FF Calendar Indicator for MT

In version 04 I had the problem of a divide by zero error if RefreshHour equals 0.

This is caused by the statement:
Inserted Code
if (FirstRun || (Minute() == RefreshMin && (Hour() % RefreshHour == 0)))

I changed this as follows:
Inserted Code
if (FirstRun || (Minute() == RefreshMin && ((Hour() + RefreshHour) % 4 == 0)))

This will still do a refresh every four hours at a random hour.

I also made some changes to display large minute values in days and hours as appropriate. I can post this if there is interest.

I'm attaching my changes as version 04a. I'm including a screenshot of the new display (should be the correct size):

I wonder if it is possible for ForexFactory to include also the "result" in the http://www.forexfactory.com/weekly_calendar.xml file.

Currently, it only contains, previous and estimates. It would be a big bonus if the actual is also included.

I just noticed this thread. The indicator looks great. I'll attach it to a chart today.

Thanks for your contribution and hard work.

Thank you,

I nominate this as the MVI ( Most Valuable indicator ) ever. It should be incorperated into Every EA. The profitability increases you get when you can filter the news is pheonominal.

Add the news results and the ability to relocate the data to different parts of the screen...and it'd be darn near perfect.

Even so, it's still very useful as is...thanks for this indy!

I;d like to point out that MT4 has a bug with time:

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

// Local timezone in hours, adjusting for daylight saving
double TimeZoneLocal()
{
int TZInfoArray[43];

switch(GetTimeZoneInformation(TZInfoArray))
{
case TIME_ZONE_ID_UNKNOWN: 
[b]Print("Error obtaining PC timezone from GetTimeZoneInformation in kernel32.dll. Returning 0");[/b]
return(0);

case TIME_ZONE_ID_STANDARD:
return(TZInfoArray[0]/(-60.0));

case TIME_ZONE_ID_DAYLIGHT:
return((TZInfoArray[0]+TZInfoArray[42])/(-60.0));

default:
Print("Unkown return value from GetTimeZoneInformation in kernel32.dll. Returning 0");
return(0);
}

To people who are located in TimeZones without DayLightSavings would get the highligted errors... You will need a better timekeeper than relying on the function call GetTimeZoneInformation(TZInfoArray).

Wow, amazing indicator, and, if it is indeed possible to retrieve the news result, and relay it in a split second, it would make even better.

Also, another feature that could be incorporated is, as soon as the result is obtained, then there could be an on-screen message in the chart displaying, "bullish" or "bearish", to keep us from spending precious seconds what the result possibly means. The reason why I don't say it should say "buy" or "sell", is because of course only the amount of deviation can determine that, and that is left to the user's discretion. But bullish/bearish would give a general indication. So for example, if and when the buy straddle order has been executed, and we have an on-screen display telling us, "bullish", then it will give us more confidence in the trade. If on the other hand, in the unlikely event our buy order is executed, yet we have at the same time an on-screen message displaying "bearish", then it could help us modify our exit strategy.

And of course there are numerous iterations on how one could apply the information.

This indicator opens up a bucket load of potential positive tweaks we can apply to our news trading.

I noticed a problem with refreshing of the news headlines. This may have to do with how often the currency pair updates. The indicator probably works best with a more active broker.

There also seems to be an occasional problem with the calculation of the times until/since shown in the headlines. Although, now I'm checking, it looks like something funny with the source data. It states that Tuesday at 5:00 am "Cleveland Fed President Pianalto Speaks". Seems kind of early, but what do I know... Does the FF calendar adjust to the user's local time?

derk and i talked about including the "actual" and decided against it. we have enough server load problems at release time, it could be harmful to also have thousands of MT platforms trying to grab the data as well. once we get our load under control (i know i know, we have been working on this problem for like 8 months, but im told its a very difficult situation to handle thousands of people refreshing the site at the same exact time) then we will evaluate including the actual in the xml. i do realize how big the possibilities are if we include the actual....it could make for some very slick indicators. so we will for sure address this when the time is right.
Relax and be happy.

I know squat about how your site is set up, so feel free to disregard what I'm about to say. Also... I get the feeling you're a pretty technical guy so don't think I'm talking down to you.

In general it's not serving a file that puts a sites performance in the toilet, it's the multiple DB calls that are required to generate a page. I'm betting if you had the data available in a lightweight xml file that less people would actually hammer against calendar.php.

telsa, im actually not all that technical. i do have a good understanding of web sites, but im not involved in the actual coding of this site. the only programming i do is in tradestation!

anyway, about your suggestion...i do see your point, but our problems are not with our db server (we solve db issues a few months ago). now the problem is with our web servers, which would be effected by xml grabs (although it is only slightly, it adds another variable to our equation and makes solving the overall problem more complex). i think we are in the process of adding load balancing so hopefully this clears up issue in the near future.
Relax and be happy.

This would be a good source of revnue for FF. charge a nominal subscription for server access to the FFCAL indicator. I would pay.

Yes, true. But it will be quite a lot more work for FF to get that added in. Namely, they would have to update the XML page right after every announcement. And what is worse, EVERYONE using it would have to update it, which would cause a horrible traffic spike.

So until we can give them a pretty god reason to put that much more effort into this....

They have been pretty kind & cooperative so far just to help me make this stable. I didn't get anything for it (except a lot of time spent, and some satisfaction) and they didn't get anything for it (except some notoriety and (unfortunately!) some high-traffic problems).

I have some ideas to discuss with them about the future and it's ability to give the current numbers, but don't expect anything for a while....

Theoretically, or are you seeing this from experience? Care to share which EA is producing such results? <wink>
