Risk Guide
With FundedX's $400k account and $12,000 daily loss limit, you can take exactly 3 losing trades at 1% risk ($4,000 each) before hitting the limit. At 2% risk ($8,000 per trade), just one loss plus a second trade puts you dangerously close to breach - two full losses would mean $16,000, exceeding your daily limit by $4,000. The critical danger scenario for this account size is revenge trading after a $8,000+ loss. Many traders think they can 'make it back' with a larger position, but even a 1% recovery trade risks another $4,000, potentially pushing total daily losses to $12,000+ and ending your challenge. For position sizing math: On EURUSD with a 30-pip stop, 1% risk ($4,000) allows roughly 4 standard lots. For GBPJPY with a 50-pip stop, you can trade about 2.4 standard lots. On XAUUSD with a $20 stop, approximately 20 standard lots fits within 1% risk. Always calculate exact position sizes based on your stop loss distance - never guess. Since FundedX runs a single-phase challenge, your risk management doesn't change between phases. The same $12,000 daily loss limit and $16,000 max drawdown apply throughout. The key difference is that once funded, you're trading with real capital where consistency becomes crucial for long-term success. Most successful traders on this account size stick to 0.5-1% risk per trade, allowing for multiple consecutive losses without account damage. The $20,000 profit target (5%) is achievable with 20 trades risking 1% each with a 1:1 risk-reward ratio, assuming 65% win rate. Focus on protecting the downside - the $16,000 max drawdown means just 4 consecutive 1% losses ($16,000 total) could end your challenge even without daily limit breaches.
