In this tutorial, we are going to look into a mild variation of Double Diagonal Spread to take a neutral to the bullish view. Double Diagonal Spread is a 4 legged option strategy and nothing but a combination of bull call diagonal spreads and bear put diagonal spreads which is more of a neutral approach towards trading.
Let see how we can take a mild bullish bias with a slight variation in Double Diagonal Spreads.

Lets get some primer on Diagonal Spreads and Calendar Spreads before jumping into the actual trading strategy example
A calendar spread is a strategy involving buying longer term options and selling equal number of shorter term options of the same underlying stock or index with the same strike price
A Diagonal spread is a strategy involving buying longer term options and selling equal number of shorter term options of the same underlying stock or index with the different strike price
A Double Diagonal Spread is a neutral approach combining two strategies Bull Call Diagonal Spread + Bear Put Diagonal Spread and here is the sample payoff graph. It can also be viewed as short strangle in a short month options contract (For example . current month contract) hedged with long strangle on both sides in the long month options contract (for example next month contract.)
