Simple Expert Adviser with filewrite operation

Hello all the gurus!!
I wrote a simple and straight EA


string filename;

int handle;
//+------------------------------------------------------------------+
//| Custom indicator initialization function |
//+------------------------------------------------------------------+
int init()
{
//---- indicators
filename = "myfile.csv";
handle = FileOpen(filename,FILE_CSV|FILE_WRITE);
return(0);
}

//+------------------------------------------------------------------+
//| Custom indicator deinitialization function |
//+------------------------------------------------------------------+
int deinit()
{
//----
FileClose(handle);


//----
return(0);
}
//+------------------------------------------------------------------+
//| Custom indicator iteration function |
//+------------------------------------------------------------------+
int start()
{


int handle = FileOpen(filename,FILE_CSV|FILE_WRITE|FILE_READ);

if (FileWrite(handle,"yy")<0)
{Print("error writing file");}
else
{Print("filewrite time successful @ ");}
FileClose(handle);




return(0);
}
//+----------

I expect it to write ""yy" into a file |expertsfilesmyfile.csv and thought EA runs (icon smiles), I don't have any output, even a file is not created inside expertfile directory.
Could anyone comment on what I miss here?
Your help would be much appreciated indeed!
Thank you!

You have to realize that this is an EA and not script. The start() function gets called for every tick and you opening the file, writing to it and closing the file for every tick. Its quite possible that you have overwhelmed the I/O system with calls.

Even if it were working, it would not produce any useful output using the current logic. There are several ways to fix the problem depending on what you are trying to accomplish. I'm not sure what your intention was, so it is difficult to know what to tell you. So once you tell us what you want, we can give you the answer.

you are opening the same file twice -- get rid of the fileopen and fileclose in the init ad deinit funcs, and it should work. Or, even better, leave them there and delete the fileopen and fileclose from the start() func..

This guy was able to come up with an EA solution that did updates every 5 minutes. Should be easy to adapt his code.

Thank all of you guys, that info helps me a lot!!
I will use that approach with EA and a new bar on a chart as a trigger for file operation.
Thank you again!
