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)*1.01ANDREF(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。
