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?
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
