  nope. Of everything that is displayed on the screen. So if I move / zoom the chart, the highest/lowest might change. have a look to the screenshot, I think it is pretty self explanatory

  No, any code CANNOT read what’s on your charts. It only knows OHLC, Date and Time.

  No input is available.

  Hi,

  You can use the “BarIndex” to determine the high and the Low…

  High Low

  DefParam DrawOnLastBarOnly=True xHigh=Highest[BarIndex+1](High) xLow=Lowest[BarIndex+1](Low) DrawText("High=#xHigh#",BarIndex,xHigh,SansSerif,Bold,16)Coloured("Green") DrawText("Low=#xLow#",BarIndex,xLow,SansSerif,Bold,16)Coloured("Red") Return

  1 2 3 4 5 6 7 8

  DefParam DrawOnLastBarOnly=True   xHigh=Highest[BarIndex+1](High) xLow=Lowest[BarIndex+1](Low)   DrawText("High=#xHigh#",BarIndex,xHigh,SansSerif,Bold,16)Coloured("Green") DrawText("Low=#xLow#",BarIndex,xLow,SansSerif,Bold,16)Coloured("Red") Return

  Hi,

  Copy the code and save as an indicator in PRT, then add the indicator to the price… (top left of the graph)

  Hi,

  Because you use 1k units with a timeframe of a week (28 years of history), the “High” and “Low” are far out of the picture (but they are there)… Try it with fewer number of units so that the values come into view…

  That would not be of the chart; it would be of the internal data the chart is fed with. benkunz asks for the viewport of the chart.
  As far as I know this is not possible (although I would be able to make some surrogate hence “almost right” thing).

  benkunz, maybe consider why you would want this. A high-low is the most normal thing to want. But not from a random chart-width (for number of bars). Please look below, at the purple lines. Have a special look at the vertical purple line. This is where the high-low calculation starts in my case. For this chart 25 bars (25 x 5 minutes in this case) ago.
  What you want would be far more sophisticated. It would require the knowledge of the first bar on the chart and the last bar on the chart (while you scroll towards history and back). I don’t think that is possible.

  Hi @benkunz

  Then you better wait for the “almost right” solution from PeterSt…

  Rightclick in the right-hand margin, then “configure this area” (bottom option) and then untick what you see at the mouse pointer.

  How does the BarIndex variable work ?

  from what I read, it is supposed to count the number of candles on the chart. But when I zoom in the reduce the number of candles on my screen, the BarIndex still shows the same value. I added this to the indicator to follow the value of BarIndex :

  DrawText(BarIndex,BarIndex,xLow+100,SansSerif,Bold,16)Coloured(“Red”)
