English:
Welcome to Hengongbet Parlay Lab. This article aims to present a data-driven approach for building a profit model centered on football and Asian handicap markets, helping readers understand risk and reward within a rational, repeatable framework. Our emphasis is on long-term stability through historical data, statistical analysis, and bankroll management, rather than chasing short-term volatility. Please assess your own risk tolerance, comply with local laws, and practice responsible gaming before engaging in any betting activity.
一、背景与数据源 / Background and Data Sources
中文：
亚洲盘口提供了对手队伍实力差异的量化表达，常用于场地因素、伤病、战术变化等信息的折算。要构建盈利模型，关键在于获取高质量的盘口数据、赔率数据及比赛结果，同时关注盘口的历史走向与市场情绪。我们建议将数据分为三类：一是比赛基本面数据（球队状态、近期战绩、对阵历史等）；二是盘口与欧赔等市场数据（亚洲盘口、让球系数、胜负平赔率、赔率变化趋势）；三是结果与回测数据（最终结果、实际盈利、回撤等）。数据清洗、缺失值处理与时间对齐同样重要。
English:
Asian handicap markets provide a quantitative expression of team strength differences, incorporating factors such as home advantage, injuries, and tactical changes. To build a profitable model, the focus is on obtaining high-quality handicap data, odds data, and match results, while monitoring historical line movements and market sentiment. We categorize data into three groups: a) basic match data (team form, recent results, head-to-head history); b) market data (Asian handicap, spread coefficients, win/draw/lose odds, and movement trends); c) outcomes and backtesting data (actual results, realized profit, drawdown). Data cleaning, handling missing values, and proper time alignment are essential.
二、核心理论与概念 / Core Theory and Concepts
中文：
1) 价值投注与期望值：在单场或串关中，我们衡量每一条投注边缘的期望值（EV），以概率 p 与净赔率 b 的组合来表示。EV = p × b ? (1 ? p)。
2) 亚洲盘口的隐含概率：将盘口与公允概率对比，评估市场是否高估/低估某一方。通常需要将盘口转换为相应的隐含概率，再与球队实际概率进行对照。
3) 串关（Parlay/Accumulator）的边际与风险：多腿串关的潜在收益来自各腿赔率的乘积，但任一腿失利就全盘作废。理论上，若各腿独立且边际EV皆为正，整体EV需以组合概率和乘积赔率重新评估。
4) 凯利公式与资金管理：在确定单注金额时，利用凯利公式（或简化版本）来分配资金，以控制长期杠杆和回撤。
English:
1) Value betting and expected value (EV): For each bet or parlay, EV is assessed using probability p and net odds b. EV = p × b ? (1 ? p).
2) Implied probabilities in Asian handicap: Compare the handicap with fair probabilities to judge whether a side is over- or under-valued. Convert the handicap into an implied probability and compare it with the team’s actual probability.
3) Parlay risk and edge: The potential payoff comes from the product of leg odds, but any single losing leg cancels the entire bet. If each leg is independent and has positive EV, the overall EV should be reassessed taking into account the joint probability and compounded odds.
4) Kelly criterion and bankroll management: When sizing bets, apply (or adapt) the Kelly approach to allocate capital, aiming to control leverage and drawdown over time.
三、方法论：数据处理与建模 / Methodology: Data Processing and Modeling
中文：
- 数据准备：清洗赛事实时数据、盘口与赔率，统一时间戳，处理缺失值与异常点。
- 特征工程：从基本面（球队状态、主客场、伤病等）和市场面（盘口变化、赔率波动、流动性）提取特征，构建前向与后向检验窗口。
- 统计建模：可以采用逻辑回归、贝叶斯更新、以及简单的蒙特卡洛仿真来估算单腿胜率及串关胜率的区间。对多腿串关，需考虑相关性与独立性假设的敏感性。
- 回测框架：在历史数据上回测两类策略：A) 单腿正EV筛选+B) 串关组合的正EV评估。重点关注胜率、期望收益、夏普比率与最大回撤等指标。
- 风险与鲁棒性：对特征进行稳定性分析，评估市场波动对模型的影响，并设置阈值避免过度拟合。
English:
- Data preparation: Clean real-time match data, handicap and odds, unify timestamps, handle missing values and outliers.
- Feature engineering: Extract features from both fundamentals (team form, home/away, injuries) and market data (handicap movements, odds fluctuations, liquidity), and build forward and backward testing windows.
- Statistical modeling: Use logistic regression, Bayesian updating, and simple Monte Carlo simulations to estimate single-leg win probability and parlay win probability intervals. For multi-leg parlays, account for correlation and independence assumptions.
- Backtesting framework: Test two strategies on historical data: A) filter for positive EV on single legs; B) evaluate positive EV of parlay combinations. Focus on win rate, expected return, Sharpe ratio, and maximum drawdown.
- Risk and robustness: Perform stability analyses on features, assess the impact of market volatility, and set thresholds to avoid overfitting.
