I see plenty of mentions of their categorical dual, i.e. co-mbinators like y-combinator, etc. But no one seems to give an example of an mbinator? Even wiki.haskell.org/Combinator doesn't mention it.

The etymology doesn't involve "co-". I guess you could ask about "binator", which might make pairs without putting them together. But that's not a very useful concept.

I apologize if the title is a little confusing, but hopefully that highlights the point of my question. If a method has recursively called itself multiple times and some base case is reached that causes all recursive calls to return/'undo', what would be a proper term to describe that?
Exiting, undoing, and unraveling recursion all come to mind, but I'm mostly wondering if there's an agreed upon term for it that I can use in comments. Thanks!

I know that you're not supposed to be doing this but since I almost exclusively trade based on daily and weekly data, I think I'd be getting a more realistic idea of trading ideas if I were able to execute on the same bar instead of buying on next day's open. Thanks!
You can add allowMagicalThinking=TRUE to your call to applyRules. If you add allowMagicalThinking=TRUE to your call to applyStrategy, it will be passed to applyRules.

It's not available on the lower left screen thingy. If I do po self.delegate.tvDelegated it doesn't work either.
It's simple looking at some variable value. What's the problem?
Sometimes is better to use the original method sending, instead of dot notation, even if in the latest version support mors dote, try to write
po [[self delegate] tvDelegated]
