Quote from jeffalvinson:
2: Use front month SPY options in the 1.35 to 1.85 cost range
that have high trading volume (10,000 to 30,000).
They will usually have a .01 bid to ask spread (that's important)
I noticed that through the day today the Bid-Ask apread was about .04-.06 on all the contracts. I would gusess that's due to a relatively volatile market today (SPY off 3.05, the DJX off 3.16.)
In any case the SPY B-S spread is, as you and others have pointed out much narrower than other options such as the DJX, MNX, etc.
My question to you is, since the SPY options are American style, i.e. can be exercised at any time, how do you handle your OTM and ATM trades as the expiration date nears (if you've not already taken your profits out of the market.) Do you have or use a target date (e.g. 3 days before expiration, 5 days, etc.) to get out regardless of the profit or loss.
Also, would you (or do you), in the case of a credit spread, buy back the short and leave the long leg in place just in case the market made a large move in the long position's direction.
Thanks.
Best
