Not sure if this one has been posted here yet? I did a quick look and couldn't see it. Sorry if it's a repost. Pretty robust indicator, and it has a button! The strategy/system which it was customized for has a good thread over at FF which is worth a read for anybody who is into the centered TMA (look for SwingMans lazyTMA).
Also, forgive me for not knowing but can anybody tell me if this other version of the centered TMA is different from the standard centered TMA? And if so, how it is different? It would be nice to find a version of it which has alerts/arrows for crossing the outer bands (in and out), as well as alerts/arrows when crossing the center.
