US Oil (WTI) Lot Size Calculator for FundedX

Quick Answer

USOIL has a pip value of $10 per lot, meaning each point move equals $10 per lot. With a 1% risk target and a typical 50-point stop loss (based on the 1.5-point average daily range), you'd risk $500 per lot, so position size would be 0.1 lots on a $50,000 account.

Instrument Guide
USOIL position sizing requires careful attention to its volatile nature and the $10 per point pip value. Unlike forex where you're dealing with fractional pips, oil moves in full points with significant dollar impact. The 1.5-point average daily range means price can easily swing $150 per lot in a single session, making stop loss placement crucial for survival. For stop losses, I typically use 30-50 points depending on market conditions, which translates to $300-500 risk per lot. The daily range suggests anything tighter than 25 points is likely to get stopped out by normal market noise, while stops beyond 75 points may violate proper risk management on smaller accounts. Worked example at 1% risk on a $50,000 account: Risk budget is $500. With a 50-point stop, you're risking $500 per lot (50 × $10), so position size is exactly 1.0 lot. At 2% risk ($1,000 budget), you could trade 2.0 lots with the same stop, or 1.33 lots with a 75-point stop. The key difference from other commodities is oil's sensitivity to geopolitical events and inventory data, which can gap prices beyond your stops. This makes USOIL particularly suitable for FundedX's rules - the 3% daily loss limit provides adequate buffer for unexpected moves, while the 4% max drawdown allows for multiple small losses without account termination. The 5% profit target is realistic given oil's volatility, often achievable in 1-3 trading sessions with proper position sizing.
