คำถามเกี่ยวกับการกำหนดขนาด Position หลังจากขาดทุนเล็กน้อยหลายครั้ง

I'd argue against reducing your size further unless your overall strategy has fundamentally changed. If the setups are still good, you're just experiencing normal variance. Deviating from your fixed percentage risk every time you hit a rough patch can lead to inconsistent results and makes it harder to assess your true edge over time.

It's totally normal to feel that hesitation. Sticking to your defined risk is crucial, but if a couple of losses are really messing with your psychology, there's no harm in slightly reducing your position size for a trade or two until your confidence returns. Just be sure to go back to your original plan when you're feeling better.