四、盈利模型设计 / Profit Model Design
中文：
- 单腿筛选：优先选择EV>0且样本规模稳健的单腿，作为可选的搭配基础。
- 串关构建原则：在多腿组合时，优先考虑相关性低、基本面与市场信号均支持的腿；对高相关性腿适度限额，降低整体波动。
- 投注策略：可采用分层投资（不同并列的 Parlay 版本），以控制总体暴露并实现渐进式增长。
- 概率与回报评估：对每个组合计算组合胜率、组合赔率与 EV，结合历史回测结果进行权衡。
- 示例：若两腿独立且各自 EV>0，且 p1、p2 分别为 0.55 与 0.60，d1 与 d2 分别为 2.0 与 1.8，则组合赔率 d1×d2=3.6，组合胜率 p1p2=0.33，EV 约为 0.33×(3.6?1)?(1?0.33)=0.33×2.6?0.67≈0.19，理论上呈现正向收益的潜力，但需警惕相关性与样本偏差。
English:
- Single-leg screening: Prioritize legs with positive EV and robust sample sizes as reliable building blocks.
- Parlay construction: When creating multi-leg combos, prefer legs with low correlation and signals supported by both fundamentals and markets; cap exposure to highly correlated legs to reduce volatility.
- Betting strategy: Use layered or staged parlay versions to control overall exposure and enable gradual growth.
- Probability and return assessment: Compute the combined win probability and payout for each portfolio, and weigh them against backtesting results to find a balanced approach.
- Example: If two legs are independent with EV>0, p1=0.55, p2=0.60, and odds d1=2.0, d2=1.8, then d1×d2=3.6, p1p2=0.33. EV ≈ 0.33×(3.6?1) ? (1?0.33) = 0.33×2.6 ? 0.67 ≈ 0.19. This suggests potential profitability, but correlation and sample bias must be carefully considered.
五、风险控制与资金管理 / Risk Control and Bankroll Management
中文：
- 风险限额：设定单日、单月与单次 Parlay 的最大亏损阈值，避免累积性回撤。
- 资金分配：采用分层或分段下注策略，结合凯利系数进行资金分配，但需在现实波动性下进行保守调整。
- 监控与调整：建立实时监控仪表盘，定期评估预测误差、回撤与模型漂移，必要时回退到简单基线策略。
- 合规与伦理：确保遵守当地法规，避免参与未成年人博彩、洗钱等违法行为。
English:
- Risk limits: Set maximum daily, monthly, and single-parlay loss thresholds to prevent cumulative drawdowns.
- Fund allocation: Use layered or segmented betting and apply a conservative adjustment to Kelly-based sizing in the face of real-world volatility.
- Monitoring and adjustment: Build real-time dashboards to evaluate forecast error, drawdown, and model drift; revert to simple baseline strategies if needed.
- Compliance and ethics: Ensure compliance with local regulations and avoid illegal activities such as underage gambling or money laundering.
六、实操路线图 / Practical Roadmap
中文：
- 阶段一：数据搭建与清洗，建立稳定的历史数据集与实时数据抓取管线。
- 阶段二：特征工程与单腿测试，锁定高信噪比的机会。
- 阶段三：串关策略初步设计，进行前瞻性回测与鲁棒性分析。
- 阶段四：小额风控实盘试水，逐步扩大规模并持续迭代模型。
- 阶段五：成果发布与持续优化，公开透明地记录边缘、回撤与实际收益。
English:
- Phase 1: Data construction and cleaning; establish a stable historical dataset and real-time data pipeline.
- Phase 2: Feature engineering and single-leg testing; identify high signal-to-noise opportunities.
- Phase 3: Initial parlay strategy design; conduct forward-testing and robustness analysis.
- Phase 4: Small-scale live testing with risk controls; gradually scale up while iterating the model.
- Phase 5: Publish results and pursue continuous optimization; transparently document edges, drawdown, and actual returns.
七、案例研究与实证要点 / Case Study and Empirical Highlights
中文：
- 假设情景：两腿独立、单腿 EV 均为正，示例参数如前所述；在历史窗口若干样本中检验，若背后的相关性较低且市场信号一致，组合的正向 EV 更有可能实现。
- 关键观察点：1) 相关性对结果的影响；2) 回测期内不同市场阶段的稳健性；3) 策略执行中的滑点与赔率波动。
- 实证要点总结：以稳健的单腿筛选为基础，辅以理性的串关配置和严格的风险控制，能提高长期的边际收益，但仍需警惕市场结构性变化与样本偏差。
English:
- Scenario: Two legs are independent with positive EV; using the parameter sets described earlier, testing across historical windows shows that lower leg correlation and aligned market signals increase the likelihood of positive EV for the parlay.
- Key observations: 1) The impact of leg correlation on results; 2) Robustness across different market regimes; 3) Slippage and odds volatility during execution.
- Empirical takeaway: A robust single-leg selection foundation, paired with disciplined parlay construction and strict risk controls, can improve long-term marginal gains, but market structural changes and sample bias must be watched.
