มือใหม่ครับ มีคำถามเกี่ยวกับการกำหนดขนาด Position เมื่อความผันผวนต่างกัน

Welcome! I'm pretty new too, but I've been wrestling with the same question. Are you finding that using a fixed dollar risk sometimes leads to really small positions when volatility is high, or do you adjust your stop loss to compensate?

Welcome to the thunderdome! I've found that trying to perfectly calibrate position size to every market twitch is a fool's errand. Eventually, you just resign yourself to the fact that sometimes the market wants a bigger slice of your capital pie, and other times it's surprisingly polite.
