US30 (Dow Jones) Lot Size Calculator for The Funded Trader

Quick Answer

Firm Rules Summary

Instrument Guide

US30 position sizing is refreshingly simple compared to other indices - each point move equals $1 per lot, eliminating complex contract value calculations. With an average daily range of 350 points, this index offers substantial movement that requires careful stop loss consideration. Unlike ES or NQ where you're dealing with varying contract sizes, US30's 1:1 point-to-dollar ratio makes mental math effortless during live trading. The 350-point daily range means stops under 50 points are often noise, while stops over 200 points eat too much risk capital. Sweet spot stops typically range from 75-150 points depending on your timeframe and strategy. Worked example at 1% risk ($1000 on $100k account): With a 100-point stop, divide $1000 by $100 (100 points × $1) = 10 lots. At 2% risk ($2000): same 100-point stop gives you 20 lots. Notice how the clean math lets you quickly adjust position size as volatility changes. For prop trading, US30 fits well with most challenge parameters. The instrument's liquidity ensures tight spreads during major sessions, and the predictable contract specification reduces execution surprises. However, the substantial point movements mean smaller accounts need wider stops or smaller positions - you can't scalp 20-point moves effectively when daily ranges hit 350+ points. The key advantage here is transparency: no hidden multipliers or complex contract specs. When US30 moves 100 points against your 10-lot position, you know immediately it's a $1000 loss. This clarity is invaluable during high-stress trading moments when quick position adjustments matter most.
