Hello,
in order to have an ninjatrader (C#) denoising/smoothing indicator i search a good coder/scientist who have the ability/skill to adapt some wavelet transformation to forex price(in order to have a kind of clean curve in real time)..
The only example i can provide is  http://demonstrations.wolfram.com/WaveletShrinkageDenoising/
By the way and as I try many filtering method (from ehlers to kalman) and have no new clear ideas if you know some others effective methods i'm completly open..
thanks
