This may be a failure of understanding on my part, but this analysis is not making sense to me.
I can see using the boxes to convert the trade synthetically to all calls. You do this by buying the 19-21 box. Then all the puts go away, and you have 2 x a 19/21 ratio with only calls.
Coversely, selling the box converts the trade into even a bigger mish-mash of calls and puts that does not simplify anything.
If you substitute "call" for "put" in your commentary, then I can follow along, and understand, and it seems right to me.
Using puts, I just don't see a way to get unlimited risk on the upside, which is what the original trade had.
Also on the baby butterflies, they have to be done with calls as well.
+2 flies 19/20/21
+4 flies 20/21/22
+2 flies 21/22/23
-2 calls 23 (not 1 call)
You cannot get unlimited risk on the upside using puts to make the butterflies.
Anyway, the way to take the upside risk out is to buy 2 23 calls.
But that can seen by inspection on the risk graph.
I have ordered Cottle's book. I am looking forward to digging into this more. I am hoping there are some insights in there.
