Here is another interesting one by Mladen called the Smoothed MA Distance Levels (Oscillator) for MT4.

It's a non-repainting indicator which was kindly optimized by Mladen and he made it so that the levels adjusted to the last value of the Standard Deviation. This makes the levels sort of "Dynamic" if you'd like to call it that and they are subject to change depending on the last bars of the Standard Deviation's value.
