That is very nice code Reinsley and yes I think your T3cross HiLo ribbon captures the trend nicely on my daily chart. You are obviously a long way ahead of me with AFL and I will learn a lot I think when I study your code.
I see now how to plot text as you have done( and be able to define font size which was a later project for me - so thanks) But, I want to use AFL to place it automatically above or below each swing on a Gann chart - or even on the zig zag chart. Maybe it is not possible but I have seen this on several other software packages and would like to see it in Amibroker :) The most important would be days/bars for the swings to form and the range of each swing (R 80,TD6 for example). So the formula would need to be able to count the bars and also calculate the range in each swing.
