Instrument Guide

SPX500 position sizing differs from forex because you're trading index points, not currency pairs, with each point worth $1 per lot. The 45-point average daily range is crucial for stop placement - using 15-25 points gives you breathing room without being stopped out by normal market noise, while 30+ point stops eat into your risk budget quickly. Worked example: On a $100k FundedNext account, 1% risk = $1000. With a 20-point stop, you calculate: $1000 ÷ (20 points × $1) = 50 lots maximum. At 2% risk ($2000), the same 20-point stop allows 100 lots. Always remember that tighter stops like 10-15 points let you trade larger size but increase your probability of being stopped out. SPX500 suits prop trading well because it trends cleanly and respects technical levels, making it easier to hit FundedNext's 8% profit target. The 5% daily loss limit means you need disciplined stop management - never risk more than 2-3% on any single trade to avoid account-ending losses. The index's liquidity during US sessions ensures tight spreads and reliable fills. Contract complexity is minimal compared to futures - you're simply trading the cash index with standard lot sizing. However, be aware of gap risk during market opens, especially Monday gaps or after major economic events. The instrument's correlation with broader market sentiment makes it predictable during trending periods but choppy during consolidation phases.
