The new limits, effective January 6, will ensure stock prices do not go up or down beyond a level during a session.
Circuit filter mechanism is used by stock exchanges to keep excessive volatility in check. It is the maximum fluctuation that is allowed during trading, which gets suspended if the permissible limit is hit in either direction.
In a circular, the exchange said that it has set a circuit limit of 10 per cent for Khaitan Electricals.
A limit of 5 per cent has also been set for Ruby Traders & Exporters.
The circuit filters have been changed from their existing levels in the eight scrips with effect from January 6, as per the circular.
