On the subject of butterfly conversions, I did one recently, so maybe the numbers from that will be educational for someone.
The details below are from memory as my journal is at the office.
3 weeks or so ago, I bought a SEP EW1335C/OCT 1350C diagonal for (0.75) debit. ES climbed rapidly afterward and I was concerned about the 1335 short. With the ES at about 1330, I was considering these two choices:
1) Close the spread for an additional (1.25) debit, making a total loss for the trade of (2.00)
2) BTC the 1335 short, STO 2 OCT1355C, BTO 1 OCT 1360C. This could be done for a total debit of (1.30) per butterfly. It still represents a total trade loss of (2.05) per original diagonal. The odds of the fly paying off are low. But the cost of this little lottery ticket was the same as simply closing the original trade, plus some extra commish (b/a spreads are included in the above prices).
Why not take the free butterfly?
And don't worry Mav...I only used half my home's mortgage on this trade ;-)
