Found an error in the bands I had done along time ago, not sure if it caused repainting, but this version the adaptive price zone should be correct, also in the sync filter itself, apparently when the new mt4 came out someone made some changes that may have affected it, anyway hopefully fixed that, also changed the arrow colors to better reflect the trend (redish = down and blueish = up).

Oh and the one I posted also forgot to add your change on the mtf, this version it should be better. Please don't use on a real account until you are sure all is okay.

Added the new condition, and just a reminder, if causal = true, no recalculating/repainting and if causal = false the indicator is using centered calculation, which means it can and will recalculate/repaint.

More information from Mladen::::

It is a digital filter based on sync() function and is using a syne wave like shaped coefficients for filtering - smoothing.
The 3 most important parameters are the frequency cutoff, the filter window type and the "causal" parameter.

Filter type can be:

1. - Hamming;
2. - Hanning;
3. - Blackman;
4. - Blackman Harris;
5. - Blackman Nutall;
6. - Nutall;
7. - Bartlet zero end points;
8. - Bartlet Hann;
9. - Hann;
10. - Sine;
11. - Lanczos;
12. - "flat top".

Frequency cutoff can vary between 0 and 0.5. General rule is that the greater the cutoff is the "faster" the filter is, and the smaller the cutoff is the smoother the filter is.
