การจัดการธง AML สำหรับการไหลของสกุลเงินแปลกใหม่

That's a really good point. The traditional AML models often struggle with low-volume, high-volatility pairs where 'normal' is already quite varied. It definitely requires a more nuanced approach than just absolute value thresholds.

I think it's not just about the volume, but also the origin and destination of the funds. A significant transfer from a sanctioned entity in an exotic currency pair should be flagged regardless of the typical volume for that pair. The stablecoin aspect just adds another layer of complexity.

You're right, percentage deviation is tricky. Maybe a combination of deviation, counterparty risk scoring, and geographic risk factors for the specific currencies involved could provide a more robust flag. It's a tough nut to crack for sure.
