As I mentioned in my first post, I am trying to learn calendar spreads. So, I will not be able to answer your questions precisely.
However, what I gather so far is:
1. These strategies can be used to generate income without taking unlimited
risk.
2. I still have to figure out whether margin requirement will be less than that for Iron Condor.
3. From Sabharwal Saheb's excel sheet, it is clear that max loss will not exceed initial debit, something like buying a naked option.
4. Like any other strategy, one will have to figure out how to handle the trade
by experience.
5. Rather than fixed stop loss, one can decide to close trade with pre decided
profit or loss. I entered into a paper trade on 28 JULY as follows;
sell Aug 8000CE @ 35.90
buy Sep 8000PE @ 45.50
sell Aug 7500PE @ 38.00
buy Sep 7500PE @ 65.50
On 28 Aug, Max Profit ; 5011
Max loss : 1855
Return on 1 Aug was 1290.
Assuming margin req of 50,000 (it should be less), profit is 2.5 %. So, one might decide to take the profit and move on to the next trade.
Let us exchange any more ideas the members may have on the strategy.
Thanks and regards
