Actualizado Volatility Stop Selector
The Volatility Stop Selector is a comprehensive trend-following tool designed to automatically identify the optimal volatility stop strategy. It features adjustable parameters and an integrated backtester that delivers institutional-grade insights into the recommended strategy. The model continuously adapts to new data in real time by evaluating multiple volatility length and factor combinations, determining the best-performing configuration, and presenting the backtest results in a clear, color-coded table that benchmarks performance against the buy-and-hold strategy.
At its core, the model systematically backtests a wide range of volatility stop combinations to identify the configuration that maximizes the selected optimization metric. Users can choose to optimize for absolute returns or risk-adjusted returns using metrics such as the Sharpe, Sortino, Martin, or Calmar ratios. The Martin ratio is particularly well suited for volatility-based risk management strategies, as it evaluates returns relative to the Ulcer Index, capturing both the depth and duration of drawdowns and therefore favoring smoother equity curves. Alternatively, users can enable manual optimization to test custom volatility length and factor settings and view the corresponding backtest results. The label displays the Compounded Annual Growth Rate (CAGR) of the strategy, with the buy-and-hold CAGR in parentheses for comparison. The table presents the backtest results based on the volatility length and factor displayed at the top:
This indicator is designed with flexibility in mind, enabling users to specify the start date of the backtesting period, the preferred volatility type, and the price source. Supported volatility types include the Average True Range (ATR), Standard Deviation (SD), and Mean Absolute Deviation (MAD). Supported price sources include Close, Heikin Ashi, HL2, HLC3, and OHLC4. To minimize overfitting, users can define constraints such as a minimum and maximum number of trades per year, as well as an optional optimization margin that prioritizes more robust combinations by requiring more reactive combinations to exceed this threshold. The table follows an intuitive color-coded logic that enables quick performance comparison against buy-and-hold (B&H):
In summary, the Volatility Stop Selector is a powerful tool designed to help investors make data-driven decisions when selecting volatility-based trend-following strategies. By optimizing for risk-adjusted returns, investors can identify the best configurations using institutional-grade metrics. While results are based on the selected historical period, users should be mindful of overfitting, as past results may not persist under future market conditions. Since the model continuously recalibrates to incorporate new data, the recommended length and factor may evolve over time.

The table presents the backtest results based on the volatility length and factor displayed at the top:
- Sharpe = CAGR per unit of standard deviation.
- Sortino = CAGR per unit of downside deviation.
- Calmar = CAGR relative to maximum drawdown.
- Max DD = Largest peak-to-trough decline in value.
- Beta (β) = Return sensitivity relative to buy-and-hold.
- Alpha (α) = Excess annualized risk-adjusted returns.
- Win Rate = Ratio of profitable trades to total trades.
- Profit Factor = Total gross profit per unit of losses.
- Expectancy = Average expected return per trade.
- Trades/Year = Average number of trades per year.

- Max DD = Green indicates better than B&H, while red indicates worse.
- Beta (β) = Green indicates better than B&H, while red indicates worse.
- Alpha (α) = Green indicates above 0%, while red indicates below 0%.
- Win Rate = Green indicates above 50%, while red indicates below 50%.
- Profit Factor = Green indicates above 2, while red indicates below 1.
