Here is another classic indicator by Mladen - the T3 Oscillator. Apologies if this was posted before but I couldn't locate it on our site so I'll post it here including screenshot as it comes with an example.

As explained by Mladen:
T3 oscillator ...

First I though to make a version of awesome oscillator using T3, but then, when I tried it, it turned out that with awesome oscillator calculating lengths (5,14) it is too fast. So decided to open lengths as parameters and to use other default calculating lengths.

This is how it looks like with default parameters
