The Colombo Stock Market (CSE) will adopt a 3 tiered index based circuit breaker structure (New Circuit Breaker) which will attach to the S&P SL20 Index. The S&P Index follows 20 leading publicly traded companies on the CSE. The New Circuit Breaker was introduced by the Securities Exchange Commission (SEC) by its directive.
科伦坡证券交易所（CSE）将采用3级指数型断路器结构（新断路器），该结构将依附于标普SL20指数。标准普尔指数跟随20家领先的上市公司在科伦坡证券所上市。新断路器是由证券交易委员会（SEC） 通过其指令引入的

The New Circuit Breaker will be implemented as follows –
新断路器的实施方案如下：

First Circuit Breaker
第一个断路器

Trading to be halted for a period of 30 minutes when the S&P SL20 Index drops by 5%.
当标普SL20指数下跌5%时，交易将暂停30分钟

Second Circuit Breaker
第二个断路器

Once trading recommences following the First Circuit Breaker, trading will be halted for a further 30 minutes when the S&P SL20 Index drops a further 2.5% (ie. an aggregate drop of 7.5%).
一旦交易在第一断路器之后重新开始，当标普SL20指数进一步下跌25%（即累计下跌7.5%）时，交易将再暂停30分钟

Third Circuit Breaker
第三个断路器

Once trading recommences after the Second Circuit Breaker (ie. after the S&P SL20 Index had dropped an aggregate 7.5%), trading will be halted and the market closed for the day when the S&P SL20 Index drops a further 2.5% (ie. an aggregate 10% drop).
交易一旦在第二断路器之后重新开始（即在标普SL20指数下跌7.5%之后），在标普SL20指数进一步下跌2.5%（即累计下跌10%）时，将停止交易，当天收市。

The New Circuit Breaker is to be operational from the date the CSE reopens for trading and will remain in place until further notice.
新断路器自科伦坡证券交易所重新开放交易之日起开始运行，并将保持原状直至另行通知
