难以定义我的“优势”——你们是如何找到自己的优势的？

That's a great question, I'm kind of in the same boat. Are there any particular strategies or market types where you feel like you're closer to finding an edge, or is it more about the process itself?

I'd argue that your edge is superior risk management and disciplined execution. Many strategies work, but most traders fail due to poor risk control and not sticking to their plan. Focus on that first.
