KDJ指标发出的信号太频繁，不够准确。请高手帮助编写一个MT4慢速KD指标。 原理就是，将原来的K值，再进行一次SMA取值，然后将这个SMA过的K值作为“慢速K”值。并且在数值80，20的位置，分别标出上、下轨虚线。 数值标尺：REFLINE: 0, 20, 40, 60, 80, 100; RSV:= (CLOSE-LLV(LOW,N))/(HHV(HIGH,N)-LLV(LOW,N))*100; K值:=SMA(RSV,M1,1); 显示指标： 慢速K:SMA(K值,M2,1); 慢速D:SMA(慢速K,M3,1); 上轨:90; 下轨:20;EUR.gif

第一个参数是N参数，第二个是平常的K参数，第三个是慢速K参数，第四个是慢速D参数。 你自己用编辑器编译一下，还有问题再讨论。如果不会我再传编译过的文件。 //+------------------------------------------------------------------+ //| SLOWKD.mq4 | //| Copyright ?2005, MetaQuotes Software Corp. | //| http://www.metaquotes.net | //+------------------------------------------------------------------+ #property copyright "Copyright ?2005, MetaQuotes Software Corp." #property link "http://www.metaquotes.net" #property indicator_separate_window #property indicator_buffers 2 #property indicator_color1 Silver #property indicator_color2 Yellow //---- input parameters extern int NPeriod=9; extern int KPeriod=3; extern int SKPeriod=3; extern int SDPeriod=3; double ind_buffer1; double ind_buffer2; double ind_buffer3; double ind_buffer4; double HighesBuffer; double LowesBuffer; int draw_begin1=0; int draw_begin2=0; //+------------------------------------------------------------------+ //| expert initialization function | //+------------------------------------------------------------------+ int init() { string short_name; //---- 2 additional buffers are used for counting.
