Question on Highest[BarIndex – lastWeekBarIndex](Price)

  Hi Nicholas,
  Could you please advise what’s different for X by using DailyHigh and High in “Highest[BarIndex – lastWeekBarIndex](X)”?
  I observed some weeks having different result but I couldn’t explain why?

  Which parameter is correct? I tried it on 4hours time frame.

   

  // calculate daily high/low dailyHigh = DHigh(1) dailyLow = DLow(1) // calculate weekly high/low If DayOfWeek < DayOfWeek[1] then weeklyHigh = Highest[BarIndex - lastWeekBarIndex](dailyHigh) // weeklyHigh = Highest[BarIndex - lastWeekBarIndex](High) lastWeekBarIndex = BarIndex ENDIF

  1 2 3 4 5 6 7 8 9 10

  // calculate daily high/low dailyHigh = DHigh(1) dailyLow = DLow(1)   // calculate weekly high/low If DayOfWeek < DayOfWeek[1] then weeklyHigh = Highest[BarIndex - lastWeekBarIndex](dailyHigh) // weeklyHigh = Highest[BarIndex - lastWeekBarIndex](High) lastWeekBarIndex = BarIndex ENDIF

  Thanks

  Hi,

  to be sure, a screen capture of what was observed (what instrument and when) would help to answer, but without it, the only thing I can think of when reading this piece of code is:

  if dailyhigh has been defined as Dhigh(1) (previous day) then

  weeklyHigh = Highest[BarIndex - lastWeekBarIndex](dailyHigh)

  1	weeklyHigh = Highest[BarIndex - lastWeekBarIndex](dailyHigh)

  would only include highs from day before lasttweekbarindex until previous day when searching the highest of this selection, but not today’s high.

  weeklyHigh = Highest[BarIndex - lastWeekBarIndex](High)

  1	weeklyHigh = Highest[BarIndex - lastWeekBarIndex](High)

  would include all highs from lastweekbarindex until today when searching the highest (but not high from day before lastweekbarindex).

  So not knowing if it matches what you observed, I can only guess it is possible the differences you saw occured when current day high read by code was higher than any high from lastweekbarindex until previous day, or when a high the day before lastweekbarindex was higher than any high between lastweekbarindex and current day.

  Hi Noobywan,

  Thanks for your explanation. It seems by using Dailyhigh should be more realistic.
