Extra Extra Pass, pass, don't miss! The Japanese IT industry's dog blood gossip continues to be the exclusive broadcast!!

A 10-year lawsuit was finally put to a full stop September 3, 2015, as the Tokyo Supreme Court dismissed Mizuho Securities ' appeal and upheld dismissing's verdict. This precedent will have a profound impact on the IT industry: who should be responsible if the bugs in the program cause huge economic losses? User? Operators? Or a system developer?

BUG: Errors in computer programs

The protagonist of today's story is Mizuho (Mizuho) Securities, the Tokyo Stock Exchange (hereinafter referred to as the East certificate), and Fujitsu.

Everyone of Fujitsu's classmates, lei son really is not Fujitsu Black AH. Your company in the industry first, more projects, so the number of points ah! If it hurts your feelings again, see if you can forgive me.

Well, it's all said, and the following is officially started.

　(a) Mizuho Securities ' case of the Black Dragon

If the time can turn back, let Mizuho Securities trader Tanaka-San (pseudonym) through the December 8, 2005 to the east before the opening of the first few minutes, Tanaka-San will choose to put their own that the black dragon finger to break it?

Oolong finger (fat finger): Refers to the stock trader, trader, shareholders in the transaction, accidentally knocked the wrong price, quantity, the direction of buying and selling.

It was due to a false input from Tanaka-san that his Mizuho Securities suffered an astronomical loss of more than 40 billion yen. Although the yen was painted in the same denomination as MINGBI, 40 billion yen was still worth some silver (about 2.7 billion yuan at the prevailing exchange rate).

This is the day the Japanese company j-com initial public offerings. 9:27, it's a few minutes from the opening. Tanaka-San received a client's commission: "Sell 1 shares of j-com at a price of 610,000 yen." Tanaka-San received the Commission, in the Mizuho Securities Trading terminal, mistakenly entered the "1 yen per share price, sell 610,000 shares."

After the order is issued, Mizuho Securities ' trading software checks that this is an unusual trading order and gives a warning dialog box. However, like the Mizuho Securities trader this level of trader, playing is not in accordance with the pattern of cards, the daily Warning dialog box is too much. Tanaka-San did not even read the contents of the dialog box and pressed the OK button. As a result, this huge sell list hangs on the trading handicap of the East card.

2 minutes later, Tanaka-San found the error and hastened to try to revoke the sell order through the trading software. However, the continuous input of 3 withdrawal orders, were rejected by the East Card trading system (later found to be due to the trading system bug).

Tanaka-San also quickly called the exchange's head, requesting that the sale be withdrawn. People on the exchange said: "We have no right to operate, this problem can only be done by yourselves."

Then the handicap trading has begun. The huge sell-off first set the opening price at 672,000 yen, then all the deals in turn, and eventually nailed the j-com's stock to 572,000 yen. (unlike the celestial world, Japan's rising and falling prices are not strictly calculated according to 10%, but the price range of an integer is determined by the open prices)

There is a big mess in the market at the moment. The retail investors were frightened by the huge empty single, thinking that j-com company had something wrong, followed by a sell. Some institutions and large ones have guessed that they are out of the black Dragon, quickly buying at the price of falling. Some moral integrity institutions, such as Deutsche Securities, bought a few hands and felt it was too unkind, consciously stopped snapping. And most institutions have said: moral integrity only how much money a catty, there is no cheap eight eggs Ah! It was a pleasure to rob.

Maybe some students do not understand stock trading, probably is the following bright.

Originally, the client's commission is the following ...
