【】【】【】波段高低

 可加在任何主图中的高低点源码：

TC1:=IF(H=HHV(H,48),H,DRAWNULL);
TC2:=CONST(BARSLAST(TC1=H))+1;
UPPER:=CONST(IF(TC2=1,H,REF(H,TC2-1)));
BC1:=IF(L=LLV(L,48),L,DRAWNULL);
BC2:=CONST(BARSLAST(BC1=L))+1;
LOWER:=CONST(IF(BC2=1,L,REF(L,BC2-1)));
LP:=CURRBARSCOUNT<=BC2 AND L=LOWER;{低点定位}
HP:=CURRBARSCOUNT<=TC2 AND H=UPPER;{高点定位};
DRAWICON(IF(LP,1,0),L*0.95,18);
DRAWTEXT(LP,L*0.995,'↖波段底'),COLORMAGENTA;
DRAWICON(IF(HP,1,0),H*1.02,15);
DRAWTEXT(HP,H*1.01,'←波段顶'),COLORGREEN;

 

 

本源码选股公式：

BC1:=IF(L=LLV(L,48),L,DRAWNULL);
BC2:=CONST(BARSLAST(BC1=L))+1;
LOWER:=CONST(IF(BC2=1,L,REF(L,BC2-1)));
LP:CURRBARSCOUNT<=BC2 AND L=LOWER;
