今日天的《洗盘后反弹买点主图》，感觉不错，为了方便大家选股，做了个副图选股公式。原帖讲的很清楚，不再赘述

支撑线:(1-9/100)*MA(C,10),COLORYELLOW,LINETHICK2;

AAA:=(3*C+H+L+O)/6;
VAR1:(8*AAA+7*REF(AAA,1)+6*REF(AAA,2)+5*REF(AAA,3)+4*REF(AAA,4)+3*REF(AAA,5)+2*REF(AAA,6)+REF(AAA,8))/36,LINETHICK2,COLORRED;
IF((VAR1 <= REF(VAR1,1)),VAR1,DRAWNULL),COLORGREEN,LINETHICK3;
IF((VAR1 >= REF(VAR1,1)),VAR1,DRAWNULL),COLORRED,LINETHICK3;

RSV:=(CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100;
K:=SMA(RSV,2,1);
D:=SMA(K,2,1);
J:=3*K-2*D;
买入:=CROSS(J,0)AND(H>=支撑线);

DRAWICON(买入,LOW*0.95,25);

使用说明：
1：出信号时，支撑线走平或上翘最好！
2：红线是持线，出信号后线变红就一路持有，变绿就买出！
3：对于强势股，有时无信号，回调到支撑线处也是买点！
