Thank you Jgills. A very helpful reply.
The folks at CBOE explained the use of the word vertical to mean that the options used in the collar expired on the same date.
Ok, that does make sense. I was under the impression that the dates being the same was a given, but now you've helped me a bit too, so thanks.
Good luck with your trade, make sure you know the payoff structure you get into before making you trade.
If I owned a put, I wouldn't call it a bull call spread, etc, etc.
