The Tokyo Stock Exchange announced Tuesday it will increase its maximum trading volume from the current 14 million transactions a day to 17 million in the fall, following the bourse's conversion into a holding company in October.

The upgrade is seen as an effort by the TSE to wipe out the black mark it suffered when a computer glitch forced a suspension of all stock trading for half a day in November 2005.

In January 2006, the TSE was forced to halt trading in Livedoor Co. shares when a flood of sell orders overloaded computers after the Internet startup was raided over alleged securities law violations.
