Executive Definition & Core Answer

Risk-adjusted return ratios—including the Sharpe Ratio, Sortino Ratio, Calmar Ratio, and System Quality Number (SQN)—quantify the excess return generated by a trading system per unit of volatility or downside risk. In paper trading evaluation, these metrics distinguish between genuine institutional alpha and reckless leverage that masks catastrophic tail risk.

This analysis is part of the SlateTick paper trading platform and trade execution journal, designed to calibrate execution discipline, risk modeling, and multi-asset simulation across Equities, Forex, and Crypto without risking live capital.

Structured Trade Logging Protocol for Sortino Ratio Calculation

Step-by-step institutional rules and quantitative procedure

1 Periodic Return Compilation

Establish calibrated baseline parameters and execution thesis for Sortino Ratio Calculation. Tabulate daily and weekly percentage returns of the simulated account over at least 60 trading days.

2 Benchmark Benchmark Subtraction

Subtract the risk-free rate (e.g. 4.5% annual cash yield) to isolate excess return.

3 Volatility Dispersion Calculation

Compute standard deviation of all returns (Sharpe) or downside deviation only (Sortino).

4 Annualized Ratio Formulation

Scale ratio by sqrt(252) for daily returns to standardize annual risk-adjusted return.

5 System Comparison Audit

Conduct weekly cohort audits and system reviews for Sortino Ratio Calculation. Benchmark paper trading Sharpe/Sortino against index benchmarks (SPY 1.0-1.2).

Trade Journal Cohort Sample: Apple Inc. (AAPL)

Precise formula and quantitative position-sizing model

Formulation & Proof $100k Virtual Capital Sizing
Simulated Account: $100,000 virtual balance. Baseline Risk (1.0R): $1,000. Trade Model: Sortino Ratio Calculation on Apple Inc. (AAPL). Simulated Account: $100,000 virtual capital. Audit Horizon: 120 Days. AAPL Strategy Annualized Return: 26.4% Risk-Free Benchmark Yield: 4.5% Annualized Volatility (StDev σ): 8.8% Annualized Downside Deviation (σd): 4.1% Maximum Historical Drawdown: 6.8% Risk-Adjusted Performance Ratios: - Sharpe Ratio = (26.4% - 4.5%) / 8.8% = 2.49 (Exceptional risk-adjusted return > 2.0) - Sortino Ratio = (26.4% - 4.5%) / 4.1% = 5.34 (Downside volatility heavily penalized) - Calmar Ratio = Annual Return (26.4%) / Max Drawdown (6.8%) = 3.88 Journal Conclusion: System achieves top-quartile capital efficiency with minimal downside turbulence.

By calculating position size strictly based on the distance between your entry price and technical invalidation level, your risk remains fixed at 1.0R ($1,000) regardless of the asset's nominal price.

Frequently Asked Questions

Essential inquiries on execution, verification, and journal analytics

Q1: Why is Sortino Ratio Calculation critical for simulated paper trading?

Sharpe penalizes upside volatility (large winning trades) equally to downside drops. Sortino only penalizes negative returns, providing a clearer gauge of downside risk.

Q2: What is considered a good Sharpe Ratio in paper trading?

A Sharpe Ratio above 1.5 is strong, and above 2.0 is institutional grade. In simulation, aim for > 2.0 to account for real-world slippage decay.

Q3: How does SlateTick support Sortino Ratio Calculation?

SlateTick automatically compiles your daily equity curve and generates real-time Sharpe, Sortino, and Calmar metrics in your performance analytics tab.
