 11 kerimhoroz 2015.09.08 23:14   Hello,I have been trying to integrate my calculation on eurusd chart. However, I could not find where I am mistaken. Would you help me out with my codes at below ? Or what do you suggest to have result as a line on EURUSD chart ?  Thanks.  ```// The code is being used for educational purpose only. //-------------------------------------------------------------------- #property indicator_chart_window    // Indicator is drawn in the main window #property indicator_buffers 1       // Number of buffers #property indicator_color1 Blue     // Color of the 1st line   double Buf_0   [];             // Declaring arrays (for indicator buffer)   double XAGUSD  [];             // symbol on mt4 of broker as an array   double USDTRY  [];             // symbol on mt4 of broker as an array   double EURTRY  [];             // symbol on mt4 of broker as an array   double USDJPY  [];             // symbol on mt4 of broker as an array   double USDCHF  [];             // symbol on mt4 of broker as an array   double USDCAD  [];             // symbol on mt4 of broker as an array   double GBPUSD  [];             // symbol on mt4 of broker as an array   double USDINDEX[];             // symbol on mt4 of broker as an array   double XAUUSD  [];             // symbol on mt4 of broker as an array   double SP500   [];             // symbol on mt4 of broker as an array   double DOW     [];             // symbol on mt4 of broker as an array   double DAX     [];             // symbol on mt4 of broker as an array       double FTSE    [];             // symbol on mt4 of broker as an array   double USOIL   [];             // symbol on mt4 of broker as an array    //-------------------------------------------------------------------- int init()                          // Special function init()   {    SetIndexBuffer(0,Buf_0);         // Assigning an array to a buffer    SetIndexStyle (0,DRAW_LINE,STYLE_SOLID,2);// Line style    return;                          // Exit the special funct. init()   } //-------------------------------------------------------------------- int start()                         // Special function start()   {    int i,                           // Bar index        Counted_bars;                // Number of counted bars //--------------------------------------------------------------------    Counted_bars=IndicatorCounted(); // Number of counted bars    i=Bars-Counted_bars-1;           // Index of the first uncounted    while(i>=0)                      // Loop for uncounted bars      {         XAGUSD[i]       = 1.6382+0.000245*MarketInfo("XAGUSD",MODE_ASK);  //ask price at i. bar         USDTRY[i]       = 0.25893*MarketInfo("USDTRY",MODE_ASK);          //ask price at i. bar         EURTRY[i]       = 0.22969*MarketInfo("EURTRY",MODE_ASK);          //ask price at i. bar         USDJPY[i]       = 0.000678*MarketInfo("USDJPY",MODE_ASK);         //ask price at i. bar         USDCHF[i]       = 0.02318*MarketInfo("USDCHF",MODE_ASK);          //ask price at i. bar         USDCAD[i]       = 0.07650*MarketInfo("USDCAD",MODE_ASK);          //ask price at i. bar             GBPUSD[i]       = 0.08350*MarketInfo("GBPUSD",MODE_ASK);          //ask price at i. bar           USDINDEX[i]     = 0.007118*MarketInfo("#DXU5",MODE_ASK);          //ask price at i. bar           XAUUSD[i]       = 0.050014*MarketInfo("XAUUSD",MODE_ASK);         //ask price at i. bar         SP500[i]        = 0.000019*MarketInfo("#ESU5",MODE_ASK);          //ask price at i. bar         DOW[i]          = 0.000002*MarketInfo("#YMU5",MODE_ASK);          //ask price at i. bar         DAX[i]          = 0.000001*MarketInfo("#FDXU5",MODE_ASK);         //ask price at i. bar         FTSE[i]         = 0.000001*MarketInfo("#FFIU5",MODE_ASK);         //ask price at i. bar         USOIL[i]        = 0.000031*MarketInfo("#CLV5",MODE_ASK);          //ask price at i. bar         Buf_0[i]        =     XAGUSD[i]-USDTRY[i]+EURTRY[i]+USDJPY[i]                              +USDCHF[i]+USDCAD[i]-GBPUSD[i]-USDINDEX[i]                              -XAUUSD[i]+SP500[i]-DOW[i]-DAX[i]                              +FTSE[i]-USOIL[i];             // Value of 0 buffer on i bar       i--;                          // Calculating index of the next bar      } //--------------------------------------------------------------------    return;                          // Exit the special funct. start()   } //--------------------------------------------------------------------```
