|SYNTAX||Percentile( array, period, rank )|
|FUNCTION|| The Percentile function gives rank percentile value of the array over last period bars.
rank is 0..100 - defines percentile rank in the array
Performance note: the implementation of percentile function involves sorting that is relatively slow process even though that quicksort algorithm is used.
Since version 5.92 Percentile supports variable period.
Note that Percentile is very computation intensive function (it involves re-sorting arrays every bar) and variable-period version (if you call it with period being ARRAY) runs slower than scalar version

The Percentile function is used in the following formulas in AFL on-line library:
