With the latest added features chart.left_visible_bar_time and chart.right_visible_bar_time it is now possible to
place label.new() positions at the equivalent of 'location.top' and 'location.bottom'
The following are examples of functions which enables to find the visible chart highest/lowest bars:
highest_visible_chart() =>
var float highs = na
highs := time == chart.left_visible_bar_time ? high :
time > chart.left_visible_bar_time and high > highs ? high : highs
lowest_visible_chart() =>
var float lows = na
lows := time == chart.left_visible_bar_time ? low :
time > chart.left_visible_bar_time and low < lows ? low : lows
In this example labels are plotted when a sma crosses another sma
Also combined with 3 boxes, scrolling gives insights how the features work
