Thank you for your work on this Indicator, Alexander.

Quick question:

Is this version a translation of the code I provided in my request, or the link to the trade-profit website?

[Alexander.Gettinger]

This is a translation of the MT4 code.

Alexander,

Is it possible to get a MTF version, so we can choose to have the indi show trend for a different TF than the chart it's on?

Thanks in advance,
bonnevie
