"Strategy Looks good on Paper" very well said may be we could add the word "only" also somewhere in the sentence
No,no. Strategy can be traded BUT with an other plan. Just to give an idea:
Entry:
Spot at 5350: Sell 5400 call.
Market falls to 5150: Sell 5100 put.
Now you have your short strangle and you collected already more premium then given in your example.
Depending now what the future does, you have different choices. Lets take just one idea:
If market moves up from spot 5150 you go long the future. Here you have to have a clear idea about what the future is going to do. Understanding of TA is surely a help to that.
Now, the premium collected from the sold put stays in your pocket as market now moves up and simply spoken, the premium from the sold call stays with you, as you now have the future to take the up move.
