Are you asking for FileWriteArray function?
Not really, because I'm exporting to a CSV file.
If it is only that small amount of elements why not just splice them to individuals omitting the array entries completely.
It's actually a huge amount of data, i.e. many columns. I bumped also with the 63 parameter limit of FilwWrite, so I had to rethink the export entirely.
The solution which works now for me:
void WriteData(string txt){
uint uresult=0;
if (txt!="\n") {
txt=txt + ";";
}
uresult=FileWriteString(file_handle, txt,StringLen(txt));
if (uresult<=0) {
Print("Error writing to CSV file");
uint uresult=0;
if (txt!="\n") {
txt=txt + ";";
}
uresult=FileWriteString(file_handle, txt,StringLen(txt));
if (uresult<=0) {
Print("Error writing to CSV file");
}
return;
}
file_handle=FileOpen(DirectoryName+"//"+FileName,FILE_READ|FILE_WRITE|FILE_BIN);
// Write header:
WriteData("Symbol");
WriteData("OrderType");
WriteData("Lot");
WriteData("Open");
WriteData("Low");
.... // lots of more columns here
WriteData("\n");
.....
// then write data ...
output:
Symbol;OrderType;Lot;Open;Low;...
DE30;BUY;1.00;10629.81;10520.77;...
DE30;BUY;1.00;10629.81;10520.77;...

Hi, how can I dynamically build a parameter list for FileWrite? The number of columns is always the same, as I have a few loops through all timeframes, but I really want the loops. I suppose, the code will become ugly if I start the following:
FileWrite(file_handle, par1, par2, par3, arrayvalue[0], arrayvalue[1], arrayvalue[2]);
My ideal code would fill the parameter list right out of the loop for arrayvalue. Would that be possible?
