Output to File using chart data

Hi there,

I'm looking for something that could output the chart data to file.

Let's take the EUR/USD 1HR chart for example - On this chart I have
the MACD set up with two MA.

What needs to be output to a file is the current/previous data on
the MACD, MA, High, Low, Open, Close.

If I were to apply other indicators then it would output that information.
I'm just looking for some quick example of how to do it the rest I should
be able to handle myself.

Thanks

Xantor,

There are scripts and indicators in these threads (here and here) that output OHLC, and could be easily modified to include MAs and MACD outputs.

hello xantor,

are you wanting to save this data, as it happens, in realtime?

i will need to know more about your indicators that you wish to use, i will require specifics.

either way, when you want to save information to a file, either from an indicator or from an ea, the standard way to do this is to use the basic file input/output functions that are built in to the platform's language..

Inserted Code
filehandle=FileOpen("myfile.txt",FILE_CSV|FILE_WRITE|FILE_READ,32);
FileSeek(filehandle,0,SEEK_END);
FileWrite(filehandle,Bid,Ask);
FileClose(filehandle);

above is an example of how one might save information to a file. you may change the above code for yourself, or you might just give to me the specifics about which indicators that you are using and then i will roll it all up for you.

data that is saved using the above file input/output functions will be saved to the /experts/files subdirectory, relative to the root subdirectory where you installed your metatrader platform.

No not real time but the previous bar and then it would update the file as a new bar completes.

So in actual fact not Tick based but Bar based. For now it just needs to append to a file the OHLC and the date and time.

The rest I should be able to handle in terms of indicators.

At the moment I am looking into hanover's posts he referred me to. I'm currently modifying one for my purposes although I'm struggling with the part to make it only report on a new bar.

Ok, made it so that it reports on new bars -=phew=- don't laugh

dont worry, i am not laughing, i enjoy helping others write code....

perhaps try this:

Inserted Code
#property indicator_chart_window
int init()
{
return(0);
}
int deinit()
{
return(0);
}
 
int start()
{
int now,then;
now=iTime(Symbol(),PERIOD_M1,0);
then=GlobalVariableGet("then");
if(now!=then) 
{
Print("bar changed!");
GlobalVariableSet("then",now);
//...the bar just changed...
//...execute whatever code that you need to here..
}/*if*/
return(0);  
}//start

Thank you it works like a charm!

Thanks for all the help guys.
Posting this here for anyone else who might need this as well for some reason.

Also feel free to point out if I made any mistakes
And I will be adding a function to detect last written data and append all data in between the last point and current -1...
