FFCalendar - show upcoming news as vLines in chart?

Hi,
It does not work out for me to tweak the code of Derk Wehlers FFCal to show the vertical chart-Lines (which show the news event at time of arrival and in history) to appear BEFORE the event happens (say, appearing from the right side of the chart).

It must be somewhere around lines 584 & 753 & 828 where one could tweak it (I think)

thought I just would have to set
Inserted Code
if (TheTime > Time[0])
instead of
Inserted Code
if (TheTime < Time[0])
, in line 856,
but that did not work.

Did anybody tweak it already, or is capable of? That would be of big help for me.


another thing which disturbs me, and I don't know how to fix it:
quite often a black vertical line appears in the chart, and it's created thru FFCal, but has no relevance, must be a bug. I could not fix it..

Anybody?
Thx Lowen

Don't know if this helps you, but there's an indicator attached to this post that will display news events as vertical lines on MT4 charts. Sorry, I don't use this indicator, so I can't comment further.

Thanks hanover. I should have read your thread more thoroughly
I will check this out. I just dragged it to my chart and it looks like what I wanted - just have to check if the displayed dailyfx newsevents are ok for me..

thx again

btw David,
I guess it's not so easy to set your own FFCal indicator to just display vert lines w/o all the other stuff?


If anybody has a solution for my initial question, I'd still be glad about it.



I have some problems with news.mq4.
Summertime or distance to GMT does not work correct, and the news announcements differ somewhat from the FFCalendar ones (also I wonder who declares if sth. has low or high impact, eg. Manufacturing Production m/m GBP is LOW on dailyfx and HIGH on FF)

This is BK's version.
It draws vertical lines like you described.
I don't know if this is indeed what you wanted though.

You might want to contact him for your specific features in case this isn't what you wanted.

When I first wrote Plot_News, I did consider using vertical lines. But there is the problem when you get multiple events occurring at the same time - only one can be plotted. Also, I find the vertical text hard to read, and it clutters up my chart (for better or worse, I tend to use lots of indicators and S/R lines). Anyway, just my personal view.

Sorry, as I said, I don't use this indicator.

yeah I understand what u mean with the cluttering.
I wanna use lines as it reminds me more intensive that there's a news event coming

nevermind.
I found a way to adapt Derk's script. in a way.
It now does what I want.
Somehow the vLines don't involve the time distance from broker to GMT. Not sure what happened..

thanks a lot,
I'll check it.


Btw: concerning programming mq4.
Can anybody tell me how I get the timedifference (in minutes) between current MT4-Broker and GTM?
In the FFCalendar I can find this code, but as I'm not a programmer I did not find out how to easily create a var that holds that info:

Inserted Code
#import "kernel32.dll"
int  GetTimeZoneInformation(int& TZInfoArray[]);
#import

#define TIME_ZONE_ID_UNKNOWN   0
#define TIME_ZONE_ID_STANDARD  1
#define TIME_ZONE_ID_DAYLIGHT  2

int TZInfoArray[43];

datetime TimeGMT() 
{
int DST = GetTimeZoneInformation(TZInfoArray);
if (DST == 1)
DST = 3600;
else 
DST = 0;

return( TimeLocal() + DST + (TZInfoArray[0] + TZInfoArray[42]) * 60 );
}

EDIT: Got it now (in a way). CurTime() seems to return Brokers Server time, and I can now substract GMTtime from that for difference (or other way round if Broker is <GMT)
