Error 5011 - File is Empty

anuj71 2024.03.01 03:24

Hello,

I am trying to store one small value into file.

Simple, Rule

If file exist, read the value else create new file and store the value

When OnTick condition executed, Rewrite the value.

But i am getting an error 5011 and when i open the .txt file, it always empty and blank. How to solve this?

extern string inc_MoneyManagement = "***Money Management***";
extern bool Money_Management = FALSE;
enum MoneyManagement_enum {Fixed_Money, Balance_Percentage};
extern MoneyManagement_enum MoneyManagement_Type = Balance_Percentage;
extern double Target_Revenue = 1000.0;
double gTargeted_Revenue;

// File to store gTargeted_Revenue value
string MM_File = _Symbol+"targeted_revenue.txt";

int OnInit() {
   // Load gTargeted_Revenue value from file if it exists
   int fileHandle = FileOpen(MM_File, FILE_READ);
   if (fileHandle != INVALID_HANDLE) {
      gTargeted_Revenue = FileReadDouble(fileHandle);
      FileClose(fileHandle);
      Print("Loaded gTargeted_Revenue from file: ", gTargeted_Revenue);
   } else {
      // Create a new file and calculate gTargeted_Revenue
      ResetLastError();
      fileHandle = FileOpen(MM_File, FILE_WRITE);
      if (fileHandle != INVALID_HANDLE) {
         if(MoneyManagement_Type == Balance_Percentage)
            gTargeted_Revenue = (1 + Target_Revenue/100) * AccountBalance();
         else
            gTargeted_Revenue = Target_Revenue + AccountBalance();

         FileWriteDouble(fileHandle, gTargeted_Revenue);
         FileClose(fileHandle);
         Print("Created new file and wrote gTargeted_Revenue: ", gTargeted_Revenue);
         Print(" File creation Error : " + GetLastError());
      } else {
         Print("Failed to create file: ", MM_File);
         // Handle file creation failure here
      }
   }
}


void OnTick() {
   if(Money_Management && AccountEquity() >= gTargeted_Revenue) {
      for (int i = OrdersTotal() - 1; i >= 0; i--) {
         if (OrderSelect(i, SELECT_BY_POS)==false) continue;
         if (OrderClose(OrderTicket(), OrderLots(), OrderClosePrice(), 3, clrNONE) == false)
            Print("Order close failed for ticket ", OrderTicket());
      }

      Print("All The Trade Closed due to it exceeded defined Money Management (Target Revenue) : " + AccountEquity());

      // Update gTargeted_Revenue value
      if(MoneyManagement_Type == Balance_Percentage)
         gTargeted_Revenue = (1 + Target_Revenue/100) * AccountBalance();
      else
         gTargeted_Revenue = Target_Revenue + AccountBalance();

      // Save gTargeted_Revenue value to file
      int fileHandle = FileOpen(MM_File, FILE_WRITE);
      if (fileHandle != INVALID_HANDLE) {
         FileWriteDouble(fileHandle, gTargeted_Revenue);
         FileClose(fileHandle);
      } else {
         Print("Failed to open file for writing: ", MM_File);
         // Handle file writing failure here
      }
   }
}

Have you ever checked what the error code means?

You need to check your file extension and your opening flags such that they coincide. A .bin file needs to be opened as binary, a txt or CSV file need to be opened as text or csv file...

There are some undocumented limitations, and I am not sure since when they exist.

I have already seen that URL and some forum post but still i did not understand how can i code this. Can you help with sample code or more explanation, how can i achieve

You need to add a flag to specify the file type

FileOpen(MM_File, FILE_READ |FILE_TXT );

https://www.mql5.com/en/docs/files/fileopen

EDIT:

I think FileWriteDouble requires a binary file type.

If you want a text file, you need to convert the double to a string and then write the string to the text file.

All i need to add FILE_TXT with FileOpen?

Like this FILE_READ | FILE_TXT and FILE_WRITE | FILE_TXT?

extern string inc_MoneyManagement = "***Money Management***";
extern bool Money_Management = FALSE;
enum MoneyManagement_enum {Fixed_Money, Balance_Percentage};
extern MoneyManagement_enum MoneyManagement_Type = Balance_Percentage;
extern double Target_Revenue = 1000.0;
double gTargeted_Revenue;

// File to store gTargeted_Revenue value
string MM_File = _Symbol+"targeted_revenue.txt";

int OnInit() {
   // Load gTargeted_Revenue value from file if it exists
   int fileHandle = FileOpen(MM_File, FILE_READ |FILE_TXT);
   if (fileHandle != INVALID_HANDLE) {
      gTargeted_Revenue = FileReadDouble(fileHandle);
      FileClose(fileHandle);
      Print("Loaded gTargeted_Revenue from file: ", gTargeted_Revenue);
   } else {
      // Create a new file and calculate gTargeted_Revenue
      ResetLastError();
      fileHandle = FileOpen(MM_File, FILE_WRITE |FILE_TXT);
      if (fileHandle != INVALID_HANDLE) {
         if(MoneyManagement_Type == Balance_Percentage)
            gTargeted_Revenue = (1 + Target_Revenue/100) * AccountBalance();
         else
            gTargeted_Revenue = Target_Revenue + AccountBalance();

         FileWriteDouble(fileHandle, gTargeted_Revenue);
         FileClose(fileHandle);
         Print("Created new file and wrote gTargeted_Revenue: ", gTargeted_Revenue);
         Print(" File creation Error : " + GetLastError());
      } else {
         Print("Failed to create file: ", MM_File);
         // Handle file creation failure here
      }
   }
}


void OnTick() {
   if(Money_Management && AccountEquity() >= gTargeted_Revenue) {
      for (int i = OrdersTotal() - 1; i >= 0; i--) {
         if (OrderSelect(i, SELECT_BY_POS)==false) continue;

            Print("Order close failed for ticket ", OrderTicket());
      }

      // Update gTargeted_Revenue value

See edit of my previous post, please.

You need to align the data types. The file type with the FileOpen flags, and the data you want to write to the file...

I have moved your thread, because error code 5011 only exists in MQL5, but you posted in MQL4 section.

Also, do a research about the keyword "extern", it has a different meaning in MQL5 than in MQL4.

I saw your code based on it. i made an edit and posted next to your post. Is my code is correct?

Yes, you are right, it's MQL4 as well... I've checked the wrong doc. It's one of those undocumented error codes. I moved the thread back to MQL4 section.

Please test end debug your code yourself, I am not sure about FileWriteDouble, as I think it requires a binary file...

Please refer to the documentation, everything is explained there for your needs.
