AI Now Employed to Check HFT at Tokyo Stock Exchange

Only last year AI shocked the world by trouncing the world's top Go professional, a while ago the top poker player bowed to an AI program and now - stock exchanges are turning to AI devices for vital stock exchange functions.

The Tokyo Stock Exchange bared March 4 its plan to introduce artificial intelligence (AI) to cope with illegal dealings in high-frequency trading for the first time in the world.

High-speed trading at the Tokyo Trade Exchange is rising in volume roughly ten times over the past five years - roughly 95 million dealings per year.
The Japan Exchange Group has decided to employ AI to check fraudulence in high-speed trading that deals large volumes at an instant. Right now 15 inspectors at constant work only at the risk of overlooking ever-rising illegal dealings.

AI is to join trade screening effective the fiscal 2017 to speed up 20 times the preliminary checkup of illegal dealings and to learn in its process to improve precision as it operates. 

This is the first time AI is brought in stock exchange screening and the Japan Stock Exchange anticipates some positive effects in uplifting precision in overall stock exchange dealing.

Here, AI is fast advancing into yet another sector of man's life. Checking irregularities might in fact be a most promising area of work for AI. Unlike in any other sectors of industry where AI can pose a threat to humans, speed-directed stock exchange has plenty to gain from AI joining in its function. 

The issues involving AI in man's work have led me to write a column in the mother site, Zaikei Shimbun, in Japanese. The column is currently discussing AI and its effects in the world of translation. (Nathan Shiga)
