The Stock Exchange of Thailand and the online system vendor will discuss with brokerage firms how to assess damages caused by the online trading system crashes yesterday morning, as well as preventive measures.
SET online trading for 30 brokerage members was out of order yesterday in the morning trading session due to a technical problem. The half-day disruption meant some investors lost an opportunity to place their trading orders, especially futures, which could lead to some losses.
The market jumped 19.8 points or 1.25% yesterday to close at 1,602.54 in trade worth 52.4 billion baht.
The SET provides online trading via the Streaming Pro programme operated by its subsidiary company, Settrade.com.
Settrade.com director Kirati Kosicharoen said the SET would call a meeting with securities members soon to discuss a method to prevent damaging system crashes in the future.
Mr Kirati said it was not the first time the system had been disrupted, but previous instances never took half a day to fix. The SET dealt with the crisis by asking investors to use conventional marketing staff services in ordering trades.
"Yesterday the system was out of order from 10am until 12.30pm, the first time we took such a long time to return to normal," said Mr Kirati.
Though some damage must have occurred with the crash, the market declined to discuss its compensation payment policy to affected investors, saying damage assessment will be discussed.
Streaming Pro is the most popular online trading programme with brokers, with a market share of over 50% out of 10 system vendors' programmes offering SET online trading.
"Most SET members except foreign brokers use this programme to service their clients," said Mr Kirati, adding that Settrade.com would discuss details with vendors and the SET's broker members who used the trading system yesterday.
"We cannot disclose anything now because it is a confidential agreement between the SET and brokers," he said.
"We must apologise for the inconvenience at this time, and will try our best to prevent the problem from happening again."
