Actualizado How To Color Prior Bars

Example how to color the trigger bar of the condition and n-1 prior bars using only 1 barcolor() function.
Currently when offsets are used in barcolor(), bgcolor(), plot(), plotarrow(), plotchar(), or plotshape(), the offset only works with a simple (static) integer. If series (dynamic) integers are used instead, there is not an error, but the series values are ignored. Because of this limitation of offset being constrained to using only fixed offsets, the normal way to paint 3 Black Crows would be to use 3 barcolor() functions. Since there are a known number of bars to be painted in that scenario, this can be easily accomplished.
If a condition encompassed a variable length of n bars, then the number of barcolor() functions needed to use would be unknown. How to color the trigger bar of the condition and n-1 prior bars using only 1 barcolor() function? Dual examples below solves issue but requires n "future" bars, because of this it will not paint the most recent condition in realtime and may not be applicable for use in certain realtime situations. It paints similar in behavior to how a pivot does. Special thanks to LucF and RicardoSantos for illumination!
