一个找底很准公式(低位很准)

LC:=REF(CLOSE,1);
RSI1:=SMA(MAX(CLOSE-LC,0),6,1)/SMA(ABS(CLOSE-LC),6,1)*100;
AR:=SUM(HIGH-OPEN,26)/SUM(OPEN-LOW,26)*100;
卖点:=CROSS(85,RSI1)*30,COLOR00FF00,LINETHICK2;
VARB:=SMA(MAX(CLOSE-LC,0),7,1)/SMA(ABS(CLOSE-LC),7,1)*100;
VARC:=SMA(MAX(CLOSE-LC,0),13,1)/SMA(ABS(CLOSE-LC),13,1)*100;
VARD:=BARSCOUNT(CLOSE);
低位买点:(VARB< 20 AND VARC< 25 AND VARD> 50 AND AR<70)*200,LINETHICK2,COLOR00FF00;
BT1:=CROSS(RSI1,25);
主力:=EMA( (CLOSE-MA(CLOSE,7))/MA(CLOSE,7)*480,2)*5,LINETHICK1,COLOR0000FF;
小股民:EMA( (CLOSE-MA(CLOSE,11))/MA(CLOSE,11)*480,7)*5,LINETHICK2,COLORA607C0;
BT2:=CROSS(主力,小股民) AND 主力<-10;
BT:=FILTER(COUNT(BT1 OR BT2,3)>=2,3);
买:IF(BT2,200,0),STICK,COLOR0000FF,LINETHICK3;
