dailyFX news indicator (closed)
Nikolay.Gekht · Sun Apr 11, 2010 7:58 pm
Note: The post is closed. Please read this topic viewtopic.php?f=17&t=1972 about new version of the indicator
The indicator shows dailyfx calendar (http://www.dailyfx.com/calendar/) event headlines on the chart.
The indicator takes only those events which are related to the currencies of the currently selected instrument.
The indicator shows a number of news for the bar. The green number above the bar is a positive news, a red number below the bar is negative news. If you move a mouse cursor over the number, the toolip with headlines will be shown.
The indicator also loads and shows the news for 300 further bars.
Notes: 1) Only last 90 days events are loaded. 2) I do not recommend to use the indicator on 1-day and above chart. The news loading is synchronous and can “freeze” the marketscope for up to one minute, especially in case the internet connection is not pretty good.
Update: Aug, 02 2010. The new version of the dailyfx has been released.
a) you can choose whether you want to see all currencies or only currencies which the current currency pair consists of. b) you can choose whether you want to see all importances, or Medium + High or High only news. c) Actual and Forecast values are also shown in the tooltip.
Download the indicator:

Excellent work… as usual. You have been busy lately with all these updates; just wanted to pop in and say, thank very-very much!
I wish there was tip/donate button on this website so we could actually get a little extra $ in your hands.

Thank you very much for your generous proposal. Our team is really happy to make trader’s life easier. Hopefully, money earned on the development and support of the Trading Station, Marketscope applications, the reporting system and Order2Go API (yeah, we are those “bastards” who developed all these client-related things) is enough to support this site. The expression of your satisfaction with these products (and, probably, not only at this site) is the most valuable result of our work. So, if you like it - just do not hesitate to tell about it. It will be the best support of our work.

Fantastic! I just want to say that I totally agree with Patick Nikolay. You should know that we do not take this for granted. I now have indicators for Marketscope that I for not too long ago could only dream about. By the way, thank you for the Value Charts indicator. I did not know about it at all until you posted it. I have noticed that besides of the basics the Value Charts indicator has some not immediately obvious properties that is very interesting and worth looking into I think.
Thank you very much

Hi Guys
I’m a relatively new trader and have only just found this board and custom indicator factility. I have installed the News Indicator, a simple but really useful tool. Install was simple but I notice that it local time does not seem to work or perhaps I’m missing something.
I’m in the UK on GMT +1. The news is not aligned to the correct candle and is 5 hours out e.g. 08:30 (GMT) news release aligns with the 13:30 candle.
Any ideas?
thanks

Thank for the report. It looks like the timezone-based request on dailyFX site is broken. It returns the time in GMT even if the EST requested. I apologize for the inconvenience. Hopefully, now the Marketscope can convert data b/w timezone, so, I’ll change the data requesting to GMT and will use the Marketscope’s function to convert into EST (to find the proper candle) and to displayed data (to show the labels more convenient).
…. and already updated.

This in our plans…
I apologize that preparing the new release takes so much my time, so I’m just not able to care about fxcodebase as before. I hope that I’ll finish and will be completely back in a couple of week.

Update: Aug, 02 2010. The new version of the dailyfx has been released. Unfortunately, the URL format for getting calendar data has been changed, so you need to update the indicator in order to get it working again. Also, a) you can choose whether you want to see all currencies or only currencies which the current currency pair consists of. b) you can choose whether you want to see all importances, or Medium + High or High only news. c) Actual and Forecast values are also shown in the tooltip.
Please download the updated indicator from the top post of this topic (viewtopic.php?f=17&t=603)

Exelent work, but the indicator do not display the news in correct time, the USD Federal Open Market Committee Rate Decision (AUG 10) is displayed in other time. if i can fix it, tell me how.
Re: dailyFX news indicator [updated Aug, 02]
Nikolay.Gekht · Tue Aug 10, 2010 11:15 am
Hm… dailyfx displays it at 18:15UTC on the site, but, when csv calendar is requested, it sends it at 14:15. I’ll ask dailyfx team why. There is no problem in indicator, rather the problem in the data sent by dailyfx. Anyway, thank for the reporting. This will help dailyfx team to improve their new version of the site.

And now they have changed format of the file. They gotta make us all crazy. I’m handling this, give me a couple of hours, please.
upd: It looked much easier than I expected. They just changed the time format. Fixed. Please reinstall the indicator.
