[quote=hanover;4107525]HJ,

First, thanks for the detailed explanation and screenshot...]


Hi David,

Thanks for the quick and detailed response. Following your instructions I have been able to download the missing data and the indicator is working great again.http://cdn.forexfactory.com/images/icons/icon14.gif

I am guessing that I might have had an inconsistency between the "starting from what date" field & the "number of weeks worth of data to load" field in FFcal.EXE.

I do have one more question...

My understanding from reading your documentation is:
FFcal.EXE calls WGET.EXE which updates the Clarion database and then reads from that database to create news.csv and @[email protected].
and that Recent News indicator only reads data from news.csv

Lets say I use two different preset files for indicators on different charts, one looking back 5 weeks and another looking back 12 months. What determines the amount of data that is written into news.csv? Does it depend on settings in FFcal.EXE or are the preset files also taken into consideration?

Best Regards,

John.

That is 100% correct.

The process is as follows:

1. The settings in the top panel of FFcal.EXE's options screen determine which news events get downloaded from FF calendar, via WGET.EXE. These are downloaded into the (growing) Clarion database. You can always press Esc and then F9 to see what's in the database.

2. The settings in the large central panel of FFcal.EXE's option screen determine which entries in the Clarion database get output to the news.csv file. These settings may be used to filter news events by date range, impact, currency, description, etc. You can click the 'Preview' button to see which events will be output to news.csv. However, it is probably simpler to output everything, and apply filters at step 3 (below) instead.

When you click 'OK' in FFcal.EXE, both steps 1 and 2 are performed. Additionally, the @[email protected] file is rebuilt from ALL events in the Clarion database (filters are ignored), along with other options (additional exports, effect analysis report, NCI, etc).

3. The Recent News indicator reads the news.csv file every time the indy is refreshed (see post #25 for info on manual vs auto refresh). The filter settings in your parameter file (PlotTheseImpacts, PlotTheseCurrencies, RelevantCcyChartsOnly, etc) further restrict the events that will be plotted, alerted and/or exported.

NOTE: if you run the Download News script with AutoplayMode = TRUE, FFcal.EXE settings are overwritten to cause a download of the current week's (Sunday to Saturday) news events only, and only the last 35 days' worth of news events are output to news.csv. To override this, either (i) set AutoplayMode = FALSE (which pauses at FFcal.EXE's option screen, allowing you to type your own settings), or (ii) run FFcal.EXE from Windows yourself (or create an icon on your desktop).

The links in this post will direct you to more detailed info on how to use FFcal.EXE's functions.

No. All seems to be working fine. Though will probably have to refer to instructions in order to remember how to download next week. It was strange the all events in ver. 1.37 stopped last Tuesday, and gave me a scare, but new is working good now.

Is this a known problem and can something be done?

I am sorry, I run Win XP only, hence I'm not able to troubleshoot on Win 7.

It might be that Win 7 locks you out of certain folders (probably c:/Program Files), unless you're signed on as system administrator. Hence you could try signing on as system administrator, and/or re-installing MT4 (and then the files in post #1) somewhere other than under c:/Program Files.

Maybe if your describe your problem in more detail (i.e. what specific error message you're getting, and at what stage in the process - or even better, a screenshot of the error), somebody else might be able to help.

OK, now I've got a problem. It turns out that last week i was running Plot_News instead of the new Recent_News on my chart, and everything worked fine. This wouldn't work this week for some reason and figured out it was necessary to use Recent_News. But it won't display the right time.

Have tried running the script Calc Timeshift but now this says - after giving all the permissions - that my time is GMT-4, though the first time I ran it today it was GMT-5 which is my time and don't think this has to do with Daylight Savings. In any case after downloading from FF again, this doesn't seem to have any effect on what's displayed on the chart.

The setting in the indicator on the chart are correct. Will try installing the whole thing again, 'cause when I downloaded from FF last week it was by running the script Download News, but this week that wouldn't work so had to go to Files folder and open FF_cal the old way. Lordy, this is complicated.

OK, now I got it to display right by changing the settings in the indicator on the chart to the way Calc Timeshift set them in the first place when it said GMT-5 this morning, but this seems wrong to me. My FF is set for GMT-5 but the indicator in the chart says O! Oh well, in any case it works.

Bruce, it's not too hard to check this. When you run Calc Timeshifts, it shows New York time (which is also the FF calendar source time), GMT, MT4 time and your Local time at the top.

