มือใหม่ครับ - ทุกคนมีวิธีจัดการขนาด Position อย่างไรเมื่อความมั่นใจไม่เท่ากัน?

This is a great question! I've been wondering the same thing. Do you ever find that when you do size up on a 'high conviction' trade, it tends to go against you more often, almost like a psychological jinx?

That's a great question, and it's something many experienced traders grapple with too. While sticking to a fixed percentage per trade simplifies risk management, varying position size based on conviction can lead to larger gains on high-probability setups, but it also opens the door to emotional biases if not applied with strict discipline.

It's a common dilemma. While varying position size based on conviction can work, it's also where many traders introduce emotional bias. Have you considered using a multi-factor system to quantify your trade quality, rather than just a 'feeling'?
