通达信指标求助,关于KDJ

写了个指标,如下:
{KDJ指标}
K1:=(KDJ.K),(81);
K2:=(KDJ.D),(3);
K3:=(KDJ.J),(3);
K4:=K3>100;
K5:=K3-REF(K3,1)<0;

KDJ卖出达标:K4 AND K5 ,COLORGREEN ;


我想实现,如果KDJ的指标,如果J值大于100,并且现在的J值比上一秒的J值小,提醒.
请大神帮忙.

{KDJ指标}
RSV:=(CLOSE-LLV(LOW,81))/(HHV(HIGH,81)-LLV(LOW,81))*100;
K:=SMA(RSV,3,1);
D:=SMA(K,3,1);
J:=3*K-2*D;
K4:=J>100;
K5:=J-REF(J,1)<0;
J>100 AND REF(J,1)>=REF(J,2) AND J<REF(J,1);
