Pips4Life, thank you for sharing this and for all your hard work.

I used the revised utility file on build 600+ to compile Hanover's "Display Info Indicator" but found that PlotLabel selectively output only some rows, leaving space for the rest of the rows (as if the text colour was the same as the background). Image of output and related query in another thread here (post7988277)

If anyone has encountered the same problem, and found a workaround, it would be great if you can share some pointers.

Thanks,
Nidagr

UPDATE (Aug 11, 2014): Pips4life has very generously updated these functions so that they will work correctly in MT4 builds 600 or later. You can download the new versions of the files, and also read his notes and disclaimers, here. As far as I know, the functions should continue to work exactly as they did before. NOTE (Jan 31, 2014): Any indicators or EAs that I have contributed to this thread will probably no longer work in the latest MT4 build that is (if I understand...
Hi Hanover, I´m from Brazil and I want talk to you.
Can you give me your e-mail?
Thanks

Announcing: New "v3" updates (b600+) to hanover's utility functions in my thread:
Modified, useful MQ4 utilities, indicators, and related tips (pips4life) (here)

2017-May-06: v3 released, of Hanover's utility functions (include files).

New files are posted, with new names as follows:

  1. For >= b600 (currently MT4 is at b1065):

    1. hanover --- function header b600 (np).mqh
    2. hanover --- extensible functions b600 (np).mqh

  2. For b509: (Mostly same as above, but with slight changes back to "509". It's easier to maintain both if their almost identical)

    1. hanover --- function header b509 (np).mqh
    2. hanover --- extensible functions b509 (np).mqh

These are based on the 2016-04-29 files posted by hanover (in post#1 of this thread).

These v3 files have resolved a significant bug (in v2, my first b600 version), that didn't work with some of hanover's indicators. This one can work with Display Info All Pairs, which had problems with the earlier version. (NOTE: The "Display Info All Pairs.mq4" must ALSO be updated to b600!! I've posted my b600 variation in the other thread here ).

Hi,

I need to put date in TextProperties for DLB.

I want it to be like: n D, Y

How should I place this in the common format? Am having troubles with commas.


Plus, is it possible to have Box height 1st, then week, then HL in the output?

That's because the commas are used as field separators in this case. However, most fonts allow the use of Alt-130 as a substitute for a comma, i.e. hold down the Alt key while you type 0130
e.g. set TextProperties to something like
Verdana,9,Silver,4,HL,n D‚ Y,T3.5'; ',0
where the highlighted character is Alt-130

This can be achieved only by changing the program code.

I was wondering, is there a way to see if the date is the third Monday of January or not? We know Americans will have a day off and it would be a handy tool to mark the date on the monitor for that particular day. I already have a trader assistant, would be nice if I add this functionality to it.

Here is a sample MQL4 function that will return the day of the 3rd Monday; if you provide the MQ4 file for your trader assistant, perhaps some programmer would be kind enough to modify it.
Inserted Code
  for (int year=2000; year<2031; year++)
    Print("Third Monday in " , year , " is January ", ThirdMondayInJanuary(year));
    
//+------------------------------------------------------------------+
int ThirdMondayInJanuary(int yyyy=0)  {
//+------------------------------------------------------------------+
// Given the year, the function returns day (15 to 21) that was the third Monday in January of that year
  if (yyyy==0)   yyyy =TimeYear(TimeCurrent());
  MqlDateTime mdt;
  mdt.year=yyyy;
  mdt.mon=1;      // January
  for (mdt.day=15; mdt.day<=21; mdt.day++)  {
    TimeToStruct(StructToTime(mdt),mdt);
    if (mdt.day_of_week == 1)   // Monday
      return(mdt.day);
  }
  return(0);
}

The above fragment produces the following output:
