Zecco Trading makes millionaires for a day

What would you if you logged onto your brokerage account on April Fool's Day to find that your balance had suddenly increased by millions? This was the experience of some customers of the discount brokerage Zecco Trading, leading many to conclude the company had pulled the stupidest April Fool's joke in history.

However, the company was quick to post a notice acknowledging that some accounts were showing incorrect balances, and it denies that the error was intentional. More worrisome, imho, was that at least one customer that had suddenly been graced with millions of dollars placed an order for a million shares, which was carried out without question. Bit of bad programming, that.
