Chart TIMEFRAME detection in an indicator?

  Hi

  I have two questions related to timeframes.

  • Is it possible for an indicator to detect what timeframe the chart is when it’s applied? I’ve looked at https://www.prorealcode.com/documentation/timeframe/ and also https://www.prorealcode.com/prorealtime-indicators/higher-timeframe-rsi/ but not sure if it can be done. I work entirely on charts of different minute timeframes.
  • With the TIMEFRAME statement, can you specify minutes as opposed to hourly, daily etc?

  Thanks again.

  Rob

  TIMEFRAME statement is only available for ProScreener program. It should be used also for ProOrder, but in a future update.

  About code to detect which timeframe is the current chart, you can use this one:

  once NbBar = 1 //if BarIndex < NbBar+2 then MyDay=openday dayminutes = 1440*(MyDay-MyDay[1]) MyHour=openhour hourminutes = 60*(MyHour-MyHour[1]) MyMin=openminute barminutes = MyMin - MyMin[1] + hourminutes + dayminutes barminutes=abs(barminutes) Mybarminutes = lowest[NbBar](barminutes)[1] //endif return Mybarminutes as "Timeframe"

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

  once NbBar = 1   //if BarIndex < NbBar+2 then MyDay=openday dayminutes = 1440*(MyDay-MyDay[1]) MyHour=openhour hourminutes = 60*(MyHour-MyHour[1]) MyMin=openminute barminutes = MyMin - MyMin[1] + hourminutes + dayminutes barminutes=abs(barminutes) Mybarminutes = lowest[NbBar](barminutes)[1] //endif   return Mybarminutes as "Timeframe"

  Hi Nicolas,

  Thanks for this but I’m experiencing a problem with it. Is there a workaround you can think of? I have tried calling it using CALL but I still get the error when trying to create the Donchain channel.

  Thanks again, Rob

  once NbBar = 1 //if BarIndex < NbBar+2 then MyDay=openday dayminutes = 1440*(MyDay-MyDay[1]) MyHour=openhour hourminutes = 60*(MyHour-MyHour[1]) MyMin=openminute barminutes = MyMin - MyMin[1] + hourminutes + dayminutes barminutes=abs(barminutes) Mybarminutes = lowest[NbBar](barminutes)[1] //endif lower = lowest[Mybarminutes](low) upper = highest[Mybarminutes](high) middle = (upper + lower) / 2 return lower as "lower", upper as "upper", middle as "middle"

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

  once NbBar = 1 //if BarIndex < NbBar+2 then MyDay=openday dayminutes = 1440*(MyDay-MyDay[1]) MyHour=openhour hourminutes = 60*(MyHour-MyHour[1]) MyMin=openminute barminutes = MyMin - MyMin[1] + hourminutes + dayminutes barminutes=abs(barminutes) Mybarminutes = lowest[NbBar](barminutes)[1] //endif   lower = lowest[Mybarminutes](low) upper = highest[Mybarminutes](high) middle = (upper + lower) / 2   return lower as "lower", upper as "upper", middle as "middle"

  Sorry but I don’t understand what you are trying to do with this code?

  Example: in an 1 hour timeframe, the code I gave you will return “60”. “240” in a 4 hours timeframe, etc.

  I agree it’s a bit odd so I’ll try and explain.

  If I add this indicator to a twenty minute chart, I was hoping it would detect that it’s a twenty minute chart and simply create a 20 period Donchian channel rather than having to set the period manually.

  Try adding it and you’ll see the problem.

  This code should work ok:

  once NbBar = 2 MyDay=openday dayminutes = 1440*(MyDay-MyDay[1]) MyHour=openhour hourminutes = 60*(MyHour-MyHour[1]) MyMin=openminute barminutes = MyMin - MyMin[1] + hourminutes + dayminutes barminutes=abs(barminutes) Mybarminutes = lowest[max(1,NbBar)](barminutes)[1] if barindex>MyBarminutes then lower = lowest[Mybarminutes](low) upper = highest[Mybarminutes](high) middle = (upper + lower) / 2 endif return lower as "lower", upper as "upper", middle as "middle", mybarminutes

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

  once NbBar = 2 MyDay=openday dayminutes = 1440*(MyDay-MyDay[1]) MyHour=openhour hourminutes = 60*(MyHour-MyHour[1]) MyMin=openminute barminutes = MyMin - MyMin[1] + hourminutes + dayminutes barminutes=abs(barminutes) Mybarminutes = lowest[max(1,NbBar)](barminutes)[1]   if barindex>MyBarminutes then lower = lowest[Mybarminutes](low) upper = highest[Mybarminutes](high) middle = (upper + lower) / 2 endif   return lower as "lower", upper as "upper", middle as "middle", mybarminutes

  Still don’t have understood the relationship between how much minutes in a single bar and the period of the donchian channel ❓

  Hi Nicolas (I write in English since this topic belongs to the englishspeaking forum)

  Wondering how I could detect the timeframe to change automatically some parameters in an indicator, I began to test the code you posted on this page (I just made a copy/paste of the above code, without changing anything).

  But I get some very strange results, rather regularly(see the attached file) :for example, for the CAC40 index in 1 hr, I get 60 min (normally), but with a very regular periodicity, on the same graph, the result becomes 960, or 3840, or even 6720 and 37920 (see the attached file). There must be some bug by there !…

  Could you give a look ? Thanks in advance.

  Patrick

  Hi Patrick

  I came across an issue with this code and managed to mess it about to get it to be constant. However, I can’t see your code so I don’t know if it will help you.

  Cheers

  Rob

  PS my changes make little sense but it worked for me, I was getting blips.

  // Some hacky code to work out what the chart timeframe is in minutes up to 1597 MyDay=OpenDay DayMinutes = 1440*(MyDay-MyDay[1]) MyHour=OpenHour HourMinutes = 60*(MyHour-MyHour[1]) MyMin=OpenMinute BarMinutes = MyMin - MyMin[1] + HourMinutes + DayMinutes BarMinutes = ABS(BarMinutes) IF BarMinutes = 5 THEN ChartTimeframe = 5 ELSIF BarMinutes = 15 THEN ChartTimeframe = 15 ELSIF BarMinutes = 30 THEN ChartTimeframe = 30 ELSIF BarMinutes = 60 THEN ChartTimeframe = 60 ENDIF RETURN ChartTimeframe as "Chart timeframe"

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

  // Some hacky code to work out what the chart timeframe is in minutes up to 1597   MyDay=OpenDay DayMinutes = 1440*(MyDay-MyDay[1]) MyHour=OpenHour HourMinutes = 60*(MyHour-MyHour[1]) MyMin=OpenMinute BarMinutes = MyMin - MyMin[1] + HourMinutes + DayMinutes BarMinutes = ABS(BarMinutes)   IF BarMinutes = 5 THEN ChartTimeframe = 5 ELSIF BarMinutes = 15 THEN ChartTimeframe = 15 ELSIF BarMinutes = 30 THEN ChartTimeframe = 30 ELSIF BarMinutes = 60 THEN ChartTimeframe = 60 ENDIF   RETURN ChartTimeframe as "Chart timeframe"
