The market wide circuit breakers would be triggered by movement of either SENSEX or the NSE S&P CNX Nifty whichever is breached earlier.
In case of a 10% movement of either of these indices, there would be a 1-hour market halt if the movement takes place before 1 p.m. In case the movement takes place at or after 1 p.m. but before 2.30 p.m. there will be a trading halt for ½ hour. In case the movement takes place at or after 2.30 p.m. there will be no trading halt at the 10% level and the market will continue trading.
In case of a 15% movement of either index, there will be a 2-hour market halt if the movement takes place before 1 p.m. If the 15% trigger is reached on or after 1 p.m. but before 2 p.m., there will be a 1 hour halt. If the 15% trigger is reached on or after 2 p.m. the trading will halt for the remainder of the day.
In case of a 20% movement of the index, the trading will be halted for the remainder of the day.
