公式如下：
V1:=LLV(LOW,10);
V2:=HHV(HIGH,30);
价格线:EMA(((CLOSE-V1)/(V2-V1))*(100),4),COLORGREEN;
IF(价格线> REF(价格线,1)*1.01,价格线 ,DRAWNULL),COLORRED;
IF(价格线< REF(价格线,1),价格线 ,DRAWNULL),COLORBLUE;
VAR06:=(2*CLOSE+HIGH+LOW)/4;
VAR07:=LLV(LOW,13);
DRAWTEXT_FIX(C>O,0.01,0.9,0,’：水鸭的投资日记’),COLORRED;
VAR08:=HHV(HIGH,13);
VAR09:=EMA((VAR06-VAR07)/(VAR08-VAR07)*100,13);
VARA1:=EMA(0.667*REF(VAR09,1)+0.333*VAR09,2);
{A:VAR9-50;
B:VARA1-50;
STICKLINE(A> B,A,B,2,0),COLORRED;
STICKLINE(A<= B,A,B,2,0),COLORGREEN;
0,COLORRED;}
STICKLINE(VAR09> VARA1,VAR09,VARA1,3,0),COLORRED;
STICKLINE(VAR09<= VARA1,VAR09,VARA1,3,0),COLORGREEN;
80,COLORRED,DOTLINE;
20,,COLORGREEN,DOTLINE;
DRAWTEXT(ISLASTBAR,80,’顶点’),COLORRED;
DRAWTEXT(ISLASTBAR,20,’低点’),COLORGREEN;
DRAWTEXT_FIX(1,0,0,0,’ A – 见红-逢低买入 ’),COLORRED;
DRAWTEXT_FIX(1,0.14,0,0,’ B – 见绿警示-逢高减仓 ’),COLORGREEN;
DRAWTEXT_FIX(1,0.28,0,0,’ C – 见蓝风险-高抛避险 ’),COLORCYAN;
观察：
似乎“由绿转红”时，会有一段行情，就用这个做选股公式吧
选股公式如下
V1:=LLV(LOW,10);
V2:=HHV(HIGH,30);
价格线:=EMA(((CLOSE-V1)/(V2-V1))*(100),4);
价格线> REF(价格线,1)*1.01 AND REF(价格线,1)
测试一下，平仓规则是，不论盈亏，以持股5天后平仓为条件。
