⚠️ Transparency & Limitations

This calculator implements the exact formulas from our research paper. You can verify every calculation. Important: These models are theoretical and have NOT been validated across all market regimes. Use for educational purposes and independent verification only. Not financial advice.

📊 Distance to Ruin (DR)

Measures how many standard deviations separate you from ruin

Formula Used:

DR = [ln(B/L) + (μ - σ²/2)T] / (σ√T)

Where:
• B = Current Bankroll
• L = Loss Threshold
• μ = Expected Return
• σ = Volatility
• T = Time Horizon

🌊 Trading Reynolds Number

Determines if your strategy is laminar (smooth) or turbulent (chaotic)

Formula Used:

Re = (σ × L²) / μ

Interpretation:
• Re < 1: Laminar (smooth, sustainable)
• 1 ≤ Re ≤ 10: Transitional (monitor closely)
• Re > 10: Turbulent (high risk, psychological stress)

🎯 Kelly Criterion

Optimal position sizing for maximum long-term growth

Formula Used:

L* = (μ - c) / (2 × c)
Fractional Kelly = L* × fraction

Where:
• μ = Expected return
• c = Transaction cost
• fraction = Risk reduction multiplier

⚙️ LPE: Required Bots Calculator

How many independent strategies do you need?

LPE Approach:

1. Target drift = k × benchmark
2. Solve quadratic for leverage L
3. Check DR and Reynolds constraints
4. Calculate minimum X bots needed
5. Portfolio drift = X × μ × L
6. Portfolio volatility = √X × σ × L

📚 Quick Reference: Interpretation Guidelines

Distance to Ruin (DR)

DR < 2: High ruin risk - reduce leverage or improve strategy
2 ≤ DR < 4: Moderate risk - acceptable but monitor closely
DR ≥ 4: Low ruin risk - comfortable trading zone
DR ≥ 6: Very safe - excellent risk buffer

Reynolds Number (Re)

Re < 1: Laminar flow - smooth equity curve, sustainable
1 ≤ Re ≤ 10: Transitional - choppy but manageable
Re > 10: Turbulent - high stress, prone to failure
Target: Keep Re below 1 for comfort

Adjusted SQN (aSQN)

< 0.5: Weak - likely noise
0.5-0.9: Marginal - needs improvement
1.0-1.4: Good - deployable with caution
1.5-1.9: Very good - scalable
≥ 2.0: Excellent - flagship quality

🔓 Open Source Philosophy

All formulas are displayed transparently. You can inspect the JavaScript source code to verify every calculation. We encourage independent verification and welcome feedback.
