/*
The basic definition of an 'up' fractal is a bar high that is both higher than the two bars immediately preceding it
and higher than the two bars immediately following it.
The lows of the bars are NOT considered in determining the up fractal progression.

If two bars in the progression have equal highs followed by two consecutive bars with lower highs,
then a total of six bars rather than the usual five bars will make up the progression.
The first High becomes the counting fractal. Reverse for 'down' fractals.

The 5 bar formation works best on Daily or longer time frame charts.For intraday data charts we often use 9 bar, 13 bar and 21 bar formations for fractal counting
