Instrument Guide

US30 position sizing is refreshingly simple compared to other indices - each point move equals $1 per lot, eliminating the contract multiplier confusion you get with ES or NQ. The 350-point average daily range means this instrument moves aggressively, often hitting 200-400 point swings intraday, which directly impacts your stop loss placement and position size calculations. For stop losses, I typically see successful US30 traders using 50-150 point stops depending on strategy. Scalpers might use 30-50 points, while swing traders often need 100-200 points to avoid getting shaken out by normal volatility. The key is respecting that 350-point daily range - anything under 50 points is fighting the instrument's natural movement. Worked example: On a $50,000 account risking 1% ($500), with a 100-point stop loss, you'd trade 5 lots maximum ($500 risk ÷ $100 stop = 5 lots). At 2% risk ($1,000), you could trade 10 lots with the same stop. If you tighten to a 50-point stop, those numbers double to 10 lots (1%) or 20 lots (2%). US30 suits prop trading well due to its liquidity and clear technicals, but the wide spreads during news events can eat into profits quickly. The instrument's volatility means you can hit profit targets fast, but it also means getting stopped out frequently if you're undersized for the daily range. Focus on the daily ATR when setting stops rather than arbitrary round numbers - US30 doesn't care about your comfort zone, only its statistical movement patterns.
