 JMA (Jurik Moving Average) is Mark Jurik's flagship adaptive smoother, recovered through decompilation of his proprietary AmiBroker/MetaTrader binaries. Unlike forum-sourced approximations that use exponential volatility smoothing, this implementation maintains a 128-bar volatility distribution and applies percentile trimming to derive a robust reference. The result: identical behavior to Jurik's commercial software within floating-point tolerance, including spike rejection during 3-sigma events where approximations diverge by 3-4%.
