🧠 Guidance for Small Accounts
Capital Preservation first
• Accounts < $10k → stay ≤ 1 % risk (often 0.5–0.75 %)
• Never use Full Kelly live – drawdowns of 40–60 %+ are normal
• Half-Kelly or Quarter-Kelly + 1 % rule is the sweet spot for most retail traders
Growing fast safely
• Positive expectancy + compounding is the only reliable way
• Fixed Ratio (Ryan Jones) style ramping can be added later once you have consistency
• Focus on process, not daily P&L targets
