It's definition is fairly simple and one can be (among other places) be found here : Triangular Moving Average -
Description of the Triangular Moving Average (TMA) . Here is how a normal triangular moving average looks like on a chart :Now, at some stage of TA development people like Hurst and Brian Millard were thinking how can that be made better (since obviously there is a lag in the data that TMA is calculating - the most significant price in calculation is in the middle if the length so it is a half way from the current price, current price has less weight in that calculation) and they came to an idea that was already used in some other indicators : to "center" it.
Now centering is simply shifting values to the left on the chart by half length bars and after doing that it looks like this : As it is obvious, by shifting it to the left, it fits perfectly the data but it starts lacking data from the right. And then comes in the centered version of triangular moving average ...
Does TMA repaint?
No, but the "Centered" TMA (in any version) will always REPAINT (see the post below).
