The optimized variant of the Kaufman's Adaptative Moving Average by wellx - indicator for MetaTrader 4

The optimized variant of the AMA indicator by wellx. The original had undergone optimization in December 2006 to allow it to be usable in Expert advisors. The unoptimized version consumed resources and allowed to perform/optimization of an EA containing calls to the AMA in a reasonable time.

Its appearance is the same as the original.
