  Hope somebody can help me

  How can i display a Donchian Channel with xPeriods that do not print channel on the resent candlestick like in attached example file

  How have to change the code?

  Upper = HIGHEST[a](HIGH[1]) Lower = LOWEST[a](LOW[1]) Middle = (Upper + Lower) / 2

  1 2 3

  Upper = HIGHEST[a](HIGH[1]) Lower = LOWEST[a](LOW[1]) Middle = (Upper + Lower) / 2

  Your code is fine, but you cannot use RETURN since it will not allow you to skip the current candle.

  You’ll have to use DRAWSEGMENT, instead, to plot data between the second last candle and the previous candle.

  Try this (not tested):

  Upper = HIGHEST[a](HIGH[1]) Lower = LOWEST[a](LOW[1]) Middle = (Upper + Lower) / 2 If barindex > 2 Then Drawsegment(barindex-2,Upper,barindex-1,Upper) coloured(0,0,255,255) Drawsegment(barindex-2,Lower,barindex-1,Lower) coloured(0,0,255,255) Drawsegment(barindex-2,Middle,barindex-1,Middle) coloured(0,255,0,255) Endif Return

  1 2 3 4 5 6 7 8 9

  Upper = HIGHEST[a](HIGH[1]) Lower = LOWEST[a](LOW[1]) Middle = (Upper + Lower) / 2 If barindex > 2 Then    Drawsegment(barindex-2,Upper,barindex-1,Upper)   coloured(0,0,255,255)    Drawsegment(barindex-2,Lower,barindex-1,Lower)   coloured(0,0,255,255)    Drawsegment(barindex-2,Middle,barindex-1,Middle) coloured(0,255,0,255) Endif Return

  But you won’t be able to change the style of plotted lines in versions prior to 11.

  Thank you very much Robert,

  is it possible to draw lines without brakes (like in “original” Donchain)?

  Unfortunately segments are straight llines, so it’s not possible.

  You cannot, since there’s an instruction to allow drawing object only on the last bar, but then you wouldn’t see the previous bars, only the last one drawn. It is useless in your case.

  If we display a price label everytime your chart would become so messy!

  Try this modified version:

  Upper = HIGHEST[a](HIGH[1]) Lower = LOWEST[a](LOW[1]) Middle = (Upper + Lower) / 2 If barindex > 2 Then Drawsegment(barindex-2,Upper[1],barindex-1,Upper) coloured(0,0,255,255) Drawsegment(barindex-2,Lower[1],barindex-1,Lower) coloured(0,0,255,255) Drawsegment(barindex-2,Middle[1],barindex-1,Middle) coloured(0,255,0,255) Endif Return

  1 2 3 4 5 6 7 8 9

  Upper = HIGHEST[a](HIGH[1]) Lower = LOWEST[a](LOW[1]) Middle = (Upper + Lower) / 2 If barindex > 2 Then    Drawsegment(barindex-2,Upper[1],barindex-1,Upper)   coloured(0,0,255,255)    Drawsegment(barindex-2,Lower[1],barindex-1,Lower)   coloured(0,0,255,255)    Drawsegment(barindex-2,Middle[1],barindex-1,Middle) coloured(0,255,0,255) Endif Return

  You could create a separate indicator that just draws the text of the value you want on the last bar only then apply it as a separate indicator to the price chart as well as Roberto’s last code.

  defparam drawonlastbaronly = true Upper = HIGHEST[a](HIGH[1]) Lower = LOWEST[a](LOW[1]) Middle = (Upper + Lower) / 2 If barindex > 2 Then upper1 = upper[1] lower1 = lower[1] middle1 = middle[1] DRAWTEXT(" #Upper1#",barindex,Upper,SansSerif,Bold,11)coloured(0,0,255) DRAWTEXT(" #Lower1#",barindex,Lower,SansSerif,Bold,11)coloured(0,0,255) DRAWTEXT(" #Middle1#",barindex,Middle,SansSerif,Bold,11)coloured(0,255,0) Endif Return

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

  defparam drawonlastbaronly = true Upper = HIGHEST[a](HIGH[1]) Lower = LOWEST[a](LOW[1]) Middle = (Upper + Lower) / 2   If barindex > 2 Then upper1 = upper[1] lower1 = lower[1] middle1 = middle[1]   DRAWTEXT("                         #Upper1#",barindex,Upper,SansSerif,Bold,11)coloured(0,0,255) DRAWTEXT("                         #Lower1#",barindex,Lower,SansSerif,Bold,11)coloured(0,0,255) DRAWTEXT("                         #Middle1#",barindex,Middle,SansSerif,Bold,11)coloured(0,255,0) Endif Return