You can check that New York time is correct by comparing it to this.

You can similarly check GMT here.

You can get MT4 time from the top of the Market Watch window (provided that the market is currently open). Press Ctrl-M to obtain Market Watch. Then see the screenshot below.

You can check Local time against your computer's clock (at the right hand end of the systray).

If all of these are correct, then the calculated values should be correct also. You can verify this by calculating the differences yourself.

Can I download the file manually and copy it over to MT4?
If so, where can I find the file?

The files are arranged in the ZIP archive in the same folders that they need to be downloaded/copied into.

For example, the file FFcal.EXE exists in ZIP/experts/files
hence it should be copied to [your MT4 folder]/experts/files

Same for the other files.

OK.
And the FF news file? Do you have an URL?
Can I just download it and copy it without any changes?

The Download News script calls an external app FFcal.EXE which downloads news events from the URL http://www.forexfactory.com/calendar.php into a file ..../experts/files/news.csv

The Recent News indy then reads this file, and plots the news events on the MT4 chart.

For more detailed info, please read the Word doc in the ZIP.

However the @effdet is still capturing the FF time of 7am. Seems like it's independent of whatever value I enter.
Not sure if you're still around. Anyway, I spent some time over the weekend investigating this. I was able to reproduce the same error, but I'm in the embarrassing situation of not knowing how to fix it.

I'd post the relevant parts of the source code, but it's written in Clarion, and I doubt that any Clarion programmers read this forum.

Hi hanover,
and thanks for this very useful application.

I just managed to use it succesfully and I am looking at the @backup@ file it created.

It seems to have all the events starting from 2007 as expected, but when I look at the end of the file, it has events for 2010-11-12 then 2010-11-11, nov. 10, nov. 9, nov. 8 and even some for nov. 7...

then the entry right before is dated 2010-08-20

so my question would be : how come am I missing the whole range 2010-08-21 to 2010-11-06...and then maybe some more? I did not validate through the entire file.

Thank you very much for any reply

PS. Also : is it possible to generate the @backup@ file in GMT time (+0)?

The reason is that v 3.03 was uploaded to post #1 circa 2010-08-20, but you've only been adding news events since 2010-11-06, hence the gap.

Anyway, here is the solution: download the files in the attached ZIP to your ..../experts/files folder, overwriting existing files of the same names. These files contain all news events from FF calendar between 2007-01-01 and 2010-11-06. These are timestamped with New York EST (which is FF calendar's timezone).

I assume that you'll be importing the data from @[email protected] to Excel? If so, you can convert the timestamps to GMT easily enough. Simply add 4 hours whenever New York is on daylight saving, and 5 hours when it's not. Suppose you have the dates in column A and times in column B of your XLS. Then create a new column with a formula like =A1+B1+X/24, where X = 4 or 5 (hours).

New York observed daylight saving between these dates:
2007-03-11 and 2007-11-04
2008-03-09 and 2008-11-02
2009-03-08 and 2009-11-01
2010-03-14 and 2009-11-07


[EDIT] Alternatively, the Convert to GMT.MQ4 script (which I've just written hastily, please check the result carefully) should convert the timestamps in the @[email protected] file to GMT, and output the result to a file named @[email protected], based on the approach I described above. Download it into your ...../experts/scripts folder, restart MT4, and then run it.

Thank you very much for your insightful reply.

I was indeed worried with DST when converting times to GMT but I feel confident now that you confirmed the correct way to do it.

Is there no need to worry with European/American/South hemisphere DST as they all start and end on different dates?
I would assume AUD and NZD news follow southern hemisphere DST rules
then GBP, EUR, CHF, etc. follow European DST rules
USD, CAD, etc. follow American DST rules
and so on

thanks again and best regards
p.s. sorry for my bad english

Every country has its own DST rules. Moreover, countries that are large in area may have different DST rules for different areas within the country. More info here.

This is the best News Indicator by far: neat, clear, uncluttered.

The only feature I can't seem to operate is when updating for the new week:
"Open MT4's Navigator (press Ctrl-N), and drag the Download News script onto any MT4 chart"
When I do this nothing updates. I have to go into experts/files and run ffcal.EXE directly by double clicking on it.
I thought running the Download News script from within the MT 4 Navigator was meant to do this?

Am I missing something here?

Othrwise another superb indicator, Hanover.
