Thanks @Geoffrey. I have seen this video and used it as my starting point. I am reviewing his other tutorial videos to validate what I have done.
As an update, the core leg counting logic lines up so far with what byebyemoney has put out. The missing pieces relate to coloring the leg numbers. For instance, on up legs, he uses dark green to indicate second entries and light green to indicate a normal pullback(?). I have decided that this could be included a later release.
On the business side of things, I do plan to charge for this indicator. It has taken many hours of work and I expect many more to come to make it better. Not sure what the price point will be yet. It won’t be as much as what bbm charges, but enough to make it worth my while and to provide the tech support that will sure come. I am leaning towards a lower cost monthly subscription option.
