Plan to take off trade b/f earnings in Feb 1-5 date not yet confirmed.
If underlying stays relatively in the same spot will yield approx. 50%

1/07/08
NYX dropped down btwn my short put and FEB expiration b/e point. Made the following adjustments:
STC -1 the 90 FEB/MAR Call calendar @.89
originally bot for 1.30
total loss debit for 90 feb/mar call calendar = .41

rolled the call callendar down to closer ATM:
bot +1 FEB/MAR 75 call calendar @1.31 (mark 77.63)
leaving a double calendar at 75 CALL and 80 PUT
current debit for trade (including roll debit) = 2.97
(see left picture for current P&L graph for position)
Placed a STOP order in @1.85 (approx 40% loss) plan to close b/f this is hit if market keeps falling. Will want to see NYX settle into some sort of range, ideally in the 20% range I have calendared btwn. 70 and 85
