原理：三阴线过后，结合权重绝对值的算法。来定趋势，当趋势在相对的低位就是满足条件，发出信号！
事项：
抄底分为两种,一种为抄底，一种为整理回调抄底。这个指标处于两者之间，k线的形态，
A:=EVERY(OPEN>CLOSE,3);
A1:=C/REF(C,1)>1.03;
A2:=SMA(MAX(CLOSE-REF(C,1),0),2,1)*C*102;
A3:=SMA(ABS(CLOSE-REF(C,1)),2,1)*C*100;
A4:=A2/A3*100<10;
A5:=A AND A4;
A6:=MA(C,5)<REF(MA(C,5),1);
A7:=REF(MA(C,5),4)>REF(MA(C,5),5);
A8:=(H-C)/C*100<1 AND REF((O-C)/C*100>1,1) AND KDJ.J>25;
REF(A5,1) AND C>O AND A1 AND A6 AND A7 AND A8;
