Do circuit breakers kick in pre and post market trading?

Circuit breakers operational in pre and post market sessions?

 

Futures yes, equities no.

 

Isn’t that a big Weakness of circuit breakers on stocks? They can open below all circuit breakers.

 

It's a big advantage since circuit breakers doesn't achieve anything else than increase uncertainty.

 

If they open below then they immediately trigger a circuit breaker anyway

 

But it can open 40% down. This rendering the 7%,13%,and 20% breakers useless. As it is already 40% down.

 

No such thing as control...it's an illusion... Limiting sales does nothing...short sale ban is a complete statist solution that doesn't work.. let liquidation happen it's healthy.. bad assets need to be liquidated completely.. part of the process of building solid ground to grow on...more common sense

 

Trading halts during he regular session are triggered from the cash SP500. The halts are supposed to calm the market, the big gap downs out of limit down tells a different story.

How is a trading halt triggered for E-mini S&P 500 and S&P 500 futures and options?

Trading halts for E-mini S&P 500 and S&P 500 futures and options occur if, and only if, a NYSE Rule 80B trading halt is enacted in the cash equity market due to a 7%, 13%, or 20% downside move in the underlying S&P 500 Index relative to its previous closing price.
