KD指标求助

编写标准：求助教师写个kd指标；

K 值持续3天超过80出信号到80下列信号终止

K 值持续3天低于20出信号到20之上信号终止

RSV:=(CLOSE-LLV(LOW,N))/(HHV(HIGH,N)-LLV(LOW,N))*100;

K:SMA(RSV,M1,1);

D:SMA(K,M2,1);

通达信软件感谢老师了

编写方式：N:=9;M1:=3;M2:=3;

RSV:=(CLOSE-LLV(LOW,N))/(HHV(HIGH,N)-LLV(LOW,N))*100;

K:SMA(RSV,M1,1);

D:SMA(K,M2,1);

AA:=COUNT(K>80,3)=3;

BB:=COUNT(K<20,3)=3;

DRAWICON(AA,K*1.01,2),COLOR00FF00;

DRAWICON(BB,K*0.99,1),COLOR0000FF;
