Time-scaling into a back month 2-wide long fly[10/12/14] in the long bond. Selling the body combo into reports and buying the wings after a few days theta which typically offered a conversion of 8-10 ticks-risk on average over the life of the fly. Did this week after week, month after month. Ended up owning 900 of these at an average of 7 or 8 ticks.
Expiration week saw the contract pinned to the strike +/- 15 futures ticks. Each day of decay produced a convexity gain of $200k plus. Problem being when to unwind the trade or to wait for the lottery. Literally didn't sleep more than an hour the entire week. Resorted to asking my relatives what I should do.
Held through expiration and unwound futures the following Monday. US closed exp Friday only 6 futures ticks from pinning the body strike.
