Hi guys,

I am dealing with the same thing - open new chart (my code is correct) + open other EA on new chart (code no works valid)

Can you help me, please?

Code for open new chart:

#import "user32.dll"
   int GetAncestor(int hWnd, int gaFlags);
   int GetDlgItem(int hDlg, int nIDDlgItem);
   int PostMessageA(int hWnd, int Msg, int wParam, int lParam);
#import

#define WM_COMMAND   0x0111
#define WM_KEYDOWN   0x0100
#define VK_HOME      0x0024
#define VK_DOWN      0x0028

//+------------------------------------------------------------------+
//| script program start function                                    |
//+------------------------------------------------------------------+
// New charts opens from the "Market Watch" window with the DEFAULT.TPL template.
void start()
{   
ChartWindow("GOLD");
}

//+------------------------------------------------------------------+
//| Open a new chart                                                 |
//+------------------------------------------------------------------+
int ChartWindow(string SymbolName)
{
   int hFile, SymbolsTotal, hTerminal, hWnd;

   hFile = FileOpenHistory("symbols.sel", FILE_BIN|FILE_READ);
   if(hFile < 0) return(-1);

   SymbolsTotal = (FileSize(hFile) - 4) / 128;
   FileSeek(hFile, 4, SEEK_SET);

   hTerminal = GetAncestor(WindowHandle(Symbol(), PERIOD_M1), 2);

   hWnd = GetDlgItem(hTerminal, 0xE81C);
   hWnd = GetDlgItem(hWnd, 0x50);
   hWnd = GetDlgItem(hWnd, 0x8A71);

   PostMessageA(hWnd, WM_KEYDOWN, VK_HOME, 0);

   for(int i = 0; i < SymbolsTotal; i++)
   {
      if(FileReadString(hFile, 12) == SymbolName)
      {
         PostMessageA(hTerminal, WM_COMMAND, 33160, 0);
         return(0);
      }
      PostMessageA(hWnd, WM_KEYDOWN, VK_DOWN, 0);
      FileSeek(hFile, 116, SEEK_CUR);
   }

   FileClose(hFile);

   return(-1);
}

Code for insert EA on chart from this thread:

PostMessageA(hTerminal, WM_COMMAND, 33160, 0);
Sleep(500); // u should give some time to open the chart
int MessageNumber = RegisterWindowMessageA("MetaTrader4_Internal_Message");
PostMessageA(hTerminal, MessageNumber, 14, "myEA");

I cannot implementations this code. :-(

Thank you for help!!!
