TMA center channel bands

Here is another channel upper and lower bands indicator, this one is made of a centered Triangular Moving Average with classic deviation from this mean, made of plus and minus ATR multiplicated value. Quiet popular in the forex trading community, it is the base of many more or less sophisticated strategy, do your homework with this one, you’ll find it is valuable for different market phase.

Hello
please have you got the opportunity to modify code in order to obtain a centered simple moving avarage? thanks

Hi! Can you explain the ATR length and ATR half length? Should one of these nbit be the number of periods linked to TMA?

Wolf • 02/13/2016 #
Just for information:
This calculate code is interesting, but it is not a Triangular Moving Average, but A Weighted Moving Average.
Nowadays with new version of PRT
So, to reduce the calculate time. It is possible to cancel from line 6 to 16 and change line 18 by:
Buffer1 = WeightedAverage[HalfLength](close) or
Buffer1 = average[HalfLength,2](close)
Thanks

  Hola Lobo, soy nuevo en programación, pero me interesa ese indicador, en tu mensaje estas hablando en la modificación de código para adoptarlo a la nueva versión de prt, podrías colgar el código modificado competo please?
