Indonesia Stock Exchange (IDX) president Ito Warsito apologized to investors for the trading system failure the previous day, which reduced trading volume by two-thirds.
"We would like to publicly apologize, not only to the investors, but also to the public for yesterday's problems," he said on Tuesday, after a meeting with Finance Minister Agus Martowardojo.
The exchange's trading system suffered technical difficulties on Monday, causing a suspension in trading.
It has been reported that several investors are planning to file a class action law suit against the exchange for the system difficulties, which caused a loss of trading time.
Ito concurred that the problem had caused "trading to drop lower than the daily average".
"The daily average for the month of August is approximately Rp 3 trillion, but yesterday, the trading volume was at around Rp 1 trillion," he said.
