笔参数:=10; 
//设置笔参数为10周期

段参数:=6; 
//设置段参数为6周期

笔低A:=LOW<=LLV(LOW,笔参数),NODRAW; 
//笔低A条件：当前最低价是笔参数周期内最低值(不绘制)

笔高A:=HIGH>=HHV(HIGH,笔参数),NODRAW; 
//笔高A条件：当前最高价是笔参数周期内最高值(不绘制)

笔低:=笔低A AND 笔高A=0,NODRAW; 
//笔低条件：满足笔低A且不满足笔高A(不绘制)

笔高:=笔高A AND 笔低A=0,NODRAW; 
//笔高条件：满足笔高A且不满足笔低A(不绘制)

VP1:=BACKSET(笔高,BARSLAST(笔低)+1); 
//VP1：从最近笔低点开始向后标记笔高点

VP2:=BACKSET(笔低,BARSLAST(笔高)+1); 
//VP2：从最近笔高点开始向后标记笔低点

VP3:=(笔低A AND VP2 AND VP1) OR (CROSS(BACKSET(BARSTATUS=2,BARSLAST(笔低A)+1),0.5)); 
//VP3条件：(满足笔低A且VP2和VP1)或(最后一个K线是笔低点)

VP4:=(VP1 AND 笔高A AND VP2) OR (CROSS(BACKSET(BARSTATUS=2,BARSLAST(笔高A)+1),0.5)); 
//VP4条件：(满足VP1且笔高A和VP2)或(最后一个K线是笔高点)

DRAWLINE1(VP3,LOW,VP4,HIGH,0),COLORLIGHTRED,LINETHICK2; 
//绘制红色线段：从VP3低点到VP4高点

DRAWLINE1(VP4,HIGH,VP3,LOW,0),COLORLIGHTGREEN,LINETHICK2;  
//绘制绿色线段：从VP4高点到VP3低点

T1:=BACKSET(ISLASTBAR,SUMBARS(VP3||VP4,2)); 
//T1：标记最后两个VP3或VP4点

DRAWSL(CROSS(T1,0.5) && VP3,VALUEWHEN(VP4,HIGH),0,-SUMBARS(VP4,1)+1,0,COLORRED),LINETHICK2; 
//绘制红色趋势线：从VP3点开始，参考VP4高点

DRAWSL(CROSS(T1,0.5) && VP3,LOW,0,-SUMBARS(VP4,1)+1,0,COLORRED),LINETHICK2; 
//绘制红色趋势线：从VP3低点开始

DRAWSL(CROSS(T1,0.5) && VP3,LOW+0.382*(VALUEWHEN(VP4,HIGH)-LOW),0,-SUMBARS(VP4,1)+1,0,COLORRED),LINETHICK2;

//绘制红色趋势线：从VP4高点开始

DRAWSL(CROSS(T1,0.5) && VP4,VALUEWHEN(VP3,LOW),0,-SUMBARS(VP3,1)+1,0,COLORRED); 
//绘制红色趋势线：从VP4点开始，参考VP3低点

DRAWSL(CROSS(T1,0.5) && VP4,VALUEWHEN(VP3,LOW)+0.382*(HIGH-VALUEWHEN(VP3,LOW)),0,-SUMBARS(VP3,1)+1,0,COLORRED);
