Quote from RichardRimes:
If you have a good reason to buy back sure...if you don't have a good reason to buy back...no. I can't think of a good reason to buy them back. It cost to buy them back plus comission. The big thing with calendars is patience. I look at it every day because its there...but have no plans to do any trading on it until mid/early sept.
edit: OCT will come out after Aug exp..THATs when you'll look to roll
Rich,as I am sure you know,when you are long a calender spread you are generally,
Long Vega
Short Gamma
Short theta
Apx Delta flat
And have risk only up to the debit of the spread
As i said generally,i am assuming the strikes of both options are close to ATM,and the spread is not a diaganol spread...
Essentially,when you have a long time spread you are running a short time decay trade with limited risk..and profit...
If the short theta aspect of the trade is what appeals to a trader than one should know when the "greeks" start to change and the trade becomes long theta and you start to bleed..
You should also know what the maximum trade potential is from the day you put the trade on..Yo need to simulate on day 1,what the value of the trade would be on the near term option expiration day assuming the stock is at strike.That is the max you will make .You already know what you can lose,so its very easy to decide what your risk reward ratio is...You may want to drop vol a couple of handles to be conservative.
With all this said,you should always look at the calender and see what percent it is trading at vs your "max" value.If its trading at 80% of max value,you are risking quite a bit to make very little.
In the trade mentioned above where the near term option is trading at .15,I would certainly look to see if the greeks had flipped and you are now bleeding time decay.If you are,one should really think about keeping the position on or rolling,or even taking a shot with a stop...But in NO WAY should you ever let commisions influence your decision,especially at 1 per contract...That is a cardinal sin of trading
With that said,when one option get
