  Importing the attached ITF file will spare you from having to add variables.

  Sorry to be a pain Rob, I’ve hit a wall of sorts and it looks similar to the ITF you kindly provided back in the day (it too hits the same wall when plotting past the end of the old month and into a new month). Not posting this as a bump because I know you have your hands full more so to say there’s a bit of consistency here and it could be a simple one for your IP.

  I can plot lines half a dozen different ways (just about) and they work well w/in a given month, it’s only when you lean into the next months plot(s) that it falls over.

   

  I’ve even peeled out the last day of the month compute and it has no effect, so I’m guessing in there is the solution vs DayCount cfg perhaps.

   

  I know the dates are in numeric format and the ‘additional days’ are in integer form but I’ve not been able to push by what appears to be a hard limit (for me). Probably my lack of IP … !

   

  Below is a basic setup that manifests in the same way as the previously linked ITF. Just pushout the NumberOfDays variable past months end and it should break. The ITF linked a few pages back by you will also error. I feel like a bit of a dill not having picked up on it back in the day – would’ve prevented the need to revisit now but it’s now that as I’m putting together a housekeeping guide for family that I’ve come back to it. The historical ITF was extremely helpful in identifying where APAC and EU sessions influence, so many thanks for that input (was foundational for me with PRT).

  This post (and the following one) https://www.prorealcode.com/topic/need-help-with-date/#post-228150  might be of some help. Still it’s not exactly what you want.

  When you have a DATE, you must:

  • decompose it into Year, Month and Day
    .
  • calculate the last day of the Month (taking into account leap years) then add the desired number of days to the Day to get a NEW date
    .
  • pack the new YY, MM and DD into a date in the format YYYYMMDD.
    .

  I coded this snippet (tested against eXcel over a few centuries, roughly 200K days, to test leap years), to add days to any starting date (it can be easily adapted to subtractions):

  oldDate = 20210723 DD = oldDate MOD 100 //get DAY tempDate = (oldDate - DD) / 100 MM = tempDate MOD 100 //get MONTH YY = (tempDate - MM) / 100 //get YEAR tempDD = DD + 68 //add 68 days to compute the new date tempX = DD While 1 Do LastDay = 31 IF MM = 4 OR MM = 6 OR MM = 9 OR MM = 11 THEN LastDay = 30 ELSIF MM = 2 THEN LastDay = 28 IF YY MOD 4 = 0 THEN IF YY MOD 100 = 0 THEN IF YY MOD 400 = 0 THEN LastDay = 29 ENDIF ELSE LastDay = 29 ENDIF ENDIF ENDIF myRemainder = tempDD - LastDay IF myRemainder <= 0 THEN break ENDIF tempDD = tempDD - LastDay MM = MM + 1 IF MM > 12 THEN YY = YY + 1 MM = 1 ENDIF tempX = 0 Wend newDate = (YY * 10000) + (MM * 100) + tempDD //pack data into a new date

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36

  oldDate  = 20210723 DD       = oldDate MOD 100        //get DAY tempDate = (oldDate - DD) / 100 MM       = tempDate MOD 100       //get MONTH YY       = (tempDate - MM) / 100  //get YEAR tempDD   = DD + 68                //add 68 days to compute the new date tempX    = DD While 1 Do    LastDay = 31    IF MM = 4 OR MM = 6 OR MM = 9 OR MM = 11 THEN       LastDay = 30    ELSIF MM = 2 THEN       LastDay = 28       IF YY MOD 4 = 0 THEN          IF YY MOD 100 = 0 THEN             IF YY MOD 400 = 0 THEN                LastDay = 29             ENDIF          ELSE             LastDay = 29          ENDIF       ENDIF    ENDIF    myRemainder = tempDD - LastDay    IF myRemainder <= 0 THEN       break    ENDIF    tempDD = tempDD - LastDay    MM = MM + 1    IF MM > 12 THEN       YY = YY + 1       MM = 1    ENDIF    tempX = 0 Wend newDate = (YY * 10000) + (MM * 100) + tempDD  //pack data into a new date

  Many thanks Rob, your feedback is appreciated!

  I’ll have a look when I get a moment, probably closer to weekend, could be sooner, kind of eager to iron this one out or shelve it if need be, yet, I’m ever hopeful it can be sorted … 🙂

  Not bad for not having tested it Rob!

  Dropped it in a new indicator, defined a vline for ‘olddate’ and ‘newdate’ and it plotted both.

  I’ve always thought how weekend data is handled could be a problem, so I’ll POC against some manual calcs I have and see how close it marries.

  For now it looks very very good.

  The above works but as you can see it’s a replication of one process to add another single plot, which I’m happy to say works well, so there’s wins here.

  Is there another way to do this without replicating large chunks I wonder?

  Needing to ‘decompose’ the anchoring date each time is the crux here (thanks for emphasizing this Rob) , so we can ‘add’ too it and create the subsequent day counts, then run though the lastday/date loop to process the plot accordingly.

