Stock trading freeze
A trading curbsometimes referred to as a circuit breaker is a financial regulatory instrument that is in place to prevent stock market crashes from occurring. Since their inception, circuit breakers have been modified to prevent both speculative gains and dramatic losses within a small time stock trading freeze. As a result of being triggered, circuit breakers either stop trading for a small amount of time or close trading early in order to allow accurate information to flow amongst market makers and for institutional traders to assess their positions and make rational decisions.
These limits were put in place after Black Monday in in order to reduce market volatility and massive panic sell-offs, giving traders time to reconsider their transactions. The regulatory filing that makes circuit breakers mandatory on United States stock exchanges is Securities and Exchange Commission Rule 80B.
The most recently updated amendment of rule 80B went into effect stock trading freeze April 8,and has three tiers of thresholds that have different protocols for halting trading and closing the markets. Depending on the point drop that happens and the time of day when it happens, different actions occur automatically: Level 1 and Level 2 declines result in a minute stock trading freeze halt unless they occur after 3: A Level 3 decline results stock trading freeze trading being suspended for the remainder of the day.
Circuit breakers are also in effect on the Chicago Mercantile Exchange CME and all subsidiary exchanges where the same stock trading freeze that the NYSE has are applied to equity index futures trading. Price limits for equity index and foreign exchange futures are posted on the CME website at the close of each trading session.

This curb was fairly common, and financial television networks such as CNBC often referred to it with the term "curbs in".

The trading halt time is 10 minutes. A "circuit-breaker" mechanism began a test run on January 1, If it happens after From January 8, use of the circuit-breaker was suspended. Though the purpose behind circuit breakers is to stop trading so that traders can take time to think and digest new information, there are a lot of tested theories that show trading volume actually increases as price stock trading freeze approach a circuit breaker threshold, and trading after a halt completes lays the groundwork for even more volatile market conditions.
The Journal of Financial Markets has published work specific to the use of circuit breakers and their effects on market activity. Researchers have developed what stock trading freeze known as the "magnet effect". This theory claims that the closer market levels come to a circuit breaker threshold, the more exacerbated the situation will become stock trading freeze traders will increase volume by unloading shares out of fear that they will be stuck in their positions if markets do stop trading.
It is believed there was an institutional bias to circuit breakers, as all of the large banks, hedge fundsand even some pension funds had designated floor traders on the floor of the NYSE who can continue trading while the markets are closed to the average investor. This argument is becoming less relevant over time as the use of floor traders diminishes and the majority of trading is done by computer generated algorithms.
