I just closed a long position with a 5% stop loss last night. It's a bit unfortunate. But this is also a lesson fee. I plan to add another 10U tomorrow to bring the account back to 10U, and then start over.

This is my first day starting with 10U. My trading data looks like this — a total of 32 positions, with 25 profitable and 7 losing. It seems like a good win rate, but the account actually lost 10%. The reason is simple: the risk-reward ratio was not well designed. The profits were small, but the losses were larger, so in the end, it was still negative.

This lesson must be remembered — trading is not won by win rate, but by risk-reward ratio.
