💡 Institutional Position Sizing Rules

• Banks risk 0.5-2% per position — never more than 5% total portfolio risk
• Prop firms typically allow 1-2% per trade with 5% daily max drawdown
• Scale position size based on conviction: High = 2%, Normal = 1%, Low = 0.5%
• Always adjust for volatility — reduce size during news events (NFP, FOMC)
• Institutional traders use ATR-based stops, not fixed pip amounts
