Once there is unfavorable news, a large bearish candlestick will appear, followed by a downward trend."

In the chart, a large bearish candlestick at the four-hour level appeared when there was negative news about Iran planning to block the Strait of Hormuz, which broke below the 100,000 neckline price level, establishing the beginning of a downtrend.
