US Oil (WTI) Lot Size Calculator for FundedNext

Instrument Guide

Oil position sizing requires understanding its explosive volatility compared to forex pairs. With a 1.5-point average daily range and $10 per pip, a full lot can swing $1,500 daily - that's serious money that demands respect. Your stop losses need to account for oil's tendency to spike and reverse quickly, especially around inventory reports and geopolitical events. I typically set stops at 30-50 points to avoid getting whipsawed by normal market noise, though breakout trades might warrant tighter stops. Here's the math that matters: on a $100k FundedNext account risking 1% ($1,000), a 50-point stop allows 0.2 lots maximum (50 points × $10 × 0.2 lots = $1,000 risk). Double that risk to 2% and you can trade 0.4 lots with the same stop. The beauty of oil for prop trading is its trending nature - when it moves, it really moves, making those 8% profit targets very achievable. However, that same volatility makes it dangerous for over-leveraged positions. Oil respects technical levels better than most instruments, so your position sizing should align with clear support/resistance rather than arbitrary risk percentages. Given FundedNext's 5% daily loss limit, never risk more than 2-3% on any single oil trade - the instrument can gap against you faster than you can react. The overnight and weekend gap risk is real with oil, so size accordingly if holding positions through sessions. This instrument rewards patient, well-sized positions over rapid-fire scalping approaches.
