มือใหม่ครับ ขอคำถามสั้นๆ เกี่ยวกับการกำหนดขนาดสถานะสำหรับฟิวเจอร์ส

For futures, I size based on the dollar value of my stop-loss for each trade, scaled by my account size. It's essentially the same principle as options, just need to account for the contract multipliers.

Welcome! That's a great point about the leverage and daily settlement making options/spot crypto sizing rules feel less applicable. For futures, I tend to combine a fixed percentage of my account per trade with a 'point value' understanding of the contract, which helps in adjusting the number of contracts based on my stop loss.

Welcome to the deep end! You're right, options and spot crypto are like finger painting compared to the adult colouring book of futures. Your old risk rules are likely wearing too-small shoes now. Many stick to a strict R-multiple per trade, but don't forget to factor in the overnight session's ability to humble even the most confident among us.
