มือใหม่ครับ มีคำถามเรื่องการกำหนดขนาด Position สำหรับบัญชีเล็ก

Completely understand the dilemma. For small accounts, the percentage-based risk can sometimes lead to very small position sizes, making commission costs a factor. Have you looked into micro-lots for forex or smaller share sizes/fractional shares for equities if your broker offers them?

The fee issue is certainly a consideration for smaller accounts. Have you looked into brokers with lower commissions or those offering fractional shares, as that might help with the 'too little' end of your concern?
