## Interactive Quantitative Tools & Calculators (`/tools`)

### Terminal margin Value-at-Risk (VaR) & Expected Shortfall calculator
- URL: https://terminalledgerdesk.com/calculators/terminal-margin-var-es-calculator
- Summary: Calculate pre-trade terminal margin VaR and tail Expected Shortfall at 95% and 99% confidence.
- Methodology: Electronic trading terminals and FIX pre-trade risk gateways enforce real-time margin limits using parametric Value-at-Risk (VaR) and Expected Shortfall (ES). This benchmark tool calculates book-level VaR and tail ES across custom liquidation horizons.
- Formulas: σ_h = σ_annual × √(Horizon_Days ÷ 252) | VaR_α = Notional × z_α × σ_h | ES_α = Notional × σ_h × φ(z_α) ÷ (1 − α)
- Model Assumptions:
  - Scales daily volatility by √T over 252 trading sessions per year.
- Calculator FAQs:
  - **Q: Why do institutional risk gateways monitor Expected Shortfall alongside VaR?**
    A: VaR only specifies the threshold of a 99% tail event, whereas Expected Shortfall quantifies the average equity depletion during a gap event that pierces the stop-out level.

### Algorithmic EA & FIX strategy Kelly sizing calculator
- URL: https://terminalledgerdesk.com/calculators/algorithmic-kelly-allocation-calculator
- Summary: Compute Full, Half and Quarter Kelly lot sizing and geometric growth for automated trading systems.
- Methodology: Automated Expert Advisors (EAs), cTrader cBots, and FIX execution strategies require disciplined fractional sizing to survive execution slippage and regime shifts. This calculator derives Full, Half, and Quarter Kelly allocations from empirical win rates and reward-to-risk ratios.
- Formulas: Kelly f* = Win_Prob − (1 − Win_Prob) ÷ Payoff_Ratio | Geometric growth g(f) = p × ln(1 + f × b) + (1 − p) × ln(1 − f)
- Model Assumptions:
  - Assumes stationary strategy edge net of terminal commission and slippage.
- Calculator FAQs:
  - **Q: Why should automated terminals cap sizing at Quarter or Half Kelly?**
    A: Live bridge latency and liquidity gaps reduce realized payoff ratios compared to backtests; trading Half Kelly retains 75% of theoretical log growth while cutting drawdown volatility in half.
