Basic library for the visible range chart; with functions to allow plotting Fibs from body high/low as well as wick high/low
-Thanks to code from @PineCoders Visible Chart library (PineCoders/VisibleChart/4), which is a much more comprehensive library than this, but which does not include some functions that I find useful:
-Added the following exportable functions: highest/lowest body, highest/lowest close, highest/lowest open. These allow one to anchor fibs from bodies rather than wicks -Added a Fib Box function in the example code
The above chart shows the example code plotting a Fib range drawn from bodies and a highlighted retracement zone (61.8 % - 78.6% )
this script won't execute when the chart gets refreshed due to the network reconnected or a weak network connection. specifically the chart.left_visible_bar_time will be breaking the whole script. looks like a pinescript bug or something.
