In the market, shorting and going long cannot rely on feelings and common sense, but rather on solid technical analysis.
It shouldn't be based on a personal feeling that the market will rise or fall, or what others say about rising or falling.
Instead, it should be about identifying signals of rising or falling through technical indicators.
Once identified, you can try small positions; if your view is validated, then you can gradually increase your position.
At the same time, maintain correct position management, precise point judgment, and calm thinking. Generally, it is still possible to achieve some results.
