Not at all!
Why? - as stated in the post and by Jimmy and MrTools many times - this isn't really "repainting" but simply the fact that an H4 candle will close after 4 hours - so if you have this on M15 then SOMETIMES (for example roll over/change of colour) you will experience what looks like repainting. (Mostly, though, i. e. during an extended trend move colours will remain stable once the direction has established itself.)
The "problem" that still remains with your
4TF HMA (and some others of your 4TF) is that the arrows stay on screen even after the signal has changed (they should disappear - some will continue to call this "repaint", of course).
You adapted the ones aiming up (they now disappear) but for some reason or other (the ones aiming down) still stay after the signal situation has altered.
I use it despite that but better would be better, of course.
