Here is another Adaptive indicator from the archives which was made by Mladen - The PA (Phase Accumulation) Double Smoothed EMA (Exponential Moving Average) for MT4.

As explained by Mladen:
pa adaptive double smoothed EMA ...

EMA like indicators are very "acceptable" for adaptive calculations since they depend only on 1 previous value and since they do not have to have a integer calculation period (unlike common belief, ema 1.5 for example make perfect sense math wise). So, decided to see what happens to double smoothed ema if it gets adapted by a phase accumulation. And it seems that the results are not bad. Result is still smooth, it is still fast and it seems to be adaptive as much as it is probably needed..

Here is an example of a 1 cycle and 3 cycle phase accumulation adaptive double smoothed emas on a same screen as a kind of a "cross following" system, and as it is seen it is rarely giving false signals. With some other choice of cycles it might be even better, but for that one would need to experiment a bit more than I did so far
