Risk Guide
FundedX's $800k account gives you substantial buying power but demands strict risk management around the $24,000 daily loss limit. At 1% risk per trade ($8,000), you can absorb exactly 3 consecutive losses before hitting your daily limit. At 2% risk ($16,000), you're down to just 1.5 losing trades - meaning two losses puts you dangerously close to breach territory. The math is unforgiving at this account size.
For position sizing, use this formula: Risk Amount ÷ (Stop Loss in Pips × Pip Value) = Lot Size. On EURUSD where each pip equals $10 per lot, a 50-pip stop at 1% risk gives you 1.6 lots ($8,000 ÷ $500). For GBPJPY at $9.12 per pip, that same 50-pip stop allows 1.75 lots. Gold traders with a $20 stop can trade 4 lots at 1% risk ($8,000 ÷ $2,000).
The real danger with FundedX's large account is overconfidence leading to oversized positions. Many traders see $800k and think they can trade massive size, forgetting that $24,000 disappears quickly with poor risk management. A seemingly conservative 0.5% risk still means $4,000 per trade - lose 6 trades and you're done for the day.
Unlike firms with different challenge and funded rules, FundedX keeps everything consistent. Your 3% daily loss limit and 4% max drawdown ($32,000) remain identical from challenge through funded phases. This means no adjustment period - the same position sizing discipline that gets you funded keeps you funded. Focus on the $40,000 profit target (5%) to pass, but remember that with no minimum trading days, you can take your time and avoid the rushed trading that kills accounts this size.
