前面十天缩量今天倍量的选股公式
{地量倍量}
{设计原理：选出昨日成交量为百日内地量，今天成交量是昨天成交量一倍以上}
T1:=REF(VOL,1)=LLV(V,100); T2:=V/T1>1.95;
T3:=C>O AND C>REF(C,1); 选股:T1 AND T2 AND T3; {黄金柱}
CTX:=(3*C+H+L+O)/6;
IONG:=(8*CTX+7*REF(CTX,1)+6*REF(CTX,2)+5*REF(CTX,3)+4*REF(CTX,4)+3*REF(CTX,5)+2*REF(CTX,6)+REF(CTX,8))/36;CTXIONG:=VOL=HHV(VOL,20)AND VOL>2*REF(VOL,1)AND CLOSE>IONG AND C>REF(C,1);XG:FILTER(CTXIONG,5);
{倍缩量}
低量:=LLV(VOL,34)=ref(VOL,3); 倍缩量:=ref(VOL,3)/REF(VOL,4)<0.5; 低量and倍缩量; {不跌回}
{成交量比前一天放大1倍,后3天,股价没有跌破放量那天的收
盘价}
var1:=v>ref(v,1)*2;ref(var1,3)and count(c> ref(c,3),3)=3; {突破前高}
SR1:=REF(HIGH,10)=HHV(HIGH,2*10+1); SR2:=FILTER(SR1,10); SR3:=BACKSET(SR2,10+1); HD:=FILTER(SR3,10); 前高:=REF(H,BARSLAST(HD));
倍量:=VOL/REF(VOL,1)>=2 AND COUNT(CLOSE>OPEN,1)OR LOW>REF(HIGH,1)
AND COUNT(OPEN>CLOSE,1)AND VOL/REF(VOL,1)>=2; 突破前高:CROSS(C,前高)and倍量; {真黄金柱}
{倍量柱加三天量减价升喇叭形的真黄金柱} T1:=count(v>ref(v,1)*2,4)=1;
t2:=count(vmin(l,4)and l>ref(l,1),3)=3; t3:t1 and t2;