  I can tweak the lastday/date loop, to ‘bundle’ all the dates and years w/in the single loop (I think) but if I wanted 30 of them, wow, I’m hoping there’s an easier way.

  I’ll have a go at it again and see if I can compress a little, no doubt it’ll be a right mess but I’ll have a go. Any words of wisdom are welcomed and appreciated.

  Cheers,

  We can use arrays, but 2 separate indicators are needed, as the whole process need two nested loops, which returns an error:

  • MyDateCaller, is the first indicator which contains tha dates to be handled and the number of days to be added; it simply calls the second indicator passing it the two parameters (date + days)
  • DateSum, is the second indicator; it gets the two parameters, doing the required math, then returns the newDate to the caller.

  MyDateCaller

  // dates are not required to be in any order // $myDate[1] = 20210723 $myDate[2] = 20210823 $myDate[3] = 20200807 $myDate[4] = 20221023 $myDate[5] = 20230830 $myDate[6] = 0 //set to 0 if not needed $myDate[7] = 20170912 // Days2Add = 99 // FOR i = 1 TO lastset($myDate) oldDate = $myDate[i] newDate = CALL "DateSum"[oldDate,Days2Add] IF newDate > 0 THEN drawvline(datetobarindex(olddate))style(dottedline,2)coloured("red") drawvline(datetobarindex(newdate))style(dottedline,2)coloured("Green") ENDIF NEXT return

  only the indicator MyDateCaller needs to be added to your chart, the other simply needs to be present in the platform, among all other indicators.

  You may add as many dates as needed as array elements in the calling indicator.

  I don’t know what to say Rob. Thankyou. Honestly wow.

  I’ll give this a lookover, so I can do it a bit of justice.

  The current setup from, your workings, as I have tweaked it, adds days to a single date as well, as seen further on up above, my last effort, so will try that with myDateCaller, where I’ll have a series of numbers to be added to the date or dates. We count forward random day counts from a single date.

  So we’ll have say:

   

  $myDate[1]  = 20210723

  plus 3 days

  plus 12 days

  plus 20 days

  plus 27 days

  We’ll plot these days.

  It’s here where I became unglued if you will and had to create multiple DateSums equiv. but here you’re calling it to calc out.

  Yes, I think this will do nicely on that front but will I be able to handle the multiple days as above, 3, 12, 20 etc or will I need to call the days as well.

  I have a go and let you know how it goes, fingers crossed … 🙂

   

  Many thanks again.

  This was the setup, pre your latest reply Rob, you can see how the wheels been re-invented a few times here!

  I think we’re headed in the right direction (your last post) and appreciate your time.

  Replace the calling indicator MyDateCaller  with this one:

  $myDate[1] = 20210723 $myDate[2] = 20210823 $myDate[3] = 20200807 $myDate[4] = 20221023 $myDate[5] = 20230830 $myDate[6] = 20230226 $myDate[7] = 20170912 $add2date[1] = 99 $add2date[2] = 315 $add2date[3] = 18 $add2date[4] = 65 $add2date[5] = 30 $add2date[6] = 544 $add2date[7] = 210 FOR i = 1 TO lastset($myDate) oldDate = $myDate[i] Days2Add = $add2date[i] newDate = CALL "DateSum"[oldDate,Days2Add] IF newDate > 0 THEN drawvline(datetobarindex(olddate))style(dottedline,2)coloured("red") drawvline(datetobarindex(newdate))style(dottedline,2)coloured("Green") ENDIF NEXT return

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

  $myDate[1]    = 20210723 $myDate[2]    = 20210823 $myDate[3]    = 20200807 $myDate[4]    = 20221023 $myDate[5]    = 20230830 $myDate[6]    = 20230226 $myDate[7]    = 20170912   $add2date[1]  = 99 $add2date[2]  = 315 $add2date[3]  = 18 $add2date[4]  = 65 $add2date[5]  = 30 $add2date[6]  = 544 $add2date[7]  = 210   FOR i = 1 TO lastset($myDate)    oldDate  = $myDate[i]    Days2Add = $add2date[i]    newDate = CALL "DateSum"[oldDate,Days2Add]    IF newDate > 0 THEN       drawvline(datetobarindex(olddate))style(dottedline,2)coloured("red")       drawvline(datetobarindex(newdate))style(dottedline,2)coloured("Green")    ENDIF NEXT return

  I added an array also for the number of days to add to a date. Element 1 of the array $add2date will be added to element 1 of the array $myDate and so on…

  Thanks Rob, I’ll give this a go and see how it works.

  I was hopeful that we could cfg dates and added nbrs  via GUI, which is were you implied earlier on that this will get us to a working solution maybe minus the full GUI capability but everything’s a measure in compromise, so if I can get a workable solution it probably doesn’t matter where I plug the dates into and if the # are kind of static we can housekeep those and  we can then focus on ‘ beautification of dates ‘ once I see how it’ll impact workflows but from we are at the moment there’s been huge wins imo, so thanks again.
