How to create a file

[luo jun]

 void OnTick()

{

  string FileName = TerminalInfoString(TERMINAL_DATA_PATH)+"\\"+"abc.txt";

  if(MyHandle == 0)

  {

    Print(FileName);

    MyHandle=FileOpen(FileName,FILE_WRITE|FILE_TXT);

    Print("MyHandle:",MyHandle);

  }

  

  if(MyHandle > 0)

  {

    FileWrite(MyHandle, string(AccountEquity()));

    FileClose(MyHandle);     

  } 

 

The log shows bellow info. And the error code is 5002. Whats the problem? 

EURUSDpro,M5: D:\MetaTrader 4\abc.txt

EURUSDpro,M5: MyHandle:-1
