Have you ever experienced this?

When prices are rising, you're afraid to buy high; when prices are falling, you can't bear to sell.
Staring at the market every day until your heart races,
It's not that the market is too difficult, but that people's minds are too chaotic.

Manual trading can never escape the trap of emotions.
Only quantitative strategies
can replace "emotions" with "discipline,"
allowing you to become a calm winner in the market.
