News Trading Script?

Is anyone aware of any news trading scripts here that would have major news days and times preprogrammed?

Most news EAs I've seen require manual insertion of future news times which makes impossible backtesting.

I was thinking of a script or code that would have the major days and times precoded. Then devise strategies around those times with new or existing EAs.

Anyone aware of existing code to start with?

I wouldn't mind manually inserting all major news days and times for the month in advance to begin with, but ideally want something that takes the news days and times into code. Which brings up the question:

Monday August 26th at XX:XX is easy to code in advance but how would one code the 4th Monday of each month as a predefined event? Any ideas for logic or code to tackle this?

There's no need to code a "calendar" with dates and times to avoid trading. Just a news events filter linked to the FF calendar.

I didn't make myself clear. I want to code a news calendar to trade around it (automated). Not to avoid trading around it.

All regular news is regulated at a certain time on a certain day of a particular month. Usually within a numbered week. Want to create code that isolates these dates and times for future days and historical days.

What you want to do is possible, but probably not easy. You will have to take your broker's time zone into account, so it might break if used on another broker.

MQL has some handy date functions you should familiarize yourself with like DayofWeek() and Hour(). So to avoid trading the NFP, code something like
if (DayofWeek() == 5 && Day() <8) // first Friday of month
{
// do something
}
else
{
// do something
}

For the 4th Monday in the month, I would think that you would check if today is Monday and then check the date.
If the date is >=1 && <8 it is the 1st Monday.
if >=8 && smaller than 15 it's the 2nd Monday
if >=15 && <22 3rd Monday
>=22 && <29 4th Monday

Of course, this would be done with loops to save typing.

My answer was exactly fine for either filter or trade the news events. Once the EA is linked to the FF calendar, you do what ever you want of the info received.

I've thrown this together and you may be able to use or adapt some of it to what you want.
Obviously, if you used this sort of thing in strategy tester, the time would only be accurate to the smallest timeframe used.

The ReturnDay(int count, string dow, datetime start) function here will do this.

For example, to obtain the MT4 datetime value of the 4th Monday in Dec 2013 (i.e. the 4th Monday after Dec 1, 2013):
ReturnDay(4,"Mon",StrToTime("2013.12.01"))

For example, to return the 4th Monday in each month in 2013:

for (int i=1; i<=12; i++)
Print(DateToStr(ReturnDay(4,"Mon",StrToTime("2013."+NumberToStr(i,"Z2")+".01")),"w D n Y H:I:S"));
