Greece has gained the European Central Bank's approval to reopen the Athens stock market after a month-long shutdown, with restrictions on trading by local investors, an official at the exchange said on Tuesday. The Athens stock exchange has been shut since June 29, after the government shut banks and imposed capital controls to prevent banks from collapsing in the face of mass withdrawals. Greek regulators offered two different plans for the re-opening - one allowing unrestricted trading and a second that imposed restrictions on trading by Greek investors to prevent capital fleeing banks, sources said earlier.
