LLV(LOW,6),1),COLOR0099FF;
DRAWTEXT(CROSS(C,AB),L*0.98,'B'),colorgray;
------------------------------------------------------------------------------------------------
效果如下图：
