Risk Guide

On Top One Trader's $25k account, you have exactly $1,000 daily loss protection before breach. At 1% risk per trade ($250), you can survive 4 consecutive losses. At 2% risk ($500), just 2 losses wipe your daily limit. This is the mathematical reality that separates successful prop traders from those who blow accounts. The danger scenario: Opening multiple 2% positions simultaneously. If you're holding 3 trades at $500 risk each and news hits, you're looking at $1,500 potential loss – instantly breaching both daily limit and approaching your $1,750 max drawdown. Always calculate combined exposure across all open positions. Position sizing math for popular pairs: EURUSD with 30-pip stop at 1% risk = 0.83 lots ($250 ÷ 30 pips). GBPUSD 40-pip stop = 0.625 lots ($250 ÷ 40 pips). For indices, NAS100 with 20-point stop = 1.25 lots ($250 ÷ $20 per point). Gold 10-pip stop = 2.5 lots ($250 ÷ $10 per pip). Phase 1 requires $2,500 profit (10%) with max 15% daily consistency – meaning no single day can exceed $375 profit. Phase 2 drops to $1,250 target (5%) but maintains all risk limits. Many traders increase size after hitting Phase 1, then breach daily loss limits in Phase 2. Your $1,000 daily loss limit never changes. The 5-day minimum trading requirement forces activity, but don't let it push you into overtrading. At 1% risk, you need disciplined entries since you're limited to 4 losing trades daily. Smart money uses 0.5-1% risk during drawdown periods and scales up only when equity curve is ascending. Your $86 challenge cost should remind you this isn't gambling – it's business mathematics.
