Is someone here know why this works:

Code

                            
Stream strm = Client.OpenRead("http://www.dailyfx.com/calendar/Dailyfx_Global_Economic_Calendar.csv?currentWeek=/events-calendar/2009/0913/&direction=none&collector=allInFolderDateDesc&view=week&timezone=GMT&currencyFilter=|&importanceFilter=Medium|Low|");

and this not:

Code

                            
string url_news="http://www.dailyfx.com/calendar/Dailyfx_Global_Economic_Calendar.csv?currentWeek=/events-calendar/2009/0913/&direction=none&collector=allInFolderDateDesc&view=week&timezone=GMT&currencyFilter=|&importanceFilter=Low|";
Stream strm = Client.OpenRead(url_news);

???

The only thing I can think of is that when specifying a path within a STRING variable you need to double up on the forward slash marks similiar to the backward slash marks.

Example: c:\\temp\\temp.txt <- this works in STRING variables

Try this:

Code

private string url_news="https:////www.dailyfx.com//calendar//Dailyfx_Global_Economic_Calendar.csv?currentWeek=//events-calendar//2009//0913/&direction=none&collector=allInFolderDateDesc&view=week&timezone=GMT&currencyFilter=|&importanceFilter=Low|;;[/URL]"

Thx guys, but it's finally working, don't ask me why...

Code

                            
            string year_news="2009";
            string month_news="09";
            string day_news="13";
            string filter_news="Medium|Low|"; //No Medium/Low importance news
            string url_news="http://www.dailyfx.com/calendar/Dailyfx_Global_Economic_Calendar.csv?";
            url_news=String.Concat(url_news,"currentWeek=/events-calendar/");
            url_news=String.Concat(url_news,year_news,"/",month_news,day_news,"/");
            url_news=String.Concat(url_news,"&direction=none&collector=allInFolderDateDesc&view=week&timezone=GMT&currencyFilter=|&importanceFilter=",filter_news);

            Stream strm = Client.OpenRead(url_news);
            StreamReader sr = new StreamReader(strm);

Here is a pre-Alpha version, not finished at all, but I think it's a good start, the logic is already there, I just need to add some parameters for sound, plot arrows instead of a line, for customizable reg exp, etc, etc.
This indicator gets the news from Forex News | Forex Trading News | Currency Trading News, parse them, then print a line X minutes before the news.
In the code, I only take High importance news, and for USD currency (see regex).

It seems to work fine on my minutes charts, but as I wrote, it's not a production release.

This sounds good sam. Can you make the news priority level configurable? I got sacked for 30 ticks on CL by an orange news release. From now on I pay attention to both orange & red!!

In the code posted above, just replace

Code

                            
string filter_news="Medium|Low|";

by

Code

                            
string filter_news="Low|";

And for filtering by currencies, until I've added some customizable parameterd, you'll have to play with

Code

                            
Regex r1 = new Regex("^EUR");

. In this example, we only get the news which concerns EUR.
I'm getting and parsing a csv file downloaded here, and their are many news, most of them are Forex oriented, and having too many alerts is not a good idea.
The good idea is maybe having a matrix, a table or something, which links the contract(s) traded with the news.

Do I need to add a using directive to use regex?

Yes:

using System.Text.RegularExpressions;
