今天给大家分享一个用于参考顶底的指标，由于在周线和月线级别准确率非常高，给股友们一个参考。

指标公式：

X_1:=6;
X_2:=4;
X_3:=13;
X_4:=(3*CLOSE+LOW+OPEN+HIGH)/6;
X_5:=WMA(VOL,X_3);
X_6:=WMA(AMOUNT,X_3);
X_7:=X_6/X_5/100;
X_8:=(X_4-X_7)/X_7*100;
短底:X_8<(-6),NODRAW,COLORWHITE;
中底:X_8<(-10),NODRAW,COLORYELLOW;
大底:X_8<(-14),NODRAW,COLORCYAN;
绝对底:X_8<(-18),NODRAW,COLORRED;
STICKLINE(X_8<0-18,30,40,0.51,0),COLORRED;
STICKLINE(X_8<0-14,20,30,0.51,0),COLORCYAN;
STICKLINE(X_8<0-10,10,20,0.51,0),COLORYELLOW;
STICKLINE(X_8<0-6,0,10,0.51,0),COLORWHITE;
风险线上高抛:80,DOTLINE,COLORGREEN;
机会线下低吸:20,DOTLINE,COLORCYAN;
X_9:=LLV(LOW,X_1);
X_10:=HHV(HIGH,X_1);
X_11:=WMA((X_4-X_9)/(X_10-X_9)*100,X_2);
DRAWNUMBER(X_11>=80,80,BARSLASTCOUNT(X_11>=80));
慢线:WMA(0.667*REF(X_11,1)+0.333*X_11,2),DOTLINE,COLORYELLOW;
X_12:=REF(X_11,1)>80 OR X_11>80;
X_13:=REF(X_11,1)<30 OR X_11<30;
DRAWICON(CROSS(慢线,X_11) AND X_12,50,2);
DRAWICON(CROSS(X_11,慢线) AND X_13,50,1);
趋势线:X_11,COLORMAGENTA;
IF(X_11>=REF(X_11,1),X_11,DRAWNULL),COLORRED,LINETHICK2;

公式讲解：当指标出现红线时表示股价将会有一段上升趋势，此时可以考虑入场（尤其是有红色箭头的时候）；当出现紫线时表面股价可能会有一段下降趋势，此时可以考虑出场。
