coding help about buy and sell on certain days of the month

  Hi there,

  I am a new ProRealTime user and just working my way through the programming manual in order to get to grips with the programming language!

  It would be ever so helpful if someone could tell me the correct code for the following – it would help with my understanding of how the specific monthly date element of coding works:

  Buy on the last 2 trading days of the month and sell at the close on the 3rd trading day of the month

   

  If someone would be kind enough to tell me the code for the above lines, it would help me as I work through the ProRealTime coding manual.

  Many thanks for your help!

  Rob

  I wrote functions to know if we are on the last day of month for someone else, here are the codes:

  This indicator will tell you the number of the last traded day of the current month (save it as an indicator named “#lastdayofmonth”):

  RETURN the last trading day of the month

  //bisextil year or not? If Year Mod 4 = 0 And (Year Mod 100 <> 0 Or Year Mod 400 = 0) Then IsBisextil = 1 Else IsBisextil = 0 EndIf //days quantity per month if IsBisextil then feb=29 else feb=28 endif //get the last day of the current month if month=1 or month=3 or month=5 or month=7 or month=10 or month=12 then lastdayofmonth = call "#get_lastdayofmonth"[year,month,31] elsif month=4 or month=6 or month=8 or month=9 or month=11 then lastdayofmonth = call "#get_lastdayofmonth"[year,month,30] elsif month=2 then lastdayofmonth = call "#get_lastdayofmonth"[year,month,feb] endif return lastdayofmonth

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

  //bisextil year or not? If Year Mod 4 = 0 And (Year Mod 100 <> 0 Or Year Mod 400 = 0) Then IsBisextil = 1 Else IsBisextil = 0 EndIf   //days quantity per month if IsBisextil then feb=29 else feb=28 endif   //get the last day of the current month if month=1 or month=3 or month=5 or month=7 or month=10 or month=12 then lastdayofmonth = call "#get_lastdayofmonth"[year,month,31] elsif month=4 or month=6 or month=8 or month=9 or month=11 then lastdayofmonth = call "#get_lastdayofmonth"[year,month,30] elsif month=2 then lastdayofmonth = call "#get_lastdayofmonth"[year,month,feb] endif   return lastdayofmonth

  This code above need this other function (saved as an indicator named “#get_lastdayofmonth”).

  #get_lastdayofmonth

  //what is the day of week? if myMonth >= 3 then D = (((23*myMonth)/9) + myDay + 4 + myYear + (myYear/4) - (myYear/100) + (myYear/400) - 2) mod 7 else z = myYear - 1 D = (((23*myMonth)/9) + myDay + 4 + myYear + (z/4) - (z/100) + (z/400) ) mod 7 endif lastday=myDay if D=6 then lastday=myDay-1 elsif D=0 then lastday=myDay-2 endif return lastday

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

  //what is the day of week? if myMonth >= 3 then D = (((23*myMonth)/9) + myDay + 4 + myYear + (myYear/4) - (myYear/100) + (myYear/400) - 2) mod 7 else z = myYear - 1 D = (((23*myMonth)/9) + myDay + 4 + myYear + (z/4) - (z/100) + (z/400) ) mod 7 endif   lastday=myDay if D=6 then lastday=myDay-1 elsif D=0 then lastday=myDay-2 endif   return lastday

  So in your strategy, you’ll have to code something like:

  lastdayofmonth = CALL "#lastdayofmonth" //buy the last day of the month if day=lastdayofmonth then buy 1 contract at market endif //sell at 3rd day of the next month if longonmarket and day>=3 then sell at market endif

  1 2 3 4 5 6 7 8 9 10 11

  lastdayofmonth = CALL "#lastdayofmonth"   //buy the last day of the month if day=lastdayofmonth then buy 1 contract at market endif   //sell at 3rd day of the next month if longonmarket and day>=3 then sell at market endif

  Hi Nicholas.

  I’m interested in buying or selling at start or end of the month but have no idea how to code it right except manually enter dates. Any help possible?

  P.s. tried this code but can’t get to work 🙁

  I think I worked it out right after posting. All good. Lets see how it rolls.

  If, like me, you’d forgotten how to pass parameters to indicators, this is very helpful: https://www.prorealcode.com/blog/video-tutorials/adding-dynamic-parameters-to-your-indicators-prorealtime/
