One of the trading rules: Follow the major trend and go against the minor trend

Following the major trend and going against the minor trend is a trading strategy that involves opening positions in the direction of the larger timeframe trend while entering during small corrections or rebounds within the larger trend.

Simply put, for example, if the major trend is upward (big trend), only take long positions; when the price experiences a short-term decline for a minor correction (small trend), buy on dips against the trend, which not only aligns with the long-term upward direction but also allows for entry at a better price.
