On the same day of September 3rd, I bought a call option on the AUDUSD for two days expiring September 5th. The spot was 0.8982, breakeven was 0.9032 and the premium was 50bps.
On September 4th about 11pm Singapore time or 11am NY time, I decided to sell the option as the spot was at 0.9180, I made a yum yum profit of 148bps or a 2.96X payout, not bad at all. My initial expectation was between 2X to 2.2X.
