請問我平時在MT4裡有使用KDJ指標，現在想把它帶入MT3使用，要怎麼用呢? 編碼如下: #property indicator_separate_window #property indicator_buffers 3 #property indicator_color1 GreenYellow #property indicator_color2 Red #property indicator_color3 Green #property indicator_level1 0 #property indicator_level2 20 #property indicator_level3 80 #property indicator_level4 100 //---- input parameters extern int nPeriod=9; extern double factor_1=0.6666666; extern double factor_2=0.3333333; //---- buffers double percentK; double percentD; double percentJ; double RSV; //+------------------------------------------------------------------+ //| Custom indicator initialization function | //+------------------------------------------------------------------+ int init() { IndicatorBuffers(4); //---- indicators SetIndexStyle(0,DRAW_LINE); SetIndexBuffer(0,percentK); SetIndexLabel(0, "%K"); SetIndexStyle(1,DRAW_LINE); SetIndexBuffer(1,percentD); SetIndexLabel(1, "%D"); SetIndexStyle(2,DRAW_LINE); SetIndexBuffer(2,percentJ); SetIndexLabel(2, "%J"); SetIndexBuffer(3,RSV); //---- return(0); } //+------------------------------------------------------------------+ //| Custom indicator deinitialization function | //+------------------------------------------------------------------+ int deinit() { //---- //---- return(0); } //+------------------------------------------------------------------+ //| Custom indicator iteration function | //+------------------------------------------------------------------+ int start() { int counted_bars=IndicatorCounted(); //---- int i, k, num; double Ln, Hn, Cn; //---- i = Bars - counted_bars - 1; num = Bars - nPeriod; while(i>=0) { Cn = iClose(NULL,0,i); Ln = iClose(NULL,0,i); Hn = iClose(NULL,0,i); for(k=0; k iLow(NULL,0,i+k)) Ln = iLow(NULL,0,i+k); if (Hn < iHigh(NULL,0,i+k)) Hn = iHigh(NULL,0,i+k); } if (Hn-Ln != 0) RSV = (Cn-Ln)/(Hn-Ln)*100; else RSV = 50; if (i >= num) { percentK = factor_1 * 50 + factor_2 * RSV; percentD = factor_1 * 50 + factor_2 * percentK; } else { percentK = factor_1 * percentK[i+1] + factor_2 * RSV; percentD = factor_1 * percentD[i+1] + factor_2 * percentK; } percentJ = 3 * percentD - 2 * percentK; i--; } //---- return(0); } //+------------------------------------------------------------------+ 打開MT3的語言編輯器，到Drawing Custom indicator program properties這部分時，不知道要如何選擇，麻煩指點。 之後是貼上代碼儲存即可吧? 謝謝!

请大神详解一下，感激感谢~
