  Hi all,

   

  Have a qn:  does the lowest function include the current candle?  So example, if current day is Monday, and I want to find the lowest daily price last week, so I have to do lowest (6).  But the problem is lowest (6) will consider current low also.  I just want to consider the low between last monday , tues,wed,thurs,fri.  How do I go about defining this pls?

   

  Tks

  Lowest[5](low[1]) //or Lowest[5](low)[1]

  1	Lowest[5](low[1]) //or Lowest[5](low)[1]

  Thank you very much.  Now I am able to replicate the Donchian Upper and Lower Bands (blue dots)

  However, what I really want to find out is to create a narrower band of the Donchian, but keep the overall trend lines.  I use the code below.  Although the band has narrowed red dots, the look of the tighter band does not exactly match the Donchian bands.  Any advice on how I should modify my codes to correct this?   The codes are below and I have also attached the screenshot.  Thank you very much.

   

  LBand = lowest[interval](low[1]) // same as Donchian Lower Band
  UBand = highest[interval](high[1]) // same as Donchian Upper Band

  diffBand = (UBang-Lband)/Bfactor

  LBandNew=LBand+diffband
  UBandNew=UBand-diffband

  return LBandNew,UBandNew, LbandOrig, UBandOrig
