[1]The Bombay Stock Exchange (BSE) on Thursday said trading would halt for the day if the benchmark Sensex moves up or down 20 per cent, or 3,775 points, in a single day for the July-September quarter.
According to a statement by BSE, market circuit breakers would be triggered at three stages of the index movement either way at 10 per cent, 15 per cent and 20 per cent.
It further said that market circuit breakers will come into play on movements of BSE Sensex or the NSE S&P CNX Nifty, whichever is breached earlier.
In case of a 10 per cent or 1,875-point movement either way before 1p.m., there would be a one-hour market halt. If it is after 1p.m. but before 2.30p.m., the halt is for half an hour. There will be no trading halt, if Sensex or Nifty moves 10 per cent up or down at or after 2.30p.m.
In case of a 15 per cent movement or 2,825 points in index before 1 pm, there will be a two-hour market halt. If the 15 per cent trigger level is reached on or after 1pm but before 2pm, there will be a halt of an hour. If this trigger is reached on or after 2pm, the trading will be halted for the remainder of the day.
Further, in case of a 20 per cent, or 3,775-point, movement of the index, the trading will be halted for the remainder of the day, it said.
The circuit breaker brings about a coordinated trading halt in all equity and equity derivative markets nationwide.
