Strategy profile
The evaluated algorithm represents the core, top-ranked strategy for DAL (Delta Air Lines) within the DevioLab quantitative database, holding a DevioLab score of 83.06 and ranking first among tested logic models for this symbol. Operating on a 15-minute candle interval, the system functions as decision logic suitable for automated trading bots and trading agents seeking systematic execution in equity markets. Over a dataset spanning from September 16, 2019, to September 22, 2026—representing approximately 7.02 years of simulated historical market behavior—the strategy generated 108 completed trade signals. Out of these 108 closed positions, 92 were profitable and 16 resulted in losses, establishing a historical win rate of 85.19 percent. The aggregate sum of closed trade returns over the total backtest period reached 12,342.40 percent, reflecting substantial compounding potential when expressed through annualized analytical benchmarks. Rather than acting as a high-frequency trading algorithm, the system operates as a selective swing model that filters out market noise on shorter timeframes to capture macro-directional moves in the underlying stock.
Trading rhythm and position duration
Analyzing the temporal parameters reveals a calm, deliberate trading pace that contrasts with typical intraday 15-minute algorithms. The strategy records an average holding time of 194.31 hours (approximately 8.1 days) and a median holding duration of 143.13 hours (roughly 6.0 days). This multi-day holding window confirms that while 15-minute price bars provide the signal execution grid, the strategy's underlying positions are structured to capture intermediate equity swings lasting one to two weeks. On an annual basis, the algorithm averages 15.39 trades per year, which translates to approximately 1.59 completed trades per active month. The pace between trade exits is equally spacious, with an average interval of 23.68 days and a median interval of 20.00 days between closed positions. For deployment in automated trading systems or trading robots, this low-turnover cadence implies long periods of cash preservation interrupted by highly targeted market entries, avoiding over-trading and reducing exposure to continuous market friction.
Quality of historical results
The financial payoff structure displays exceptional balance and statistical stability across its trade distribution. The strategy delivers an average trade return of 4.95 percent and a median trade return of 3.94 percent. The close proximity between the mean and median indicates that performance is not driven by extreme tail events or distorted by isolated outliers. The single best historical trade yielded 31.79 percent, whereas the single worst trade registered a loss of 10.09 percent. A central metric demonstrating performance quality is the profit factor of 5.00, meaning gross gains exceeded gross losses by a five-to-one ratio. Furthermore, the top three winning trades account for only 12.35 percent of aggregate gross profits. This remarkably low concentration figure proves that profitability is broadly distributed across the 92 winning trades rather than depending on a few lucky windfalls. The algorithm demonstrates high expectancy per trade execution, fulfilling a critical requirement for robust automated trading logic.
Risk, drawdown and losing behavior
Downside risk characteristics within the backtest reveal effective capital protection mechanics. The maximum peak-to-trough drawdown recorded across the entire 7.02-year backtest was 10.09 percent, matching the exact figure of the worst individual trade loss (-10.09 percent). This numerical alignment indicates that drawdowns were primary reflections of single losing events rather than extended compounding loss series. The algorithm recorded a longest losing streak of just 2 consecutive trades, compared to a longest winning streak of 19 consecutive profitable trades. An 85.19 percent win rate paired with a tight 2-trade maximum losing streak creates an equity curve with minimal psychological friction and high statistical resilience. For quantitative trading agents executing systematic orders, limiting drawdown to approximately 10 percent over a multi-year horizon provided a stable foundation for capital preservation during turbulent market regimes.
Behavior through time and yearly stability
Examining performance across individual calendar years demonstrates multi-year regime adaptability. In late 2019, the strategy executed 2 trades with a 50.00 percent win rate and a modest sum return of 0.61 percent. In 2020, during period volatility, trade frequency expanded to 21 completed trades, yielding a 95.24 percent win rate (20 wins, 1 loss) and a cumulative trade sum of 193.16 percent. Performance remained solid through subsequent years: 2021 generated 16 trades with an 81.25 percent win rate (+67.21 percent sum); 2022 produced 14 trades with a 78.57 percent win rate (+70.70 percent sum); and 2023 delivered 15 trades with an 80.00 percent win rate (+30.54 percent sum). The year 2024 achieved a flawless 100.00 percent win rate across 11 completed trades (+39.92 percent sum). Activity in 2025 expanded to 19 trades with an 84.21 percent win rate (+95.88 percent sum), while the partial data for 2026 shows 10 trades with an 80.00 percent win rate (+36.51 percent sum). The strategy consistently produced positive total returns in every single full calendar year analyzed.
Recent period since 2024-06-01 versus full history
Evaluating recent behavior from June 1, 2024, onward offers critical insight into contemporary model efficacy. In this recent window, the strategy executed 36 completed trades, accumulating a combined sum return of 156.71 percent. Comparing this activity to the total historical dataset reveals an increase in signal density: 36 of the strategy's 108 total trades (33.3 percent) occurred within this recent sub-period. The strong performance generated during this timeframe confirms that the strategy's trade logic has maintained its edge in recent market conditions rather than relying solely on older historical data. For quantitative analysts evaluating trading bots for live implementation, this recent multi-trade performance cluster provides strong empirical confirmation that the algorithm's core structural mechanics remain well-aligned with contemporary price dynamics in DAL.
Strengths and limitations
The primary statistical strengths of this algorithm include an exceptionally high win rate of 85.19 percent, an outstanding profit factor of 5.00, a minimal top-three profit concentration of 12.35 percent, and a tightly controlled historical drawdown capped at 10.09 percent. These traits reflect a stable statistical edge that generates consistent returns across varied yearly market cycles. Conversely, material analytical limitations exist. The strategy's average holding period of 6 to 8 days exposes open positions to overnight gap risk and weekend news events inherent to traditional stock exchange schedules. Additionally, the selective nature of the system—averaging roughly 15 trades per year—requires strict operational patience, as prolonged neutral periods occur between trade entries. Quantitative automated trading agents must be calibrated to accommodate these extended holding times without prematurely exiting valid algorithmic signals.
DevioLab analytical conclusion
With a top ranking for its target ticker DAL and a DevioLab quantitative score of 83.06, this 15-minute strategy presents a compelling historical model for automated equity trading. Its architecture demonstrates that high signal accuracy can be successfully combined with disciplined drawdown control without relying on high-frequency churn or unhealthily concentrated outlier trades. The empirical data highlights a system that excels at harvesting swing trends while maintaining strong downside boundaries. For quantitative developers and algorithmic traders deploying automated trading robots or decision logic, this strategy offers a robust historical blueprint built on high win expectancy, low profit concentration, and multi-year structural stability across varying market environments.
Data scope and methodology
The statistics cited in this article are derived strictly from simulated backtested closed trades for the DAL strategy over the historical dataset spanning September 16, 2019, to September 22, 2026. All performance calculations reflect discrete closed trade return percentages on a per-trade basis without compounding dynamic leverage, accounting for order slip, or deducting broker commissions and financing fees. The recent evaluation window specifically isolates completed positions with sell timestamps on or after June 1, 2024. These historical figures serve purely as quantitative research into algorithmic model design and do not represent guaranteed future results or live account profitability.
