Now let's take a look at the Options Chain from 2013.07.08
So $OKE closed at $41.42 and check out the volume in the Aug 45 calls: 6,346 calls traded with OI(open interest) only 142 and most of them were bot at offer price around $0.50.
The following day OI rose to 5,544, meaning that 5,402 calls were bot to open at $0.50 for $270,100 "investment"
We can see those Aug 45 calls are closed at $4.50 turning that $270,100 investment into a $2.43M or about $2.16M profit (800%) in 17 days.
What a lucky! ;)
