I made this script a long time again and never released it. It is a ABC Pattern finding tool. You can adjust the "Bars Back" setting to include more or less bars in the pattern. I usually have it set to 10 or 15 these settings seem to work well on most assets. The scripts allows you to set up a trade box automatically and has a call out table to make prices levels more clear and easy to read. The trade box levels can be set by fixed percentage or by pattern based fib.
Hope it helps!
