This is the Tim Morris Moving Average for MT4 which was re-coded from scratch by Mladen a few years ago.

As explained by Mladen:
It has been unrightfully neglected. Some of the properties it has (the very very quick response to sudden price changes and still very smooth in calmer periods) makes it a one of a very few that are able to response so quickly at a averaged value change (for example even the all known Jurik MA lags in some cases behind this moving average).

This version is a rewritten from scratch (a completely new indicator made) in order to avoid some of the problems the first posted version had (especially one case when the original could repaint) and it has been made a "normal" (no restrictions in bars, choosable price, and simplified code) indicator now. Along with the properties it has I think it is worth using it.
