就是在原来的kdj指标基础上将原来的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 只是我的指标是多了个J值。我不懂MT4公式编译，不知道怎么加上去。 在此说声谢谢了。 公式如下： x:20,COLOR00BF00; s:80,COLORFFA500; RSVA:= (CLOSE-LLV(LOW,N))/(HHV(HIGH,N)-LLV(LOW,N))*100; FASTKA:=SMA(RSVA,M1,1); K:SMA(FASTKA,M1,1),COLOR0000FF; D:SMA(K,M1,1),COLOR00FF00; A:=3*K-2*D; J:EMA(A,M2); 参数 N 1 100 12 M1 1 100 3 M2 1 100 3 以下是论坛上hawkie
老师编写的慢速kd公式，只是我的指标是多了个J值。不知道怎么加到下面那些代码里，请哪位老师帮助帮助，在此先道声谢谢了 //+------------------------------------------------------------------+ //| SLOWKD.mq4 | //| Copyright ?2005, MetaQuotes Software Corp. | //| | //+------------------------------------------------------------------+ #property copyright "Copyright ?2005, MetaQuotes Software Corp." #property link "" #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.
