Plotting the previous day high/low on intraday chart

  Hello!

  With the great help from this forum I have the indicator below on my charts. Thanks!

  But I realise I need some modification which I am struggling with. What I want is that the line of the previous high and low should be drawn (one single horisantal line not connected with the other days) on each day, not just the current day. Keeping in mind that the day in the intraday chart should be defined as midnight to midnight according to the set timezone.

   

  Anyone could help me with this?

  Thank you!

  Hi Tom,

  When I use your indicator, the “previous high” and “previous low” are already drawn every day… (or do I not understand your question?)

  By the way, a very good and effective indicator…

  Yes, sorry for the confusion. It does that, my mistake with setting it up.

  But is it possible to get rid of the connecting lines between the different days? I only want the horisontal lines.

  Hi Tom,

  In its current form, that is not possible…

  Otherwise, you have to calculate the whole indicator differently using arrays…

  Hi, I  used this trick with some indicator sometime ago and it worked:

  if opentime >=235900 and opentime <= 000100 then //if we work in the 1min TF alpha = 0 else alpha = 255 endif ..... return prevh coloured (0,0,255,alpha) //repeat with the rest of the lines

  1 2 3 4 5 6 7 8 9

  if opentime >=235900 and opentime <= 000100 then  //if we work in the 1min TF alpha = 0 else alpha = 255 endif   .....   return prevh coloured (0,0,255,alpha) //repeat with the rest of the lines

  As you see the trick is just zero the alpha (intensity of the color )  between the last and first candles of the day (235900 and 000100 in the 1 min TF) to hide the ugly vertical lines.

  below snippet is simple and works on all TF’s  😉

  alpha= 255 if opentime =000000 then alpha = 0 endif ..... return prevh coloured ("blue",alpha) //repeat with the rest of the lines

  1 2 3 4 5 6 7 8

  alpha= 255 if opentime =000000 then   alpha = 0 endif ..... return prevh coloured ("blue",alpha) //repeat with the rest of the lines
