In derivatives trading, the term diagonal spread is applied to an options spread position that shares features of both a calendar spread and a vertical spread.It is established by simultaneously buying and selling equal amount of option contracts of the same type (call options or put options) but with different strike prices and expiration dates.
The iron butterfly is a special case of an iron condor (see above) where the strike price for the bull put credit spread and the bear call credit spread are the same. Ideally, the margin for the iron butterfly is the maximum of the bull put and bear call spreads, but some brokers require a cumulative margin for the bull put and the bear call.

An option spread shouldn't be confused with a spread option. The three main classes of spreads are the horizontal spread, the vertical spread and the diagonal spread. They are grouped ...

If, instead, the trader executes this strategy by buying options having expiration in one month but writing (selling) options having expiration in a different month, this is known as a ratio-diagonal trade. As with all option spreads, the trader in a ratio-spread will strongly prefer to buy options having a distinctly lower implied volatility ...
