Instrument Guide

US30 position sizing is refreshingly simple compared to forex - each point move equals $1 per lot, no currency conversions needed. This 1:1 relationship makes risk calculations crystal clear, but the instrument's volatility demands careful attention to position sizing. With an average daily range of 350 points, US30 moves significantly more than major forex pairs. This volatility creates both opportunity and risk. A typical swing trade might use a 100-150 point stop loss, while day traders often work with 30-80 point stops depending on their strategy and timeframe. For a worked example on a $100,000 account: risking 1% ($1,000) with a 100-point stop means you can trade 10 lots ($1,000 ÷ 100 points ÷ $1). Double the risk to 2% and you're looking at 20 lots. With a tighter 50-point stop, you could size up to 20 lots at 1% risk or 40 lots at 2%. The instrument's high liquidity during US market hours makes it excellent for prop trading, with tight spreads and reliable fills. However, the substantial point values mean position sizes stay relatively modest - you're rarely trading hundreds of lots like you might with EURUSD. Be particularly cautious during major economic announcements when US30 can gap 100+ points instantly. The 350-point average daily range isn't evenly distributed - you might see 200 points in the first hour then sideways action, or steady trends throughout the session. This volatility pattern makes US30 ideal for traders who can dedicate focused screen time rather than set-and-forget approaches.
