Excuse me but could you advise whether the current version of the DonchianRectangle is compatible with N7? I'm trying to import the 6.5 version to no avail but the problem could definitely be ME. In any event many, many thanks for your work and contribution to my trading methodology that is slowly evolving.

See here

Inside Bar convert from MT4 Plots high and low of the last n bars. You can set n=3 to obtain your indicator. This is a version for NT7, but you can just edit a new indicator with NT 6.5. and then copy the code.

Thanks for your response.
Turns out, as feared, I was using the version 7.
I'll figure it out. Thanks again.

I got this thingy working once you implied it was possible, vegas.
Very helpful on the eyes.
Thanks to you and all that made it possible.
