Trading is not about speed, but stability. My current principle: if the market is outside my trading range, I never act impulsively; when it enters the range, I only do things within the rules.

I use a system to counteract emotions: look for signals to enter without relying on feelings, always set stop-losses for each trade, take profits in stages, and transfer to cold wallets.
To cultivate a stable mindset, there are three points: appropriately stay away from the market to see the trend clearly; maintain long-term thinking, avoid greed for short-term quick profits; only trade with spare money, not affecting daily life.
No need to watch the market constantly; by sticking to rules and keeping a steady mindset, you can actually make money.
