India's National Stock Exchange suffered its longest ever halt on Monday after an unidentified glitch disrupted orders and price feeds. Indonesia's Stock Exchange followed suit and was halted for 26 minutes due to a glitch with the market information distribution system.
Malfunctions and halts are a fact of life in modern stock trading, in which computers carry out the vast majority of operations. Nevertheless, market-wide suspensions are relatively rare. Singapore Exchange Ltd. shut trading early in July 2016 because of a technical malfunction, and after failing to follow through on two pledges to reopen. The Australia Stock Exchange opened late and closed early one day in September because of a glitch, its worst disruption in almost five years.
