@raikrau, I can no longer manage access to the indicator with just a 'Pro+' subscription, so here is the code for everyone, just open the Pine Script Editor, paste it in, save it and add to your chart. Good luck :)
// Global settings
study(title = "DailyATR", overlay = true)
// Indicator input parameters:
// - ATR moving average period for ATR smoothness;
atrMAPeriod = input(14)
// - ATR timeframe to be used. Allowed values are (case sensitive!) 'D' for daily, 'W' for weekly, 'M' for monthly.
// Others values are also possible, but not tested.
// Note: there's seems to be a bug in Pine Script that not allows to use a preferrable form:
// atrTimeframe = input(title = "ATR timeframe", defval = 'D', options = ['D', 'W', 'M'])
atrTimeframe = input(title = "ATR timeframe", defval = 'D')
//atrTimeframe = input('D', type = resolution)
atrMultiplier = input(title = "ATR multiplier", defval = 1.0)
// ATR of needed period and timeframe
tfATR = security(tickerid, atrTimeframe, atr(atrMAPeriod))
// Open, High, Low and Time of needed period accordingly
tfOpen = security(tickerid, atrTimeframe, open)
tfHigh = security(tickerid, atrTimeframe, high)
tfLow = security(tickerid, atrTimeframe, low)
tfTime = security(tickerid, atrTimeframe, time)
// tfOpen in a new period start bar and NaN in any other bar
tfStart = (change(tfTime) != 0) ? tfOpen : na
// Data from a dayly chart - to define where days start
//dayOpen = security(tickerid, 'D', open)
//dayTime = security(tickerid, 'D', time)
// dayOpen in a day start bar and NaN in any other bar
//dayStart = (change(dayTime) != 0) ? dayOpen : na
//cryptovolatility.net // Maximal and minimal price from the period start
maximumClose = na(tfStart) ? max(maximumClose[1], close) : close
minimumClose = na(tfStart) ? min(minimumClose[1], close) : close
// Line colors calculation - transparency depends on line broken or not
upperColor = (maximumClose > upper) ? color(green, 0) : color(green, 0)
lowerColor = (minimumClose < lower) ? color(red, 0) : color(red, 0)
// Upper and lower lines draw
plot(upper, color = upperColor, linewidth = 1, title = "High", style = circles, join = false, editable = true)
plot(lower, color = lowerColor, linewidth = 1, title = "Low", style = circles, join = false, editable = true)
// Period open price draw
plot(tfOpen, color = black, linewidth = 1, title = "Day Open", style = circles, join = false, editable = true)
//plotshape(dayStart, text = "test", color = black, size=size.tiny, location = location.abovebar, style = shape.circle, textcolor = black)
