Quote from Notes123:
I asked my broker about the idiot who bought 25 contracts before the report, and my broker, being a hacker for years before joining the brokerage firm, managed to track down the buyer and followed his trades of the day. Here is what the broker found about the trader:
1. The trader covered the 25 contracts for a profit because he shorted earlier about 20 minutes before the report was out. I guess he was worried that his winner would turn into a loser after he saw the price inching up before the report from .15 to .38.
2. After the report, the price dropped, the same trader shorted 25 contracts (he liked to trade 25 contracts at a time, obviously), at the price of .85. The trade went into profit briefly (a few seconds) and then went into red when the price rebounded.
3. The trader held on to his short position. I guess the inventory number was so bearish that many traders thought of only one direction: down.
4. My broker found that the same trader didn't have any trading activity until hours later: He covered his 25 contracts, at a loss of about 40k.
Who would think the oil price would go up relentlessly after a very bearish inventory report?
