It is widely used in distributed systems and in the stock market. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This device monitors calls to external services such as APIs and databases. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If it detects excessive failures or high latency, it closes the circuit.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This prevents services from becoming overloaded, thus maintaining system stability.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/valorizei.com\/wp-content\/uploads\/2025\/01\/image-3-1024x768.jpeg\" alt=\"\" class=\"wp-image-38364\"\/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">When the circuit is closed, it remains that way until service recovers. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">New requests are blocked during this time. This helps prevent further failures.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Additionally, the circuit can be in a state <em>ajar<\/em>. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This allows you to test the service recovery before returning to normal operation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Using Circuit Breaker can improve call efficiency by up to 40%. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It also increases process productivity by 55%. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>++ <a href=\"https:\/\/valorizei.com\/en\/a-psicologia-do-investidor\/\">The Psychology of Investing: How to Avoid Impulsive Decisions<\/a><\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Reduces overhead on calls to external services by up to 50% and reduces the impact of failures by 70%.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the stock market, the Circuit Breaker is crucial. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the Ibovespa falls too quickly, trading is paused. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This gives investors time to assess the market and react better.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">API failures are common in microservices systems. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, the Circuit Breaker is very important. Its implementation reduces human intervention by almost 45%. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It can also avoid up to 60% of requests to recently restored services if operating in the half-open state.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In short, the Circuit Breaker works by controlling and minimizing the impact of faults. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This ensures the stability and continuity of operations.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How the Circuit Breaker Works at B3<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">On the Brazilian Stock Exchange, B3, the Circuit Breaker is triggered at three levels of devaluation of the Ibovespa. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This mechanism is fundamental for the <em>financial market protection<\/em>. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It prevents panic and gives you time to evaluate assets rationally.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the Ibovespa falls 10% compared to the previous close, trading is halted for 30 minutes. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the index falls another 5% and reaches 15%, the market will pause again, now for one hour. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In extreme cases, a drop of 20% results in an indefinite suspension. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">B3 defines this time, ensuring that the last half hour of the market is maintained for trading.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/valorizei.com\/wp-content\/uploads\/2025\/01\/image-2-1024x768.jpeg\" alt=\"O Que \u00e9 Circuit Breaker e Como Ele Afeta Seus Investimentos?\" class=\"wp-image-38363\"\/><figcaption class=\"wp-element-caption\"><strong>Image: <a href=\"http:\/\/canva.com\">Canva<\/a><\/strong><\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><th>Drop Level (%)<\/th><th>Interruption<\/th><\/tr><tr><td>10%<\/td><td>30 minutes<\/td><\/tr><tr><td>15%<\/td><td>1 hour<\/td><\/tr><tr><td>20%<\/td><td>Undetermined<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">These <em>Circuit Breaker rules<\/em> help to moderate panic in the markets. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">They allow investors to analyze conditions without the pressure of a continued decline in stock prices. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In recent history, the system of <strong>financial market protection<\/strong> was triggered on several occasions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This happened during significant crises such as in 2008, during the subprime crisis in the US, and in 2020, during the coronavirus pandemic. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In both situations, these measures were essential to stabilize the market and avoid major collapses.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">History of Circuit Breakers on the Brazilian Stock Exchange<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Circuit breakers are rare events that show extreme moments in the market. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In Brazil, the <em>circuit breaker history<\/em> shows major financial crises. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">They also show the influence of global crises on the economy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>++ <a href=\"https:\/\/valorizei.com\/en\/pib-ipca-e-igp-m\/\">GDP, IPCA and IGP-M: What These Indicators Say About the Economy<\/a><\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Since it began, the Brazilian stock exchange has activated the circuit breaker 22 times. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In 2022, six of those interruptions were in March, due to the COVID-19 pandemic.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/valorizei.com\/wp-content\/uploads\/2025\/01\/image-1024x768.jpeg\" alt=\"\" class=\"wp-image-38361\"\/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">During the 2008 financial crisis in the US, the stock market was halted six times. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In 1999, two interruptions were due to the devaluation of the real. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These moments are <em>critical moments of B3<\/em>, showing economic volatility and uncertainty.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In 2020, the COVID-19 pandemic had a major impact.

In March 2020, the Ibovespa suffered major drops. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This happened because of the pandemic, activating the Circuit Breaker six times in eight days.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Investors with diversified portfolios and long-term strategies are less affected. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Circuit Breaker gives you time to think before selling.

They are triggered when the S&amp;P 500 index falls 7%, 13% and 20%. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These pauses help control volatility and avoid losses.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Circuit Breakers were created after major crises, such as the 1987 crash and the 2010 flash crash. They are essential for a more stable market. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Although some people criticize them, saying they can increase volatility, most believe they are important for investor confidence.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to Protect Your Investments During a Circuit Breaker<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">During a <em>Circuit Breaker<\/em>, it is crucial to remain calm. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An effective strategy is to diversify your portfolio.
