สับสนกับ ATR ที่แท้จริงสำหรับการกำหนดขนาดตำแหน่งในกราฟรายวัน

You're definitely not overthinking it; that's the core of translating volatility into a practical position size. The dollar ATR tells you the typical daily range, and you use that, along with your risk per trade (e.g., 1% of your account), to calculate how many shares you can afford for that move. Your broker's percentage stop is usually based on price, not volatility, which is a key distinction.

You're not overthinking. The ATR value is your volatility measure. To size, you'd use that dollar value, your desired risk per trade (e.g., 1% of account), and then calculate shares from there. Your broker's calculator likely assumes a fixed dollar stop, not one based on ATR.

This is exactly what I'm struggling with too! I get the concept of using ATR to define a stop, but then turning that into an actual share count that respects a risk percentage is where I get lost. Are most people doing manual calculations every time, or is there a tool I'm missing?
