I wouldn't say big bucks but I did manage to short Crude Oil at around 103 on the April 22 and closed the position Thursday at around 99.8. I was also short Orange Juice starting on the 25th of April and closed the position also on Thursday. Not big bucks but more money than I make on my job in even a month.
Good job, that short crude oil trade alone represents $3000 profit per contract! Did you use a mechanical trading system?
