本人一直在用的指标公式，底部跟波段高低很好抓！！简单明了！！
 

主图

A:=AMOUNT/V/100;
VARA:=EMA((((A-EMA(A,13))/EMA(A,13))*(0-100)),5);
操盘线:=EMA(((VARA/10)+EMA(A,10)),3);
行情线:=EMA(A,3);
重心:=(C+0.618*REF(C,1)+0.382*REF(C,2)+0.236*REF(C,3)+0.146*REF(C,4))/2.382;
STICKLINE(行情线<操盘线,H,L,0,1),COLORGREEN;
STICKLINE(行情线<操盘线,C,O,2,1),COLORGREEN;
STICKLINE(行情线>=操盘线,H,L,0,1),COLORRED;
STICKLINE(行情线>=操盘线,C,O,2,1),COLORRED;
{压力支撑线}
{顶底信号}
DRAWTEXT(CROSS(行情线,操盘线),L*0.98,'★B'),COLORGRAY;
JH:=SMA(MAX(C-REF(C,1),0),5,1)/SMA(ABS(C-REF(C,1)),5,1)*100;
